Re: editfiles methodology question

[Eli Stair]

I'm not the expert on this (as I haven't READ the relevant RFC's), but 
for instance when running Kerberos and Oracle (and probably other auth 
software as well) the best practice (and it's been stated RFC-compliant 
method) is to return FQDN for hostname lookups.

Not doing so will result in improper/non-functional Kerberos with 
tickets not applying to a host or service (been there).  Oracle can 
break all authenticated connectivity (been there too).  They even go so 
far as to recommend defining FQDN in /etc/hosts for all Oracle hosts to 
bypass any DNS/system-level problems with resolution.

Very over-simplified example, but a valid one I've had to deal with.
