Can't login to Lync for Mac 2011 I am unable to login to my corporate Lync 2010 server. I'm up to date with Microsoft updates to Mac Office 2011. I've tried automatic and manual configuration. I've tried with and without Kerberos authentication. I know I have proper credentials because I can login to the Windows version of Lync from a Windows session in Fusion.

Is anyone else using Lync for Mac 2011 on a corporate network? Anyone experience this issue and find a fix or a workaround?
I was able to resolve this issue in two steps. 


I imported the root certificate from my corporate Lync Server to my MacBook Pro and configured it as Always Trust(ed) for all options
I generated a kerberos ticket on my MacBook Pro using the terminal command kinit


The level of trust on the root cert maybe overkill, but it works. I have to regenerate the kerberos ticket periodically otherwise I am not able to sign-in to Lync, but I resolved this with an Automator app that runs the kinit command when I login to my MBP.

Hope this helps someone down the line. Cheers!
