[Help-gnu-radius] Openser + Freeradius + Active Directory


From: Artur Hayne
Subject: [Help-gnu-radius] Openser + Freeradius + Active Directory
Date: Thu, 17 Aug 2006 09:25:29 -0300 (ART)

 Hi,
 
 I have a openser that use the freeradius to authenticate in Active Directory  
(ldap server for windows), but its dont word.
 
 This is the debug of FreeRadius:
 
  radius_xlat:  'ou=2396,dc=intranet,dc=ufba,dc=br'
  rlm_ldap: ldap_get_conn: Checking Id: 0
  rlm_ldap: ldap_get_conn: Got Id: 0
  rlm_ldap: performing search in ou=2396,dc=intranet,dc=ufba,dc=br, with filter 
(uid=jab)
  rlm_ldap: object not found or got ambiguous search result
  rlm_ldap: search failed
  rlm_ldap: ldap_release_conn: Release Id: 0
    modcall[authorize]: module "ldap" returns notfound for request 47
  modcall: leaving group authorize (returns ok) for request 47
    rad_check_password:  Found Auth-Type DIGEST
  auth: type "digest"
    Processing the authenticate section of radiusd.conf
  modcall: entering group authenticate for request 47
  rlm_digest: Configuration item "User-Password" or MD5-Password is required 
for authentication.
    modcall[authenticate]: module "digest" returns invalid for request 47
  modcall: leaving group authenticate (returns invalid) for request 47
   auth: Failed to validate the user.
 
 my radiusd.conf:
 
 
refix = /usr/local
exec_prefix = ${prefix}
sysconfdir = /usr/local/etc/
localstatedir = ${prefix}/var
sbindir = ${exec_prefix}/sbin
logdir = ${localstatedir}/log/radius
raddbdir = ${sysconfdir}/raddb
radacctdir = ${logdir}/radacct

#  Location of config and logfiles.
confdir = ${raddbdir}
run_dir = ${localstatedir}/run/radiusd

#
#  The logging messages for the server are appended to the
#  tail of this file.
#
log_file = ${logdir}/radius.log

#
# libdir: Where to find the rlm_* modules.
#
#   This should be automatically set at configuration time.
#
#   If the server builds and installs, but fails at execution time
#   with an 'undefined symbol' error, then you can use the libdir
#   directive to work around the problem.
#
#   The cause is usually that a library has been installed on your
#   system in a place where the dynamic linker CANNOT find it.  When
#   executing as root (or another user), your personal environment MAY
#   be set up to allow the dynamic linker to find the library.  When
#   executing as a daemon, FreeRADIUS MAY NOT have the same
#   personalized configuration.
#
#   To work around the problem, find out which library contains that 
symbol,
#   and add the directory containing that library to the end of 
'libdir',
#   with a colon separating the directory names.  NO spaces are 
allowed.
#
#   e.g. libdir = /usr/local/lib:/opt/package/lib
#
#   You can also try setting the LD_LIBRARY_PATH environment variable
#   in a script which starts the server.
#
#   If that does not work, then you can re-configure and re-build the
#   server to NOT use shared libraries, via:
#
# ./configure --disable-shared
# make
# make install
#
libdir = ${exec_prefix}/lib

#  pidfile: Where to place the PID of the RADIUS server.
#
#  The server may be signalled while it's running by using this
#  file.
#
#  This file is written when ONLY running in daemon mode.
#
#  e.g.:  kill -HUP `cat /var/run/radiusd/radiusd.pid`
#
pidfile = ${run_dir}/radiusd.pid


# user/group: The name (or #number) of the user/group to run radiusd 
as.
#
#   If these are commented out, the server will run as the user/group
#   that started it.  In order to change to a different user/group, you
#   MUST be root ( or have root privleges ) to start the server.
#
#   We STRONGLY recommend that you run the server with as few 
permissions
#   as possible.  That is, if you're not using shadow passwords, the
#   user and group items below should be set to 'nobody'.
#
#    On SCO (ODT 3) use "user = nouser" and "group = nogroup".
#
#  NOTE that some kernels refuse to setgid(group) when the value of
#  (unsigned)group is above 60000; don't use group nobody on these 
systems!
#
#  On systems with shadow passwords, you might have to set 'group = 
shadow'
#  for the server to be able to read the shadow password file.  If you 
can
#  authenticate users while in debug mode, but not in daemon mode, it 
may be
#  that the debugging mode server is running as a user that can read 
the
#  shadow info, and the user listed below can not.
#
#user = nobody
#group = nobody

