[Samba] ldap passwd sync problem with slave ldap server

[tisdn tisdn]

Hello everyone!
I'm having problem with the parameter ldap passwd sync = yes. If my ldapsam
points to a master ldap server, it works perfectly. If it points to a slave
ldap server, the samba attributes are update but not the userpassword.
I'm using samba 3.4.3 with Fedora Directory 1.2.

Viewing the log files I saw same strange messages when I trying to change my
password:

[2009/12/08 15:10:42,  5] passdb/pdb_ldap.c:ldapsam_modify_entry(1660)
  ldapsam_modify_entry: mods is empty: nothing to modify
[2009/12/08 15:10:42,  2] passdb/pdb_ldap.c:ldapsam_update_sam_account(1961)
  ldapsam_update_sam_account: successfully modified uid = test in the LDAP
database

Thanks,
TISDN
