ldap_modify_s Insufficient access

[Thorsten D. Marsen]

Hi, we are running Samba 2.2.5 using LDAP und pam_ldap (pam_unix2 with auh+account+password=use_ldap) as PDC out of the SuSE 8.1 distribution. It runs very well: Login für Unix&Samba ok, Passwort-Change for Samba via smbpasswd Ok and we are able to manipulate the Linux Password in LDAP using the GQ Client. The only thing that doesn't work is passwd itself:

venezuela:/home/tdm # passwd guest
Changing password for guest.
Enter login(LDAP) password:
New password:
Bad password: a palindrome
Re-enter new password:
LDAP password information update failed: Unknown error

Password changed
venezuela:/home/tdm #

and in /var/log/messages:
Jan 28 13:39:47 venezuela passwd[28505]: pam_ldap: ldap_modify_s Insufficient access

Thanks in advance,
Thorsten.
