Re: RPG program - Kerberos Authentication

Sorry probably I forgot to mention this earlier, I already got the GSS API documentation from IBM website but it looks like to enable Kerberos authentication it requires client and server components.
In case of logging into IBM i server, 5250 emulator running on client PC acts as the client component, communicates with KDC and gets the Kerberos service ticket which is then passed on to the IBM i server

As our application is RPG based green screen application we don’t have any client component running on every local PC so I am trying to understand how to connect to KDC and get the service ticket for our application

You could either invoke Java methods or - more efficiently - find the

Subject: RPG program - Kerberos Authentication


We have RPG based application running on IBM i and it has its own user

authentication module based on username and password, we want to enable
Kerberos authentication for our RPG green screen application. Are there any
references on how to obtain Kerberos Service Ticket using RPG program

Please note we have already enabled Kerberos authentication for IBM i

server login using NAS and EIM setup. As our product customers won’t have
separate IBM i user profile for each user (shares same IBM i user profile
for all users) we are trying to map the windows domain username which is
unique for each user to our application username
