Description of problem: sssd crashes during initgroups against a user belonging to nested rfc2307bis group. Version-Release number of selected component (if applicable): sssd-1.8.0-2.el6.beta2.x86_64 How reproducible: Always Steps to Reproduce: 1. Configure sssd as follows: [domain/openldap] debug_level = 9 id_provider = ldap ldap_uri = ldap://ldapserver.example.com ldap_search_base = dc=example,dc=com cache_credentials = true ldap_tls_cacert = /etc/openldap/cacerts/server.pem ldap_schema = rfc2307bis ldap_group_object_class = groupOfNames 2. Add a user using the following ldif: dn: uid=mof_user2,dc=example,dc=com objectClass: account objectClass: posixAccount cn: memberof_user2 uidNumber: 22222 gidNumber: 22222 homeDirectory: /home/mof_user2 loginShell: /bin/bash gecos: MEMBEROF USER2 userPassword: Secret123 dn: cn=mof_user2_grp1,dc=example,dc=com gidNumber: 22222 objectClass: extensibleObject objectClass: groupOfNames member: uid=mof_user2,dc=example,dc=com dn: cn=mof_user2_grp2,dc=example,dc=com gidNumber: 22223 objectClass: extensibleObject objectClass: groupOfNames member: cn=mof_user2_grp1,dc=example,dc=com dn: cn=mof_user2_grp3,dc=example,dc=com gidNumber: 22224 objectClass: extensibleObject objectClass: groupOfNames member: cn=mof_user2_grp2,dc=example,dc=com dn: cn=mof_user2_grp4,dc=example,dc=com gidNumber: 22225 objectClass: extensibleObject objectClass: groupOfNames member: cn=mof_user2_grp3,dc=example,dc=com 3. Perform initgroups operation on the user: # id mof_user2 Actual results: Running "id mof_user2" hangs. And sssd_be crashes. Expected results: initgroups operation succeeds. Additional info: 1.
