SSO JCO Connection to ECC fails

Hi there,

I was able to succesfully setup a BICS connection via SSO to a SAP BW system. I followed these instructions:

http://wiki.sdn.sap.com/wiki/display/BOBJ/Setup+of+SSO+againt+SAP+BW+for+SAP+BO+BI4.0+BICS+or+JCO+connections

Unfortunately, I was not able to configure a JCO connection via SSO to a ECC system. There are a few lines mentioned regarding the JCO connection in the previously mentioned wiki articles but I wasn't able to establish a connection. The error message says: "No user/password" but no additional information.

Is there maybe something missing in this article? How can I further debug this issue? Any ideas?

Thanks a lot in advance for your comments!

Best Regards,

Joerg
