From f643fadbd072a9d3725f5f750340d5b13628ce6a Mon Sep 17 00:00:00 2001 From: Sumit Bose Date: Tue, 28 Apr 2015 17:20:05 +0200 Subject: [PATCH 78/99] IPA: update initgr expire timestamp conditionally Newer versions of the extdom plugin return the full list of group-memberships during user lookups. As a result the lifetime of the group-membership data is updates in those cases. But if the user is not looked up directly but is resolved as a group member during a group lookup SSSD does not resolve all group-membership of the user to avoid deep recursion and eventually a complete enumeration of the user and group base. In this case the lifetime of the group-memberships should not be updated because it might be incomplete.
