The credentials used by the SCOM Management Pack are not for accessing the Orion web interface, but for the Orion API, which does require administrator level permissions to access. This is really no different than the permissions required for using the Orion SDK.
Is there a Management pack for Vman to Scom in particular. ?
Also how about other Modules of Solarwinds will they be supported and does it work with SCOM.?
