I have an attribute that I want to do a DN *like* lookup on similar to manager. The attribute lists a value that cooresponds to a value on another user, but it is not their DN. How might I configure that?

For example:
User A has a value of sponsor that is: A3DE43Q

User B has a value of myID of: A3DE43Q

User A should display user B as a sponsor just like a manager would appear.

It would appear the DN lookup area won't work for this, how might I go about handling this?

Thanks in advance!