#  max_request_time: The maximum time (in seconds) to handle a request.
#
#  Requests which take more time than this to process may be killed, 
and
#  a REJECT message is returned.
#
#  WARNING: If you notice that requests take a long time to be handled,
#  then this MAY INDICATE a bug in the server, in one of the modules
#  used to handle a request, OR in your local configuration.
#
#  This problem is most often seen when using an SQL database.  If it 
takes
#  more than a second or two to receive an answer from the SQL 
database,
#  then it probably means that you haven't indexed the database.  See 
your
#  SQL server documentation for more information.
#
#  Useful range of values: 5 to 120
#
max_request_time = 30

#  delete_blocked_requests: If the request takes MORE THAN 
'max_request_time'
#  to be handled, then maybe the server should delete it.
#
#  If you're running in threaded, or thread pool mode, this setting
#  should probably be 'no'.  Setting it to 'yes' when using a threaded
#  server MAY cause the server to crash!
#
delete_blocked_requests = no

#  cleanup_delay: The time to wait (in seconds) before cleaning up
#  a reply which was sent to the NAS.
#
#  The RADIUS request is normally cached internally for a short period
#  of time, after the reply is sent to the NAS.  The reply packet may 
be
#  lost in the network, and the NAS will not see it.  The NAS will then
#  re-send the request, and the server will respond quickly with the
#  cached reply.
#
#  If this value is set too low, then duplicate requests from the NAS
#  MAY NOT be detected, and will instead be handled as seperate 
requests.
#
#  If this value is set too high, then the server will cache too many
#  requests, and some new requests may get blocked.  (See 
'max_requests'.)
#
#  Useful range of values: 2 to 10
#
cleanup_delay = 5

#  max_requests: The maximum number of requests which the server keeps
#  track of.  This should be 256 multiplied by the number of clients.
#  e.g. With 4 clients, this number should be 1024.
#
#  If this number is too low, then when the server becomes busy,
#  it will not respond to any new requests, until the 'cleanup_delay'
#  time has passed, and it has removed the old requests.
#
#  If this number is set too high, then the server will use a bit more
#  memory for no real benefit.
#
#  If you aren't sure what it should be set to, it's better to set it
#  too high than too low.  Setting it to 1000 per client is probably
#  the highest it should be.
#
#  Useful range of values: 256 to infinity
#
max_requests = 1024

#  bind_address:  Make the server listen on a particular IP address, 
and
#  send replies out from that address.  This directive is most useful
#  for machines with multiple IP addresses on one interface.
#
#  It can either contain "*", or an IP address, or a fully qualified
#  Internet domain name.  The default is "*"
#
#  As of 1.0, you can also use the "listen" directive.  See below for
#  more information.
#
bind_address = *

#  port: Allows you to bind FreeRADIUS to a specific port.
#
#  The default port that most NAS boxes use is 1645, which is 
historical.
#  RFC 2138 defines 1812 to be the new port.  Many new servers and
#  NAS boxes use 1812, which can create interoperability problems.
#
#  The port is defined here to be 0 so that the server will pick up
#  the machine's local configuration for the radius port, as defined
#  in /etc/services.
#
#  If you want to use the default RADIUS port as defined on your 
server,
#  (usually through 'grep radius /etc/services') set this to 0 (zero).
#
#  A port given on the command-line via '-p' over-rides this one.
#
#  As of 1.0, you can also use the "listen" directive.  See below for
#  more information.
#
port = 0

