I have been working with support on this issue, but they just gave me the canned answer of "upgrade to the most recent release and hopefully that will fix your problem".  I'm wondering if anyone else has experienced this issue:  

We are currently on version 10.1.0 (build 10100)

My primary instance is working perfectly.  In PMP, it shows that HA is active.  However, when logged into my secondary server, and I go to https://localhost:7272, I cannot log in.  If I use a local account, I get the following message "Invalid Username/Password".  If I attempt to log in using an Active Directory account, the PMP Service crashes and restarts itself.

When researching this issue, the database is able to talk to the domain controller and we can see the local account.  There seems to be something wrong with how the secondary installation is talking to the database.  Does anyone have any ideas of things we could look at to troubleshoot?  The program log files haven't shown anything helpful, neither have the server event logs, or sql logs. Or, maybe I just don't know what I'm looking for.
