SSO from Non-SAP(Java application) to SAP ECC Webgui

[former_member438762]

I get a requirement from customer as following:

1. He has a portal(Not SAP EP), a java base application.

2. he wants to access the SAP transaction by WebGui (application server is ABAP) through his portal, he doesn't want to enter user id and password during accessing SAP transaction through webgui.

3. he doesn't want to use the SSO based on client certification(X.509) or Kerberos Authentication

I have read a lot blogs, did not find any solution relevant for this kind of requirement? Any expert have experience on this ?

Based on your description, it looks like the easiest solution would be to implement SAML Single Sign-On.

How is this portal being accessed today? Do they have any SSO solution already that you could extend? Do they use any Identity Provider in their landscape?
