I guess I am missing something.

What is the purpose for this attribute and how should it be maintained?

If a user is renamed in AD, by the AD driver or not, should the value of
the DirXML-AdContext be updated?

Likewise if a user is moved in AD, by the AD driver or not, should the
value of the DirXML-AdContext be updated?

Any recommendations on how would also be helpful.

Thanks
