If you were using smbpasswd as the passdb backend, note that the default 
changed to tdbsam in version 3.4.0.

To continue to use smbpasswd, you would have to declare it in smb.conf.
     passdb backend = smbpasswd.

You could also export your existing smbpasswd to tdbsam.

        Account Import/Export

The |pdbedit| tool allows import/export of authentication (account) 
databases from one backend to another. For example, to import/export 
accounts from an old |smbpasswd| database to a /|tdbsam|/ backend:

   1.

      |root# |*|pdbedit -i smbpasswd -e tdbsam|*

   2.

      Replace the /|smbpasswd|/ with /|tdbsam|/ in the /|passdb
      backend|/ configuration in |smb.conf|.
