CAS protocol 3.0 How to enable cas as credential acceptor?

[casuser]

Dear All,

Good day!!!

Currently we are using CAS 5.3.8.

In the CAS protocol 3.0 section 2.2 it is mentioned that /login can be used as a credential acceptor.

2.2. /login as credential acceptor

When a set of accepted credentials are passed to /login, it acts as a credential acceptor and its behavior is defined in this section.

According to the protocol it accepts

• username [REQUIRED] - the username of the client that is trying to log in

• password [REQUIRED] - the password of the client that is trying to log in

• lt [OPTIONAL] - a login ticket. This is provided as part of the login form discussed in Section 2.1.3. The login ticket itself is discussed in Section 3.5.

• rememberMe [OPTIONAL, CAS 3.0] - if this parameter is set, a Long-Term Ticket Granting Ticket might be created by the CAS server (refered to as Remember-Me support). It is subject to the CAS server configuration whether Long-Term Ticket Granting Tickets are supported or not.

We have tried passing username & password to /login using a rest client but still we are being returned with the CAS login form.

How can we enable cas a credential acceptor.
