(RADIATOR) user hanging in radonline

Hello Indrajaya Pitra Perdana -

When you enable the NasType parameter in your Client clause(s),  
Radiator will automatically manage the session database as you  
describe below.

If a stale entry is left in the session database, Radiator will check  
the NAS via the method described in section 5.5.5 of the Radiator  
3.16 reference manual ("doc/ref.html"). If the session has  
disappeared from the NAS, Radiator will remove the stale session from  
the session database and allow the new connection to proceed.

hope that helps

regards

Hugh
