Extra accounts in 9200?

Hi everyone,

I recently upgraded my OpManager to the new 9.2 service pack that was released. While looking around at some of the features, I noticed that under the User Manager, we suddenly have three extra accounts that were created named "nadmin," "sadmin," and "vadmin." I assume the names are referencing different types of monitored equipment (network admin, system admin, and virtual admin, respectively), however this is not something that was set up by either me or my sysadmin - currently the only two people who use the service.

Is this something that was added by the 9.2 service pack? Or should I just delete them?

Thanks.
