Redirecting To Another Portal From Appian Site

Hi Hitesh,

It depends on what kind of site the "external portal" is exactly. It sounds like you are trying to implement an external authentication system (external portal) that you want to integrate with Appian?

If that is the case, Appian is supported to work with SAML and LDAP:
forum.appian.com/.../SAML_for_Single_Sign-On.html
forum.appian.com/.../LDAP_Synchronization.html

Where in this case, your "external portal" is the identity provder (IdP).

If your focus is on keeping the "session context" of your external portal active, you may be interested in using an embdedded interface to give users "access and control" to your Appian environment, while staying within your external portal.

Hi,

We are not looking to use Embedded Interfaces. Idea is to use an external portal which will then initiate an IDP SSO into Appian Sites. Once the user is working on Appian Site, he should have the capability to go back to the external portal from where the journey started initially. So the questions are:

1) What is the best way to provide an option to the user to navigate back to external portal?
2) How can the session for the external portal be kept alive from Appian end? Where can we put the logic to keep the external portal live in Appian, probably by hitting 'Keep Alive' url for the external portal but where can this be embedded or configured?

Thanks.
Hitesh
