Hi,
me and my colleagues are facing a minor problem with Office Communicator during VPN sessions.
Our OCS enviroment is "hosted" in one of our DMZs and has its own forest. So a different domain-name from our internal and the SIP-Domain. All users / devices intern and extern connect via Edge Server. Communicator credential saving is allowed via group policy.
If someone is successfully connected using the UPN in its credentials like: jsmith@domain.com and switch into VPN (ISA server) Communiator will disconnect and all reconnection attempts fail. Changing the Logon to SAMaccount name like: dmzdomain\jsmith will connect Communicator immediately.
Intern and extern we can use UPN, only in VPN it fails.
What might cause this behavior? Has anyone an idea how to fix it? Thanks in advance.
Best regards,
Jan
