Seems like something wrong with device. It gets correct attribute but works incorrectly. means that user get monitor rights
arg[0] = [13][role1=MONITOR]
*tplusTransportThread: Oct 25 10:26:08.147: User has the following mgmtRole 4
User has the following mgmtRole 4 <-- means that user get monitor rights
LOBBY = mgmtRole 2
WLAN = mgmtRole 8
CONTROLLER = mgmtRole 10
WIRELESS = mgmtRole 20
SECURITY = mgmtRole 40
MANAGEMENT = mgmtRole 80
COMMANDS = mgmtRole 100
mgmtRole also can be combined, e.g. role1=CONTROLLER role2=WIRELESS equal to mgmtRole 30
Hope it helps.
