Solved my issue!
The key wasn't from the messages running sssd using: /usr/sbin/sssd -D
-ddd and reading what was sent to screen.
Instead it was looking within the sssd_LDAP.log file itself:
(Wed Apr 29 11:42:58 2015) [sssd[be[LDAP]]] [sdap_access_filter_send]
(0x0400): No filter set.
(Wed Apr 29 11:42:58 2015) [sssd[be[LDAP]]] [sdap_access_done] (0x0400):
Access was denied.
The ldap_access_filter set to:
ldap_access_filter = ou=example,dc=ad,dc=example,dc=com
Appears this is not a filter.
To resolve, changed it to use:
ldap_access_filter =
memberof=cn=groupname,ou=groups,dc=ad,dc=example,dc=com
The documentation is a little vague for ldap_access_filter as to what
qualifies clearly as a filter.
malformed filter in the code didn't appear to get triggered?
Thanks again to Jakub and Sumit for taking the time to help!!!
