Problem Changing Windows Passwords

[Martinez, Alfredo]

Hello,

I have Samba running on SLES 10 with a single Windows XP PC joined onto the domain. Users can login fine - though they are unable to change their passwords from within the Windows environment, returning the error: "Cannot change user's password at this time, Permission Denied". This only happens here, as we are able to run smbpasswd on the Linux side on any user and successfully change their password in this way.

Is this a passwd chat problem with SLES10? If so, what is the proper syntax?

If not, is there something that I am missing here? I've pasted my smb.conf file if it helps any.

Any and all help is appreciated.
