SSSD does not enumerate all groups with id command, if user is a member of large number of nested groups.

Solution Verified - Updated -

Issue

  • SSSD does not enumerate all groups with id command, if user is a member of large number of nested groups.

    # id testuser | grep -i --color group1



# getent group group1
group1:*:[ SNIP ],group2



# id testuser | grep -i --color group1
[ SNIP ] ,15673(group1) context=user_u:system_r:unconfined_t

  • Since users are not in the previleged group, they are not able to login due to the above issue.

Environment

  • Red Hat Enterprise Linux 5, 6
  • SSSD
