Lync sign-in failing

Hi again, after some tests I found that this issue is not appearing when ssl persistence (set by default in iApp template) is not used and source IP persistence is used instead.

I all the time though that SSL persistence just read SSL session ID and store it localy on LB memory, but now it seems that it has some impact to the traffic flowing through LB VIP. Have anybody seen something like that?

Thanks, Zdenek
