Currenty I am trying to configure SSO for Mytimesheet application. In our company in ADFS can have 12+ symbols Name IDs but SAP supports user with max length 12 symbols. We use FM that during RSLDAPSYNC_USER transform user ID (for example 'sapcommunitynetwork' will be transformed to 'sapcommunit1'). I already configured SSO by guide (Overview of SSL + SAML 2.0 Configuration) but it doesn't support situation when person want to login with user ID 'sapcommunitynetwork' which doesn't exist on Fiori side. And the issue is that system should support SSO for both type of users.
Have anyone faced same situation and know any solution? Or may be you just know how to configure SAML 2 for this case.
Thanks in advance,