#
#  By default, the server uses "bind_address" to listen to all IP's
#  on a machine, or just one IP.  The "port" configuration is used
#  to select the authentication port used when listening on those
#  addresses.
#
#  If you want the server to listen on additional addresses, you can
#  use the "listen" section.  A sample section (commented out) is 
included
#  below.  This "listen" section duplicates the functionality of the
#  "bind_address" and "port" configuration entries, but it only listens
#  for authentication packets.
#
#  If you comment out the "bind_address" and "port" configuration 
entries,
#  then it becomes possible to make the server accept only accounting,
#  or authentication packets.  Previously, it always listened for both
#  types of packets, and it was impossible to make it listen for only
#  one type of packet.
#
#listen {
 #  IP address on which to listen.
 #  Allowed values are:
 # dotted quad (1.2.3.4)
 #       hostname    (radius.example.com)
 #       wildcard    (*)
# ipaddr = *

 #  Port on which to listen.
 #  Allowed values are:
 # integer port number (1812)
 # 0 means "use /etc/services for the proper port"
# port = 0

 #  Type of packets to listen for.
 #  Allowed values are:
 # auth listen for authentication packets
 # acct listen for accounting packets
 #
# type = auth
#}


#  hostname_lookups: Log the names of clients or just their IP 
addresses
#  e.g., www.freeradius.org (on) or 206.47.27.232 (off).
#
#  The default is 'off' because it would be overall better for the net
#  if people had to knowingly turn this feature on, since enabling it
#  means that each client request will result in AT LEAST one lookup
#  request to the nameserver.   Enabling hostname_lookups will also
#  mean that your server may stop randomly for 30 seconds from time
#  to time, if the DNS requests take too long.
#
#  Turning hostname lookups off also means that the server won't block
#  for 30 seconds, if it sees an IP address which has no name 
associated
#  with it.
#
#  allowed values: {no, yes}
#
hostname_lookups = no

#  Core dumps are a bad thing.  This should only be set to 'yes'
#  if you're debugging a problem with the server.
#
#  allowed values: {no, yes}
#
allow_core_dumps = no

#  Regular expressions
#
#  These items are set at configure time.  If they're set to "yes",
#  then setting them to "no" turns off regular expression support.
#
#  If they're set to "no" at configure time, then setting them to "yes"
#  WILL NOT WORK.  It will give you an error.
#
regular_expressions = yes
extended_expressions = yes

#  Log the full User-Name attribute, as it was found in the request.
#
# allowed values: {no, yes}
#
log_stripped_names = no

#  Log authentication requests to the log file.
#
#  allowed values: {no, yes}
#
log_auth = no

#  Log passwords with the authentication requests.
#  log_auth_badpass  - logs password if it's rejected
#  log_auth_goodpass - logs password if it's correct
#
#  allowed values: {no, yes}
#
log_auth_badpass = no
log_auth_goodpass = no

# usercollide:  Turn "username collision" code on and off.  See the
# "doc/duplicate-users" file
#
#  WARNING
#  !!!!!!!  Setting this to "yes" may result in the server behaving
#  !!!!!!!  strangely.  The "username collision" code will ONLY work
#  !!!!!!!  with clear-text passwords.  Even then, it may not do what
#  !!!!!!!  you want, or what you expect.
#  !!!!!!!
#  !!!!!!!  We STRONGLY RECOMMEND that you do not use this feature,
#  !!!!!!!  and that you find another way of acheiving the same goal.
#  !!!!!!!
#  !!!!!!!  e,g. module fail-over.  See 'doc/configurable_failover'
#  WARNING
#
usercollide = no

# lower_user / lower_pass:  
# Lower case the username/password "before" or "after"
# attempting to authenticate.  
#
#  If "before", the server will first modify the request and then try
#  to auth the user.  If "after", the server will first auth using the
#  values provided by the user.  If that fails it will reprocess the
#  request after modifying it as you specify below.
#
#  This is as close as we can get to case insensitivity.  It is the
#  admin's job to ensure that the username on the auth db side is
#  *also* lowercase to make this work
#
# Default is 'no' (don't lowercase values)
# Valid values = "before" / "after" / "no"
#
lower_user = no
lower_pass = no

