During configuration of Web Portal autologin in CA PAM as a TCP/UDP service with autologin methods it is only possible to use the CA PAM browser.
However, it turns out certain portals will not allow learning mode to progress or- even worse- will not display the correct information when the CA PAM browser is used to connect to them. Typically a blank background window may be displayed. Login via native browser or outside PAM works just fine, only that then autologin may not be configured and neither can session recording.
CA PAM all versions up to 3.2.2
