[Samba] samba+ldap windows problem

[sermodi]

Hi everybody!
I don't know if this is a samba or ldap problem, so here is the problem and
you decide.
I've installed Samba+LDAP to replace the windows solution. The workstation
in the network are w2k so the need to logon to the samba+ldap for all the
setting to be fetched. The logon is working the only trouble is that I can't
get the option for changing the password, when I press the ctrl-alt-del, the
change password button is "unclickable". If I change the mustchangepasswd to
0 the the users are forced to change the password, it works. I just can't
get the changepassword button available. I have searched the web for days
and can't find a solution, Thanks
I have attached the smb.conf and slapd.conf
