=head1 NAME

Authen::Smb - Perl extension to authenticate against an SMB server

=head1 SYNOPSIS

  use Authen::Smb;
  my $authResult = Authen::Smb::authen('myUser', 
                                       'myPassword',
                                       'myPDC',
                                       'myBDC',
                                       'myNTDomain');

  if ( $authResult == Authen::Smb::NO_ERROR ) {
    print "User successfully authenticated.\n";
  } else {
    print "User not authenticated with error level $authResult\n";
  }

=head1 DESCRIPTION

Authen::Smb allows you to authenticate a user against an NT domain.  You can
specify both a primary and a backup server to use for authentication.  The
NT names of the machines should be used for specifying servers.

An authentication request will return one of four values:

NTV_NO_ERROR (0)
NTV_SERVER_ERROR (1)
NTV_PROTOCOL_ERROR (2)
NTV_LOGON_ERROR (3)

NTV_NO_ERROR is the only return value possible for a successful authentication.
All other return values indicate failure, of one sort or another.

=head1 EXPORT_OK constants

  NTV_LOGON_ERROR
  NTV_NO_ERROR
  NTV_PROTOCOL_ERROR
  NTV_SERVER_ERROR
