Thanks to a subsequent fix, i.e. a couple files to drop into the glibc
source, we now have a glibc/nscd-2.2.4 that handles large groups with
aplomb. This was really important for us since it lets us use
pam_listfile to restrict logins by group membership in LDAP. Having to
generate lists of users allowed to login would have been very annoying.
Many thanks for the quick help, Ulrich.
I take it this was indeed a glibc bug, and not anything specific to
RedHat? Just curious.
Cheers,