# nospace_user / nospace_pass:
#
#  Some users like to enter spaces in their username or password
#  incorrectly.  To save yourself the tech support call, you can
#  eliminate those spaces here:
#
# Default is 'no' (don't remove spaces)
# Valid values = "before" / "after" / "no" (explanation above)
#
nospace_user = no
nospace_pass = no

checkrad = ${sbindir}/checkrad

# SECURITY CONFIGURATION
#
#  There may be multiple methods of attacking on the server.  This
#  section holds the configuration items which minimize the impact
#  of those attacks
#
security {
 #
 #  max_attributes: The maximum number of attributes
 #  permitted in a RADIUS packet.  Packets which have MORE
 #  than this number of attributes in them will be dropped.
 #
 #  If this number is set too low, then no RADIUS packets
 #  will be accepted.
 #
 #  If this number is set too high, then an attacker may be
 #  able to send a small number of packets which will cause
 #  the server to use all available memory on the machine.
 #
 #  Setting this number to 0 means "allow any number of attributes"
 max_attributes = 200

 #
 #  delayed_reject: When sending an Access-Reject, it can be
 #  delayed for a few seconds.  This may help slow down a DoS
 #  attack.  It also helps to slow down people trying to brute-force
 #  crack a users password.
 #
 #  Setting this number to 0 means "send rejects immediately"
 #
 #  If this number is set higher than 'cleanup_delay', then the
 #  rejects will be sent at 'cleanup_delay' time, when the request
 #  is deleted from the internal cache of requests.
 #
 #  Useful ranges: 1 to 5
 reject_delay = 1

 #
 #  status_server: Whether or not the server will respond
 #  to Status-Server requests.
 #
 #  Normally this should be set to "no", because they're useless.
 #  See: http://www.freeradius.org/rfc/rfc2865.html#Keep-Alives
 #
 #  However, certain NAS boxes may require them. 
 #
 #  When sent a Status-Server message, the server responds with
 #  an Access-Accept packet, containing a Reply-Message attribute,
 #  which is a string describing how long the server has been
 #  running.
 #
 status_server = no
}

# PROXY CONFIGURATION
#
#  proxy_requests: Turns proxying of RADIUS requests on or off.
#
#  The server has proxying turned on by default.  If your system is NOT
#  set up to proxy requests to another server, then you can turn 
proxying
#  off here.  This will save a small amount of resources on the server.
#
#  If you have proxying turned off, and your configuration files say
#  to proxy a request, then an error message will be logged.
#
#  To disable proxying, change the "yes" to "no", and comment the
#  $INCLUDE line.
#
#  allowed values: {no, yes}
#
proxy_requests  = yes
$INCLUDE  ${confdir}/proxy.conf


# CLIENTS CONFIGURATION
#
#  Client configuration is defined in "clients.conf".  
#

#  The 'clients.conf' file contains all of the information from the old
#  'clients' and 'naslist' configuration files.  We recommend that you
#  do NOT use 'client's or 'naslist', although they are still
#  supported.
#
#  Anything listed in 'clients.conf' will take precedence over the
#  information from the old-style configuration files.
#
$INCLUDE  ${confdir}/clients.conf


# SNMP CONFIGURATION
#
#  Snmp configuration is only valid if SNMP support was enabled
#  at compile time.
#
#  To enable SNMP querying of the server, set the value of the
#  'snmp' attribute to 'yes'
#
snmp = no
$INCLUDE  ${confdir}/snmp.conf


# THREAD POOL CONFIGURATION
#
#  The thread pool is a long-lived group of threads which
#  take turns (round-robin) handling any incoming requests.
#
#  You probably want to have a few spare threads around,
#  so that high-load situations can be handled immediately.  If you
#  don't have any spare threads, then the request handling will
#  be delayed while a new thread is created, and added to the pool.
#
#  You probably don't want too many spare threads around,
#  otherwise they'll be sitting there taking up resources, and
#  not doing anything productive.
#
#  The numbers given below should be adequate for most situations.
#
thread pool {
 #  Number of servers to start initially --- should be a reasonable
 #  ballpark figure.
 start_servers = 5

