Our network has several trees. GWIM is installed in our main tree with
the Messenger system in its own container (since we want only IM users to
be able to be viewed my the messenger clients). For our users from the
same tree, we use aliases so their IM password will always be the same as
their network password. For IM users from other trees we create a user
object in the container.

My problem is this: As long as I run GWIM 1.0.0 everything is fine. If I
apply a service pack ... the aliases can no longer be searched or added
to the contact lists. Users can still log in using their alias, but they
cannot be found by other users. I have also tried creating new aliases
after the upgrade and they have same fate.

Anyone got a solution for this?
