We have portal installed on domain portal.domain.com and ECC installed in ecc.domain.com.
SSO works absolutely fine between portal.domain.com and ecc.domain.com when portal is accessed using http://portal.domain.com:50000/irj
Due corporate policies we have to change the portal url to portal.corp.com instead of portal.domain.com. Everything work but SSO between Portal & ECC is broken.
I understand that SSO is broken because SSO doesn't work with multi domains.
Due to network complexity we cannot assign alias to the ECC server.
Has anybody had this situation and how was it fixed. How to achieve SSO when portal and ECC are in different domains.
Thanks in advance.
