We are setting up a new Pega Application with a Brand new client in Partnership with Pega. Our clients wanted to know if Pega 8.1 CRMI application support ADFS as SSO solution and will it support both IDP Initiated and SP-Initiated SSO. I tried to search, looks like it does, but since this goes in client documentation, I need to be 100% sure what I am committing.
I know you are looking for something official ect. I can tell you 100% we support IDP initiated request regardless of IDP being used. We have implemented SAML 2.0 per the specification. For IDP initiated requests we require a RelayState parameter to be provided along with the SAMLResponse to our AssertionConsumerService.
Regardless of IDP if there were issues on our end with IDP initiated requests we you would and an Support Request so we could investigate further.
