Hi,
I wrote the following patches while testig the ipa_server_mode. While
the first three are needed fixes the fourth patch is an improvement
which might help to avoid an additional request to the LDAP server.
bye,
Sumit

Subject: [PATCH 4/4] sysdb_add_incomplete_group: store SID string is
available
During initgroups request we read the SID of a group from the server but
do not save it to the cache. This patch fixes this and might help to
avoid an additional lookup of the SID later.
