Fixed In Version:	sssd-1.9.2-115.el6	Doc Type:	Known Issue
Doc Text:	It is possible to specify the enumerate=true value in the sssd.conf file to access all users in the system. However, using enumerate=true is not recommended in large environments as this can lead to high CPU consumption. As a result, operations like login or logout can be slowed down.	Story Points:	---

Description Dmitri Pal 2013-01-03 14:26:03 UTC

This is the release note bug.

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1732

Many users set enumerate=true in their configuration for convenience of being able to access all the users. We should explain that enumeration might not be a great idea in big environments due to bugs like #1729.
