<p>This function requests KDC for an initial credentials for <em>client</em> using <em>password</em> . If <em>password</em> is NULL, a password will be prompted for using <em>prompter</em> if necessary. If <em>in_tkt_service</em> is specified, it is parsed as a principal name (with the realm ignored) and used as the service principal for the request; otherwise the ticket-granting service is used.</p>
