    Good morning,

    After upgrading to Adium 1.5.10 and SIPE 1.18.2, I can no longer connect to our Office 365 Lync 2013 service. I receive the following error when attempting to connect: "Error: Web ticket request to https://webpoolsn20b06.infra.lync.com:443/CertProv/CertProvisioningService.svc failed"

    I've attempted utilizing both the Lync 2013 and Lync 2010 user agents to no appreciable effect. I've included some of my other settings below:

    Server: sipdir.online.lync.com:443
    Connection Type: SSL/TLS
    Authentication scheme: TLS-DSK
    User Agent: UCCAPI/15.0.4481.1000 OC/15.0.4481.1000 (also tried UCCAPI/4.0.7577.314 OC/4.0.7577.314)
    Use Single Sign-On: Disabled
    Disable BEAST mitigations: Disabled

    Regards,
    -Sean Hansell
