Question

I am writing a Delphi application that allows a user to connect to an AIX system to perform various tasks.

I need to allow a user to sign on to the AIX system before they are allowed to do anything, so I need a method by which their username/password can be authenticated.

I had initially thought that I could display a sign on screen where they would enter their username and password, then establish an FTP connection (or Telnet, or something similar) with the AIX system, but this would not be a reliable method as the functionality may be locked down (eg. FTP port blocked etc.) which would obviously result in a failed sign on despite the username/password credentials being correct.

The bottom line is this: How can I authenticate a user’s username/password against an AIX user account by using Delphi? A colleague suggested that using SSH might work, but I suppose I’d need a 3rd party component for that (if one exists). I am using Delphi 2009 Pro.

AIX supports Kerberos, you only need a Kerberos client for Delphi.

How can I get a Kerberos ticket with Delphi?

Kerberos (pronounced /ˈkɛərbərəs/)
is a computer network authentication
protocol, which allows nodes
communicating over a non-secure
network to prove their identity to one
another in a secure manner.
