One ADMIN group user may connect to FairCom DB when the maximum number of authorized users limit is reached. One client belonging to the ADMIN group can log on to a server, even if the maximum number of connections is used, by setting the USERPRF_ADMSPCL bit of the user profile.
This capability allows the Server Administrator to perform administration tasks even when the server is at its maximum licensed connections. The ctadmn and ctstop utilities take advantage of this feature.
