Fixed In Version: sssd-1.8.0-2.el6.beta2
Doc Type: Enhancement
Doc Text:
Cause: SSSD would maintain its connection to the LDAP server as long as possible, to avoid the overhead of reconnecting. Consequence: This could cause resource-limitation issues on the server, since SSSD clients would be tying up an available file descriptor. Change: SSSD now has a configurable idle timeout, after which it will disconnect from the LDAP server until the next request is received. Result: SSSD will be a less resource-intensive client for LDAP servers.

Description Ondrej Valousek 2011-10-07 12:59:27 UTC 
sssd should possibly not keep the connection to the LDAP server indefinitely as it could render the server to run out of resources.
Instead, we should close it after some (configurable) idle time.
