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:
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
My apologies, I just noticed the thread at: https://sourceforge.net/p/sipe/discussion/688534/thread/bfc55184/
This answers my question, I believe. Please disregard.
