--------------------------------------------------------

It's look like smbpasswd try to find already exist user.
But "-a" is "add user". I think it must create account.
And if I set ldap filter in smb.conf  - 
"(&(uid=%u)(objectclass=sambaSamAccount))", i have a message (Bad filter)

Have anyone some idea?
