Dont know if anyone has seen this behavior.  In the NCM plugin we have our devices set to monitor for change management through the syslog.  We typically go in and mark unauthorized changes (changes made outside of the NCM) as authorized in a review period.

 

The NCM module will kick the user out and go back to the login interface for OpManager after authorizing three dates.  You can sign back in, do three more and it will kick you out again.

 

I am using the latest version of both OpManager and the NCM plugin, along with IE9 as my browser.  I am going to try a different browser to see if I get the same results.
