i use samba 3_0_0 (from cvs) with ldapsam backend on FreeBSD 5.1.
i cannot change/delete user attributes (description,password, etc) if user
entry has a UTF8 dn:

# smbpasswd -x tiamat
could not delete attributes for cn=§á¡ö§á¨g§á¨k§ñ©°§á¨g§ñ©¤ §á░§á¨m§á¨g§á¨l§ñ©¦§á¨c§á¨o§á¨f§ñ©¤

failed to modify user with uid = tiamat, error:  (Protocol error)
Unable to modify entry!

in passdb\pdb_ldap.c used function dn = ldap_get_dn(...) that return UTF8
dn. Then call ldapsam_modify_entry (...,dn,...) -> smbldap_modify(...,dn,..)
in lib\smbldap.c:smbldap_modify dn converted from CH_UNIX to CH_UTF8 and dn
corrupted.

my smb.conf:

        dos charset = 866
        unix charset = KOI8-R
        display charset = KOI8-R

Thanks!
