GLPRDB020E
Entry entry DN cannot be modified.
Explanation
The LDAP server cannot complete the request because
the original entry does not use an object class that indicates
that it contains Enterprise Identity Mapping (EIM) information.
However, an object class that indicates that the entry will contain
EIM information was specified on the modify request. If an entry
originally does not specify an EIM object class, an EIM object class
cannot be added to the entry at a later time.
User response
Modify the request so that no EIM object classes are
being added to the entry and try the request again.
