ERROR: value does not conform to assertion syntax

[Sudhakar <sudhakar@co.brazos.tx.us>]

When trying to enforce role based authentication using apache's auth_ldap module I get the following error message in my server logs:

> Nov 20 11:36:14 dev1 slapd[26783]: <<< dnPrettyNormal: 
> <cn=itadmin,ou=roles,o=mycompany>, <cn=itadmin,ou=roles,o=mycompany>

> Nov 20 11:36:14 dev1 slapd[26783]: send_ldap_result: err=21 matched="" 
> text="value does not conform to assertion syntax"

Any help resolving this would be greatly appreciated.

Thanks in advance.
