Error with logon after linking to portal from corporate intranet

[Former Member]

We have a corporate intranet running on the same WAS system as our Enterprise portal. We use JCIFS authentication on our corporate intranet and an ABAP backend for our Portal. We would like to create a link from the intranet to our portal (http://was.corporate.com/irj/portal). The link comes up just fine, however when we attempt to logon, the USERID field (regardless of what we type in) is delivered to the system as null. The security logs indicate that USERID=null. We are able to do this when opening the link from another server (example: Intranet = http://server1.corporate.com and portal = http://server2.corporate.com/irj/portal) but when we try to open it from the same physical box we get a UserID=null error. We are on WAS640 SP14. Has anyone else experienced a problem like this?

Since you are on the same physical box, I suspect that you are over-writing the cookie with the SAP logon ticket (MYSAPSSO2), and so losing the user id. You could use an HTTP trace tool to verify that (e.g., HTTPWatch, or the free iehttpheaders).

If that is the case, a possible work-around would be to use virtual hosting (see the SAP documentation) so that you have two web server names for the same box. Then the cookies won't collide, as the cookies are specific to the host name in the HTTP request.
