Getent group <group> returns incomplete member list after enumeration switched off in sssd

Solution Unverified - Updated -

Issue

  • When a user is removed from the cache after the normal time out, the groups he is a member of do not longer list the user when doing a "getent group".
  • The situation lasts until the group is updated (typical 45 minutes).
  • What I see is that the sssd_cache does not have the user restored as a "ghost", so when the user expires and is removed as a group member but is not restored as a "ghost" member.
  • This only happens after the group expires. This means for about 45 minutes a "getent group " does not show the user as a member.

Environment

  • Red Hat Enterprise Linux (RHEL) 6.6
  • System Security Services Daemon (SSSD) 1.11.6-30.el6
  • Enumeration turned off
