Stop the Winbind and Samba services:
    service winbind stop
    service smb stop

Clear the Samba Net cache:
    net cache flush

Delete the Winbind caches:
    rm –f /var/lib/samba/*.tdb
    rm –f /var/lib/samba/group_mapping.ldb

Start the Samba and then Winbind services - Note: The order is important
    service smb start
    service winbind start
