Hello Lei
I am logged into Windows as sidadm. When I run xuser list I get :
XUSER Entry 2
--------------
Key :c
Username :CONTROL
UsernameUCS2 :C.O.N.T.R.O.L. . . . . . . . . . . . . . . . . . . . . . . . . .

Dbname :SID
Nodename :dsimsid001
Sqlmode :INTERNAL
Cachelimit :-1

as part of the output. So it seems that all is well with the c xuser key.
