We are using EP6 SP09 with ECC 5.0. I am creating several SAP transaction iviews using the integrated ITS componment. However, we are unable to achieve single-sign on with this integrated ITS.
When you create the SAP transaction iview, the iview will load a <i>"Invalid host name for issuing SSO ticket"</i> screen asking you to login. However, when you logon to the application the transaction loads.
Are there additional configuration needed in ECC? We have activated the service for ITS > Webgui in the transaction SICF.
for this problem u have to configure u r SAP ECC system by making use of STRUSTSSO2 t.code
when u execute this t.code it asks for Verify.der and verify.pse file which has to downloaded from portal server.
the details about this S.S.O is given in this link
SAP AUthneitcation SSO....
let me know u r problem is solved or not
