Yes and yes. The credentials and authentication process to the LDAP server
are working correctly as verified positively by the log files.

I am not aware of it or how it can help to solve this problem. Is there any
resource you can point to online that detail how to use this "rid"
backend
to do split authentication and authorization with an AD server and a
separate LDAP server? I will look into it myself, of course, but I have a
sad 16 hours sunk into trying to make this work with our CentOS 7 upgrade
and would appreciate any pointers.
