Doc Text:	Cause: Even if a user entry was cached by the SSSD, it had to be read from the cache file on disk Consequence: The cache reads might have been slow in some performance-critical environments. Change: A new layer of cache, stored in memory was introduced. Result: The performance of returning cached entries was improved by an order of magnitude	Story Points:	---

Description Dmitri Pal 2012-02-10 22:47:24 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/357

SSSD is currently in conflict with the NSCD. It is recommended not to use NSCD with the maps SSSD provides. But performance of the SSSD is not sufficient to address all the exiting requirements. SSSD should be enhanced to provide an NSCD type in memory cache solution that would meet these requirements.
