Samba and Unix Password Sync


I'm trying to activate Unix Password Syncing in Samba (Distribution: Sarge).
However, it doesn't work:

thomas@gucky:~$ smbpasswd
Old SMB password:
New SMB password:
Retype new SMB password:
cli_pipe: return critical error. Error was Call timed out: server did not
respond after 20000 milliseconds
cli_oem_change_password: Failed to send password change for user thomas
machine rejected the password change: Error was : Call timed out:
server did not respond after 20000 milliseconds.
Failed to change password for thomas

If I deactivate the syncing in /etc/samba/smb.conf, Samba works without
problems - also changing the password is no problem.

Another (perhaps related) problem:
After the failed attempt to change the password (as above), the Samba demon
isn't stopped by its init.d script anymore:

root@gucky:/etc/samba# /etc/init.d/samba stop
Stopping Samba daemons: nmbd smbd.
root@gucky:/etc/samba# ps axu | grep sm
root      4131  0.0  0.5  9604 3072 ?        S    15:03   0:00 /usr/sbin/smbd -D
root      4146  0.0  0.1  3236  712 tty1     S+   15:04   0:00 grep sm

There's no .pid file in /var/run/samba anymore. If I restart Samba, netbios-ssn
doesn't listen anymore:

root@gucky:/etc/samba# /etc/init.d/samba restart
Stopping Samba daemons: nmbd smbd.
Starting Samba daemons: nmbd smbd.
root@gucky:/etc/samba# netstat -a | grep netbios
udp        0      0 dhcp31-240.p:netbios-ns *:*
udp        0      0 *:netbios-ns            *:*
udp        0      0 dhcp31-240.:netbios-dgm *:*
udp        0      0 *:netbios-dgm           *:*

To get Samba back to working, I need to kill the demon manually.

Any ideas?
