Solution
Scan Center needs the ability to specify the "LDAP User ID Attribute" like Scan to Network can. In Scan to Network, if you enter an "LDAP Path Attribute", it will bring up a new "LDAP User ID Attribute" field.
Version 1.2.28.7 of Scan Center is available and allows an additional 'displayName' filter for entering a different value.
