Steve - You're not the only person who has experienced a performance problem due to initgroups(); similar problems have been reported by people who authenticate via SQL.
There is currently no mechanism to disable the initgroups() call for the POP server only. As you've noted, it's very definitely necessary for the IMAP server. It shouldn't be too difficult to put in such a feature if it turns out that's the only feasible solution. However, IMHO disabling initgroups() for POP is just a band-aid for the real problem, which is the performance problem in initgroups() when used with NIS. This is something that should be taken up with your NIS vendor. The problem isn't going to go away and will get worse, even with the band-aid. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate.
