Customize SAML with 2 differents types of id

[gusalex]

Hi Colleagues,

we customized SSO login to SAP Fiori launchpad.

We started with email that is customized to get it from field ALIAS in SU01 user data. It was working fine.

Then, we wanted to customize another type of SSO with a userid also customized in field ALIAS in SU01 user data.

Apparently, we cannot use both customizing:

• if I set email by default in SAML customizing, then user with userid cannot logon
• if I set userid by default in SAML customizing, then user with email cannot logon

So, what we need is to allow SSO logon if user as email or userid.

Do someone knows how to customize that ?

Thanks,

Alex
