Description of problem:

sssd cache have invalid group, which already been deleted long time, but still in the cache, have the gid number: 1404.

and there is new group are using the gid again 1404. on the ldap side the gid number is uniqe, but in the sssd cache there are two entry with same gid, that cause id command can not get the group name.


id: cannot find name for group ID 1404

dump the cache:
# record 571
dn: name=xxxx1
createTimestamp: 1500531223
gidNumber: 1404
objectClass: group
isPosix: TRUE
...

# record 7521
dn: name=xxxx2
createTimestamp: 1495122412
gidNumber: 1404
objectClass: group
isPosix: TRUE

group name is different.xxxx2 is the old group, and after i try getent group xxxx2, then the old group is gone, i think the sssd found it's not exist in ldap, so remove it.

my quesiton, why this remove dose not happen when the ldap group remove in ldap server side.

sssd.conf:

reconnection_retries = 3
