SSO is not working

Hello Guys,

We have some issue with our portal system. SSO is getting failed from portal to backend ECC system.

I have checked all the settings of portal as well as ECC system and everything is seems to be working fine to me.

What is most surprising is that we have another portal and ECC system and SSO is working fine there with same set of parameters.

I have one doubt that in first case we have portal and ecc server in different domain? So is there any specific settings for this?

Any help will be appreciated.





Yes. Normal SSO settings will not work when your portal and backend system are not in same domain.

The reason behind is that SSO ticket issued by portal will expire when this reach to the backend system is another domain.

So you use one web server in your another domain so that portal sends SSO ticket to web server and this server will pass ticket to your backend server and this will work in this way.

Refer to below link.


With Regards,
