[rbak-nsp] Re-authorize subscriber via snmp

[serstor]

HI!
Which way I must  configure RedBack to make re-authorize work's via 
snmp.  I do snmpset -v2c -c community_word at contex Redback_IP 
.1.3.6.1.4.1.2352.2.27.1.1.3.7.0 s "username" . Result:  
SNMPv2-SMI::enterprises.2352.2.27.1.1.3.7.0 = STRING: "username". RADIUS 
returns new value of Sub-Profile-Name to RedBack, but nothing changes in 
active session of user.
