Hello,
when using pam_smbpasswd only an empty password with XXX is created in the 
smbpasswd file when using the migration function. (With samba 2.2 this was OK).
If have fixed this in changing the following line in pam_smb_auth.c (Function 
_smb_add_user)
---------------------------
        retval = local_password_change( name, LOCAL_ADD_USER,
                                         pass, err_str,
                                         sizeof(err_str),
                                         msg_str, sizeof(msg_str) );
---------------------------
to 
---------------------------
        retval = local_password_change( name, LOCAL_ADD_USER | 
LOCAL_SET_PASSWORD,
                                         pass, err_str,
                                         sizeof(err_str),
                                         msg_str, sizeof(msg_str) );
---------------------------
Now the correct password entry is created in the smbpasswd file.
Is this modification OK?
