Skype For Business user unable to login RRS feed

  • Question

  • Hi,

    We are facing strange issue with one of our domain. the domain users have recently been migrated to Skype for business Online. After migration, they are not able to login to Skype client on every machine except their domain joined machines. Upon reading the Snooper traces, I find these lines to be suspicious:

     Error:
    The server returned a trust fault: 'The specified request failed'.
    The fault reason was: 'The SIP URI in the claim type requirements of the web ticket request does not match the SIP URI associated with the presented credentials.'.

    I ran Skype for business Server Remote Connectivity test but that too failed with following error:


    Couldn't sign in. Error: Error Message: No common authentication method detected..
    Error Type: AuthenticationException.
    Error Code: 0.
    Realm: SIP Communications Service.
    Response Code: 401.
    Response Text: Unauthorized.

    Could you provide suggestions what I could check?

  • O365 uses specific set of certificate which must be installed on all workstations so that it can communicate over TLS. You can compare the trusted certificates on a PC that client works and the one that have issues. Also, this could be related to ADFS authentication. You can try browsing to the SAFS URL and see if the sign in process goes through fine from that PC.

  • You should call office 365 support.. there is a policy in Office 365 to not allow login except from the domain joined machine.