 #  Limit on the total number of servers running.
 #
 #  If this limit is ever reached, clients will be LOCKED OUT, so it
 #  should NOT BE SET TOO LOW.  It is intended mainly as a brake to
 #  keep a runaway server from taking the system with it as it spirals
 #  down...
 #
 #  You may find that the server is regularly reaching the
 #  'max_servers' number of threads, and that increasing
 #  'max_servers' doesn't seem to make much difference.
 #
 #  If this is the case, then the problem is MOST LIKELY that
 #  your back-end databases are taking too long to respond, and
 #  are preventing the server from responding in a timely manner.
 #
 #  The solution is NOT do keep increasing the 'max_servers'
 #  value, but instead to fix the underlying cause of the
 #  problem: slow database, or 'hostname_lookups=yes'.
 #
 #  For more information, see 'max_request_time', above.
 #
 max_servers = 32

 #  Server-pool size regulation.  Rather than making you guess
 #  how many servers you need, FreeRADIUS dynamically adapts to
 #  the load it sees, that is, it tries to maintain enough
 #  servers to handle the current load, plus a few spare
 #  servers to handle transient load spikes.
 #
 #  It does this by periodically checking how many servers are
 #  waiting for a request.  If there are fewer than
 #  min_spare_servers, it creates a new spare.  If there are
 #  more than max_spare_servers, some of the spares die off.
 #  The default values are probably OK for most sites.
 #
 min_spare_servers = 3
 max_spare_servers = 10

 #  There may be memory leaks or resource allocation problems with
 #  the server.  If so, set this value to 300 or so, so that the
 #  resources will be cleaned up periodically.
 #
 #  This should only be necessary if there are serious bugs in the
 #  server which have not yet been fixed.
 #
 #  '0' is a special value meaning 'infinity', or 'the servers never
 #  exit'

# MODULE CONFIGURATION
#
#  The names and configuration of each module is located in this 
section.
#
#  After the modules are defined here, they may be referred to by name,
#  in other sections of this configuration file.
#
modules {
 #
 #  Each module has a configuration as follows:
 #
 # name [ instance ] {
 #  config_item = value
 #  ...
 # }
 #
 #  The 'name' is used to load the 'rlm_name' library
 #  which implements the functionality of the module.
 #
 #  The 'instance' is optional.  To have two different instances
 #  of a module, it first must be referred to by 'name'.
 #  The different copies of the module are then created by
 #  inventing two 'instance' names, e.g. 'instance1' and 'instance2'
 #
 #  The instance names can then be used in later configuration
 #  INSTEAD of the original 'name'.  See the 'radutmp' configuration
 #  below for an example.

 # delimiter      -  must be a single character
 # ignore_default -  set to 'yes' or 'no'
 #       ignore_null    -  set to 'yes' or 'no'
 #
 #  ignore_default and ignore_null can be set to 'yes' to prevent

 #  A simple value checking module
 #
 #  It can be used to check if an attribute value in the request
 #  matches a (possibly multi valued) attribute in the check
 #  items This can be used for example for caller-id
 #  authentication.  For the module to run, both the request
 #  attribute and the check items attribute must exist
 #
 #  i.e.
 #  A user has an ldap entry with 2 radiusCallingStationId
 #  attributes with values "12345678" and "12345679".  If we
 #  enable rlm_checkval, then any request which contains a
 #  Calling-Station-Id with one of those two values will be
 #  accepted.  Requests with other values for
 #  Calling-Station-Id will be rejected.
 #
 #  Regular expressions in the check attribute value are allowed
 #  as long as the operator is '=~'
 #
 #checkval {
  # The attribute to look for in the request
 # item-name = Calling-Station-Id

  # The attribute to look for in check items. Can be multi valued
 # check-name = Calling-Station-Id

  # The data type. Can be
  # string,integer,ipaddr,date,abinary,octets
 # data-type = string

  # If set to yes and we dont find the item-name attribute in the
  # request then we send back a reject
  # DEFAULT is no
  #notfound-reject = no
 #}
 
 #  rewrite arbitrary packets.  Useful in accounting and authorization.
 #
 #
 #  The module can also use the Rewrite-Rule attribute. If it
 #  is set and matches the name of the module instance, then
 #  that module instance will be the only one which runs.
 #
 #  Also if new_attribute is set to yes then a new attribute
 #  will be created containing the value replacewith and it
 #  will be added to searchin (packet, reply, proxy, proxy_reply or 
config).
 # searchfor,ignore_case and max_matches will be ignored in that case.
 #
 # Backreferences are supported: %{0} will contain the string the whole 
match
 # and %{1} to %{8} will contain the contents of the 1st to the 8th 
parentheses
 #
 # If max_matches is greater than one the backreferences will 
correspond to the

