Thanks Christian! You got my question right!
From you explanation, Understand if it unix/linux or Windows sever devices, we need
IP Address:Host Name:
Connection method/protocol:
If yes to Auto-login credentials:
etc...
Likewise, what information (most common ones) for other devices/endpoints types like portal, AWS, Network devices, Federation(SAML consumer) etc... are required to configure in CA PAM is what i am attempting to understand.
