working proprerly.The main message of this problem "The authscheme

found in the ticket does not exists".

The main problem here is the iview that need to show the userid logged

into portal is Z106708 but shows J2EE_GUEST.

Any clue to resolve this issue ?

This autscheme uidpwexpirenowarnings (name has to be the same) should exists in both of systems(Portal and STACK Java).

Hope this helps

Hi Jakub,

How can I install this module ? The Portal side is located in Germain and I have the WAS here in Brazil trying to use SSO authentication. Where and how can I check this schema ?

Celio,

You need to use the SAP Config Tool, to download the authschemes from the SAP system, edit the xml file you downloaded, and then upload the new file. For testing I suggest you rename the file and upload with different name (and make sure SAP knows which authschemes you want to use), then if you find you made a mistake you can easily get back to the original authscheme configuration.

When you edit the xml file you downloaded, you need to add a new authscheme to this file called uidpwexpirenowarnings, with the correct configuration (same as on the Portal).

If you are not sure what the authscheme uidpwexpirenowarnings should look like you need to ask your friends in Germain (Germany ?) how they have configured the authschemes in their Portal.

You can find details of above mentioned Config Tool in SAP Help Library, e.g. some info at [this location.|http://help.sap.com/saphelp_nw04s/helpdata/en/1a/3afd4e641b8f42ac07bb77fe30375b/content.htm]

Thanks,
