#1713 [RFE] Add a task to the SSSD to periodically refresh cached entries
Closed: Fixed None Opened 6 years ago by jhrozek.

This RFE came up during a discussion between Chris Hudson, Simo and me. Some deployments suffer from latency when refreshing a big number of expired entries, for instance during logins that involve refreshing netgroups.

The latency might be mitigated by introducing a new background task that would walk the database periodically and fire a refresh in the background for any entry that is past a threshold


What is the criteria regarding which entries to update? Is it any entry that is old enough or there is also a filter, i.e refresh only: users, groups, services, netgroups, sudo rules, automount maps, SSH data, HBAC, or SELinux mappings?
