[Samba] how to set samba to force users to log off ??

[Hubert Choma]

Hello
I have samba PDC with tdbsam backend.
I set logon hours by usrmgr.exe utility from 8am to 4pm but I would like 
to samba force users to log off after 4PM because logon hours doesn't do 
it.
Is There any possibility without restarting smb nmb daemons to force 
users to log off??
Please reply .
Sorry for my English :)
