my smb.conf:

     security = ADS
     realm = QIANW.COM
     encrypt passwords = yes
     idmap config *:range = 16777216-33554431
     winbind trusted domains only = no
     winbind use default domain = yes

     winbind refresh tickets = yes
     template shell = /bin/bash

     log file = /var/log/samba/%m.log
     log level = 5

any ideas on this issue?

Thanks.
