Description Jakub Hrozek 2014-09-03 20:23:08 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2102

If periodical refresh of expired netgroups is enabled, we should disable async midpoint refresh (only for netgroups), since it is not useful anymore - all netgroups are kept up to date.

Tests showed that having midpoint refresh enabled may actually slow down netgroup request occasionally.

Comment 3 Kaushik Banerjee 2014-12-30 10:14:43 UTC

There is a minor typo in the logging. "then" should be "than".

[sssd[be[LDAP]]] [confdb_get_domain_internal] (0x0100): refresh_expired_interval (20000) cannot be greater then entry_cache_timeout (5400)
