问题
I configured IBM WebSphere Portal 6.1 on WAS7: SPNEGO, ssl with self signed certificate, default http transport (without Web Server) and changed default ports 10039, 10029 to 80, 443. After that SPNEGO works fine on http, on https displayed standard login form. Where there may be a mistake?
回答1:
Did you take a look at this document: WebSphere Portal Windows SSO w/SPNEGO
Mapping the user to the Kerberos Service Principal Name (SPN) When you run the setspn and the ltpass commands there should be something else that points to HTTPS.
Maybe you need another SPN account for HTTPS.
Good luck.
