In my lab I have one computer that is a member of some un-trusted domain. Communicator, certificates and cert-chain are installed on it and I can logon to the OCS-featured domain over TLS-transport.
Right now after each successful logon I get the Communicator - Services Sign In dialog with the User name and Password fields. Each time I press [Cancel] to skip the dialog.
What is the purpose of the dialog box? Outlook-integration related?
