Ticket was cloned from Red Hat Bugzilla (product Red Hat Enterprise Linux 6): Bug 953165
Please note that this Bug is private and may not be accessible as it contains confidential Red Hat customer information.
Steps to Reproduce:
1. Enable enumeration in sssd ldap domain with a significant amount of accounts
2. Fire off a `getent passwd` or something that hits nss and causes enumeration
2. Watch CPU spike to 100%
CPU spikes to 100%
CPU usage ~2%
Are we seeing some sort of regression? Looks like this amount of CPU usage is
excessive when compared to previous versions of sssd.
Lukas was triaging the bug and traced the regression down to commit e4fb78b

We'll need to release this fix in the maintenance branch, too. Moving to 1.9.6
milestone: SSSD 1.10 beta => SSSD 1.9.6
changelog: => Due to a logic bug in the LDAP provider, the SSSD was performing an unnecessary search when saving enumerated entries. This could have caused a CPU spike in large environments.
