Ditto here. getent group large group now works for various groups 1000 and does not crash winbind with the samba version from poposed. getent group Domain Users now only returns #getent group Domain Users domain users:x:5000513: But this does not crash winbind, which is the main thing. wbinfo -u still crashes winbind, but I see that as a separate issue, and it does not hinder normal operations.

[Bug 970679] Re: [SRU] winbind coredumps when encountering a group with over 1000 members
** Description changed: Impact: winbind coredumps when encountering a group with more that 1000 members - this renders winbind unusable in deployments with 1000 users in a single group. Development Fix: Cherry picked patch from upstream VCS - this fix should be included in 3.6.6. + Fix ensures that hunks of 1000 entries processed in winbind line up with talloc memory handling preventing the crash. Stable Fix: + Cherry picked patch from upstream VCS - see comments in Development fix. Test Case: + NOTE - hard to reproduce as requires deployment with large number of users/groups. Configure winbind to communicate with a Domain Controller with more that 1000 users getent group groupWithLessThan1000Members - OK getent group groupWithMoreThan1000Members - HANGS (coredumps recorded in syslog).
