Different domains for SAP Portal and Nakisa

Hello!

Could you please help me?

We have installed SAP Portal on SAP NetWeaver 7.01 and Nakisa Application on SAP NetWeaver CE 7.2.

So Nakisa and SAP Portal are hosted on different domains. We are going to use SSO2 authentication (using logon tickets), but SSO seems to donu2019t work between two different domains.

Can Nakisa be installed on SAP NetWeaver 7.01? If not, how can we configure authentication for Nakisa?

Regards,

Ekaterina
