P6 8.1 SP1 Optional Client receives the following error message: <user name> is already logged in at

I upgraded my 8.1 Optional Client to connect to a development PMDB with SP1. Now after I log in once with any user name I receive the message that "<user name> is already logged in at Terminal <machine name> under Windows Login account <user name>. Do you want to clear this user?" If I select Yes, the login is cleared and I am able to enter the PMDB. I'm concerned that this is similar to the USESSION issue from previous releases. 

During our upgrade from v7.0 SP2 to 8.1 on our production PMDB, the DB was over-privileged and the USESSION issue was a problem as was a non-commitment of deleted data in P6 (relationships, activities, etc.). Before the over-privileged issue was found, Oracle provided two lines for us to add to the PM.ini file which gave the end-users the ability to clear out the locked user session themselves. Otherwise, our DBA would need to clear the sessions on the production SQL server.
