Currently our enumeration logic makes two passes: In the first pass, it creates all of the users in the cache. In the second pass, it creates all of the groups. We need to split the second pass into a second and third pass, so that we have: Pass 1: Create users Pass 2: Create empty groups Pass 3: Populate group members The reason some nested groups were not unrolled is that the order of their creation would matter. If they weren't already in the sysdb when another group wanted to add them as a member, they would be overlooked. Tracking this issue upstream at https://fedorahosted.org/sssd/ticket/779 DS setup: 1. Server setup: (make sure all users have primary group defined) SimpleGroup1 => simpleUserA simpleUserB simpleGroup3 SimpleGroup2 => simpleUserC simpleUserD SimpleGroup3 => simpleUserE On Client: # getent passwd simpleuserE simpleuserE:*:8005:8005:simpleuserE:/home/simpleuserE:/bin/bash # id -G -n simpleuserE simplegroupE simplegroup3 simplegroup1 # ssh -l simpleuserE localhost simpleuserE@localhost's password: Creating directory '/home/simpleuserE'.

Created attachment 474249 [details] Complete sssd_LDAP.log Description of problem: Nested groups are not unrolled during the first enumeration causing authentication of the users in nested group to fail, however authentication succeeds after the second enumeration. Version-Release number of selected component (if applicable): sssd-1.5.0-2.el6.x86_64 How reproducible: Always Steps to Reproduce: DS setup: 1. Server setup: (make sure all users have primary group defined) SimpleGroup1 => simpleUserA simpleUserB simpleGroup3 SimpleGroup2 => simpleUserC simpleUserD SimpleGroup3 => simpleUserE 2. Configure SSSD with "enumerate = true". See additional info for relevant configuration. 3. restart sssd clearing cache. 4. Try authenticating with simpleuserE (which is a memberOf simplegroup3 which is a memberOf simplegroup1) Actual results: Authentication fails initially and succeeds after the second enumeration. Expected results: Authentication should succeed after the first enumeration. Additional info: 1. Relevant sssd configuration: [domain/LDAP] id_provider = ldap auth_provider = ldap ldap_uri = ldaps://rhdsserver.redhat.com:636 ldap_search_base = dc=example,dc=com ldap_tls_reqcert = demand ldap_tls_cacertdir = /etc/openldap/cacerts ldap_tls_cacert = /etc/openldap/cacerts/cacert.asc ldap_schema = rfc2307bis cache_credentials = true enumerate = true debug_level = 9 access_provider = simple simple_allow_groups = simplegroup1
