[Samba-it] ldap+samba gli utenti non possono cambiare la loro password

[alphac]

Ho un problema con samba ed ldap, sembra che l'utente non riesca a
cambiare la propria password,
ecco i comandi che do:
(net rpc password myuser mypw -U myuser) o da windows con (ctrl+alt+del).
Ottengo un errore di timeout:

[2006/03/16 21:52:40, 0] rpc_client/cli_pipe.c:rpc_api_pipe(790)
  rpc_api_pipe: Remote machine alphacserver pipe \samr fnum
0x70e9returned critical error. Error was Call timed out: server did not
respond after 10000 milliseconds
[2006/03/16 21:52:40, 0] libsmb/clientgen.c:cli_rpc_pipe_close(375)
  cli_rpc_pipe_close: cli_close failed on pipe \samr, fnum 0x70e9 to
machine alphacserver.  Error was Call timed out: server did not respond
after 10000 milliseconds

from samba (loglevel 3) logs I see:

  smbldap_open: cannot access LDAP when not root..

from ldap (loglevel 256+128)

slapd.conf acl :

access to attrs=userPassword,sambaLMPassword,sambaNTPassword
      by self write
      by anonymous auth
      by * write
access to *
      by self write
      by anonymous auth
      by * write

Ho messo in slapd.conf accesso in scrittura a tutti per scongiurare
eventali configurazioni errate ma non cambia nulla, sembra che l'errore
sia di samba, ho provato con la 3.0.14a 3.0.21c di debian tutte hanno lo
stesso problema...

Avete qualche idea?

grazie
