Configure SSO SAML with SAP IAS ADFS and S/4HANA Cloud... relaystate problem with SAML

2880 Views


Hello,

We are cofiguring the SSO SAML in the clients SAP IAS (SAP Identity Authetication Service - xxxxxx.accounts.ondemand.com) using a Corporate Identity provider (ADFS) to connect to a S/4HANA Cloud (https://myxxxxx.s4hana.ondemand.com).
We are having problems with the parameter RELAYSTATE. in the IAS it has a ID "ouc....." but when it sends it to the ADFS, the ID changes (ARC.....). When it comes to the S/4HANA Cloud, it gives us an SAML error page "SAML2 service not accessible" (No RelayState mapping found for RelayState value arcd48a0f).
We have in the ACS URL: https://myxxxxxx.s4hana.ondemand.com/sap/saml2/sp/acs/100

We have looked help.sap.com & blogs and we havenn't seen any way to disable or to bypass the relaystate problem. How can we bypass it?

best regards,..
