Title: SSSD support for automount map caching
In Red Hat Enterprise Linux 6.3, SSSD includes a new Technology Preview feature: support for caching automount maps. This feature provides several advantages to environments that operate with autofs:
Cached automount maps make it easy for a client machine to perform mount operations even when the LDAP server is unreachable, but the NFS server remains reachable.
When the autofs daemon is configured to look up automount maps via SSSD, only a single file has to be configured: /etc/sssd.conf. Previously, the /etc/sysconfig/autofs file had to be configured to fetch autofs data.
Caching the automount maps results in faster performance on the client and lower traffic on the LDAP server.
