Comment 5 for bug 591100

SRU team, as mentioned, this bug causes significant delays in automounting when your primary group is large (thousands of users). The bug has been addressed by increasing the group buffer size geometrically rather than linearly. If the primary group is small, there will be no change. The patch I originally provided still applies to the version in Lucid.

TEST CASE: Your primary group should have thousands of users, and you attempt access of something in an automount managed directory.
Expected result: It succeeds or fails quickly.
Prior to this fix it will take several seconds.

There are no expected regressions from this patch.
