samba - Sep 2003 - smbpasswd > sync passwd Please help me

Hi all,

I have the following Problem.

I use samba 3.0 rc2.

A user is not able to change the password on an w2k workstation. There comes the
following message: YOU HAVE NOT the permission to change the password.
A user who is in the root group can change the password and  the smbpasswd is
syn with the passwd.
The same problem occures with samba 2.4, 2.5, 3.0 beta and rc1.
depends this problem of the dictionary check of the passwords? How can i turn
off this feature of UNIX? I have RedHat 9.0.
Here is my smb.conf:

[global]
        log file = /var/log/samba/%m.log
        smb passwd file = /etc/samba/smbpasswd
        passwd program = /usr/bin/passwd %u
        encrypt passwords = yes
        passwd chat = *New*password* %n\n *Retype*new*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully.*
        passwd chat debug = yes
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        admin users = @domainadm
        logon drive = u:
        domain master = yes
        interfaces = 10.17.1.2
        hosts allow = 10.17.1. 10.17.2. 10.17.3. 10.17.4. 10.17.5. 10.17.6.
10.17.7. 127.
        time server = yes
        preffered master = yes
        password level = 0
        netbios name = Turm
        server string = Navy Seals PDC
        logon script = logon.bat
        unix password sync = yes
        local master = yes
        logon path = \\%N\%u\profiles
        workgroup = babel
        os level = 33
        add user script = /usr/sbin/useradd -d /dev/null -g machines -s
/bin/false -M %u
        security = user
        domain admin group = @domainadm
        max log size = 50
        domain logons = yes
        log level = 100

Thanks.
