Logon ticket creation in EP6

Hi.

I want to SSO with SAP R/3 BSP application in portal.

My EP use Own Database for UME.

I configured some stuf for accepting logon ticket in SAP R/3 (I read document that EP create logon ticket at default) but SSO doesn't work.

So, I trun on checking cookie in browser and I logon into EP. (Just login)

When I logon EP, There is no cookie sent to browser.

Do that mean EP doesn't create login ticket ?

Any idea ?

Regards, Arnold.
