I would like to have the portal users who logged into the company network will access portal with no sign-on.
To achieve my goal, I think I have a couple of ways of implementation:
1. Use CA SiteMinder for user authentication of portal. Question 1: do I need to have a web server for SiteMinder web agent in front of portal? Can the web agent be installed directly on the NW WAS where portal installed?
2. Use Integrated Windows authentication on portal. Question 2: I will definitely need a web server in this case, am I right?
Question 3: if I use CA SiteMinder as user authentication in portal, then what UME (e.g. LDAP, Portal UME, or ABAP UME) is not matter, as SiteMinder will handle it via HTTP Header, am I right?
Question 4: I read about the history discussion, it seems there is an issue for portal admin to login, do content admin, system admin, user admin if use SiteMinder. What is the solution for it?
Thanks in advance.
