Can't connect to Office Communication Server through Unified Communications API
- by Robin Clowers
I am trying to connect to Office Communication Server using the Unified Communications Managed API. I have tried my user and a fresh user enabled for OCS. Both account can successfully log into the Office Communicator client, but fail using the API. When creating the network credential, if I pass in the username in the form domain\username, I get this error:
SupportedAuthenticationProtocols=Ntlm, Kerberos
Realm=SIP Communications Service
FailureReason=InvalidCredentials
ErrorCode=-2146893044
Microsoft.Rtc.Signaling.AuthenticationException: The log on was denied. Check that the proper credentials are being used and the account is active. ---> Microsoft.Rtc.Internal.Sip.AuthException: NegotiateSecurityAssociation failed, error: - 2146893044
If I leave off the domain in the username I this error:
ResponseCode=404 ResponseText=Not Found
DiagnosticInformation=ErrorCode=4005,Source=OCS.mydomain.com,Reason=Destination URI either not enabled for SIP or does not exist
