Thanks David.

Finally I reserved the machine for the testing,

	[root@...dl360-01 ~]# keyctl request2 user debug:a b @s
	623133085
	[root@...dl360-01 ~]# keyctl show
	Session Keyring
	       -3 --alswrv      0     0  keyring: _ses
	845914766 --alswrv      0    -1   \_ keyring: _uid.0
	623133085 --alswrv      0     0   \_ user: debug:a
	[root@...dl360-01 ~]# keyctl print 623133085
	Debug b

Hopefully this all is right.

Oleg.
