Hi everybody,
I'm an italian system administration (newbie about Samba).
I have installed on Mandrake 9.1 the rpm samba3-*-3.0.2a downloaded from 
a Samba.org's mirror.
I have configured a PDC based on ldapsam (OpenLDAP 2.1.29) that works 
fine, i use smbldap tools to manage sincronization account.

Now the problem, when I try from my W2000 Workstation to change my 
domain password I reach a error message:
UserName or Old password are wrong....Obviously these are right, not wrong.

Analizing samba log this is the message that I found:
[2004/04/15 12:07:29, 0] smbd/chgpasswd.c:check_oem_password(832)
  check_oem_password: incorrect password length (1211185023).

My old password is of  7 chars, the new of 8 chars but I have the same 
problems with password of other lengths, less and more.

If I try to change the password with:
smbpasswd -U <username> -r <PDC> i get this message on video

machine <PDC> rejected the password change: Error was : RAP86: The 
specified pas
sword is invalid.
Failed to modify password entry for user <username>

This is the section of Samba's log about this operation
[2004/04/15 12:40:00, 2] passdb/pdb_ldap.c:init_ldap_from_sam(769)
  init_ldap_from_sam: Setting entry for user: <username>
[2004/04/15 12:40:00, 1] passdb/pdb_ldap.c:ldapsam_modify_entry(1217)

uid=<username>,ou=Users,dc=usl11,d

dify/delete: sambaPwdMustChange: no such value (Success)
[2004/04/15 12:40:00, 2] smbd/server.c:exit_server(558)
  Closing connections

Obviously the sambaPwdMustChange attribute is one of the entry, it's 
value has no sense for me but it's present.



This is a section of my smb.conf :

Please, help me...
