You can have 'awk' count them for you. In the case of the 'root' group, I can issue the command "getent group root | awk -F, '{ print NF }'". See if the count is what you are expecting. If you are not getting the expected +2500 entries then you know it is not a PAM issue.

I can't test the getent command right now. we have a workaround in place that I'd have to disengage to test it out.
I'm at SP1. Pam version in SP1 is 0.99.6.3-28.8 and didn't change in sp2 – are there any specific packages you might recommend updating to sp2? It's not feasible for me to wholesale change the whole system to sp2, so targeting packages for experimentation would be easier.

Are you sure the issue is with pam_access? How many entries do you get when you run "getent group <grpname>" ?
Finally, what level SP are you at on your SLES10 machine? If you're not at SP2, you could try updating to that. I've found SP2 to have solved a lot of issues.

We have a site that uses pam to regulate user logins, and has a unix group in excess of 2500 user entries which is specified in the access.conf file.
They were running SLES9 (pam-0.77-221.4) and had no problems. However, updating to SLES10 (pam-0.99.6.3-28.8), they are now having problems with the group list truncating at about 1100 user entries.
Was some default limit changed? I checked the archives, but didn't see anything blatent announcing this. I checked the ChangeLog in the source code and found an entry that is suspicious (2005-12-21 Tomas Mraz simplifying evaluate_ingroup), but again, nothing blatent.
What is the limit? How can I change it (preferably without recompiling)? Is this at all possible?
Thanks,
Wendy