 #  counter module:
 #  This module takes an attribute (count-attribute).
 #  It also takes a key, and creates a counter for each unique
 #  key.  The count is incremented when accounting packets are
 #  received by the server.  The value of the increment depends
 #  on the attribute type.
 #  If the attribute is Acct-Session-Time or of an integer type we add 
the
 #  value of the attribute. If it is anything else we increase the
 #  counter by one.
 #
 #  The 'reset' parameter defines when the counters are all reset to
 #  zero.  It can be hourly, daily, weekly, monthly or never.
 #
 #  hourly: Reset on 00:00 of every hour
 #  daily: Reset on 00:00:00 every day
 #  weekly: Reset on 00:00:00 on sunday
 #  monthly: Reset on 00:00:00 of the first day of each month
 #
 #  It can also be user defined. It should be of the form:
 #  num[hdwm] where:
 #  h: hours, d: days, w: weeks, m: months
 #  If the letter is ommited days will be assumed. In example:
 #  reset = 10h (reset every 10 hours)
 #  reset = 12  (reset every 12 days)
 #
 #
 #  The check-name attribute defines an attribute which will be
 #  registered by the counter module and can be used to set the
 #  maximum allowed value for the counter after which the user
 #  is rejected.
 #  Something like:
 #
 #  DEFAULT Max-Daily-Session := 36000
 #          Fall-Through = 1
 #
 #  You should add the counter module in the instantiate
 #  section so that it registers check-name before the files
 #  module reads the users file.
 #
 #  If check-name is set and the user is to be rejected then we
 #  send back a Reply-Message and we log a Failure-Message in
 #  the radius.log
 #  If the count attribute is Acct-Session-Time then on each login
 #  we send back the remaining online time as a Session-Timeout 
attribute
 #
 #  The counter-name can also be used instead of using the check-name
 #  like below:
 #
 #  DEFAULT  Daily-Session-Time > 3600, Auth-Type = Reject
 #      Reply-Message = "You've used up more than one hour today"
 #
 #  The allowed-servicetype attribute can be used to only take
 #  into account specific sessions. For example if a user first
 #  logs in through a login menu and then selects ppp there will
 #  be two sessions. One for Login-User and one for Framed-User
 #  service type. We only need to take into account the second one.
 #
 #  The module should be added in the instantiate, authorize and
 #  accounting sections.  Make sure that in the authorize
 #  section it comes after any module which sets the
 #  'check-name' attribute.

# Instantiation
#
#  This section orders the loading of the modules.  Modules
#  listed here will get loaded BEFORE the later sections like
#  authorize, authenticate, etc. get examined.
#
#  This section is not strictly needed.  When a section like
#  authorize refers to a module, it's automatically loaded and
#  initialized.  However, some modules may not be listed in any
#  of the following sections, so they can be listed here.
#
#  Also, listing modules here ensures that you have control over
#  the order in which they are initalized.  If one module needs
#  something defined by another module, you can list them in order
#  here, and ensure that the configuration will be OK.

 #  The expression module doesn't do authorization,

 #  listed in any other section.  See 'doc/rlm_expr' for

#  Authentication.
#
#
#  This section lists which modules are available for authentication.
#  Note that it does NOT mean 'try each module in order'.  It means
#  that a module from the 'authorize' section adds a configuration
#  attribute 'Auth-Type := FOO'.  That authentication type is then
#  used to pick the apropriate module from the list below.
#

#  In general, you SHOULD NOT set the Auth-Type attribute.  The server
#  will figure it out on its own, and will do the right thing.  The
#  most common side effect of erroneously setting the Auth-Type
#  attribute is that one authentication method will work, but the
#  others will not.
#
#  The common reasons to set the Auth-Type attribute by hand
#  is to either forcibly reject the user, or forcibly accept him.

 what happend?
 Its necessarily confgiured the users file or eap.conf? What kind of line I put

 Thankss...
