NAME

DTS::Credential - credentials to authenticate against a MS SQL Server 2000

SYNOPSIS

use DTS::Credential;

# regular authentication method
my $credential = DTS::Credential->new(
    {
        server                 => 'somedatabase',
        user                   => 'user',
        password               => 'password',
        use_trusted_connection => 0
    }
);

#trusted authentication mode

my $credential2 =
  DTS::Credential->new(
    { server => 'somedatabase', use_trusted_connection => 1 } );

DESCRIPTION

DTS::Credential implements the authentication scheme expected by MS SQL Server connection depending on the mode that will be used (regular authentication or trusted connection).

This class was created to be able to invoke the DTS Application LoadFromSQLServer (and others) method in a polymorphic way, since these methods expect a lot of parameters given in the correct order (some parameters are even unused, but one must inform them anyway).

One should not need to use this class directly: it is used by the DTS::Application module and, if you're using this class there is nothing to worry about authentication.

EXPORT

Nothing.

METHODS

DTS::Credential does not inherients from any superclass. This means that the methods available in DTS are not available.

new

This method creates a new DTS::Credential object. A hash reference must be passed as a parameter (see SYNOPSIS for examples).

Depending on the authentication method, user and password are necessary or not. The Trusted Connection does not need such values, but the new method will abort with an error if you pass no keys with the necessary values.

A DTS::Credential object will have the following attributes:

  • server

  • user

  • password

  • auth_code

auth_code is defined by the DTS Application object documentation to be defined as explained below:

  • Constant DTSSQLStgFlag_Default = 0

  • Constant DTSSQLStgFlag_UseTrustedConnection = 256

to_list

Returns all attributes of the object in a ordered list. This will be used during method invoking to authenticate the request against the MS SQL Server. The list is returned in this order:

1 server
2 user
3 password
4 auth_code

  • Win32::OLE at perldoc.

  • MSDN on Microsoft website and MS SQL Server 2000 Books Online are a reference about using DTS' object hierarchy. You will need to convert examples written in VBScript to Perl code.
