We have a requirement to configure SAML for SSO (Single-Sign-On) to SAP Enterprise Portal from an external system. Hence the portal would be the target system and the external system would be the source system. Assuming that the User IDs in both the systems are same, will SSO(SAML) work if the password expires in the target system.
Secondly, though the steps for configuring SAML is given in help.sap.com, certain things are not clear. In the section "Configuring the SAML Parameters", one of the steps talk about setting "SourceID" which is given as (20-byte sequence provided by the source site. Use the prefix Hex: or B64: to specify the format of the source ID as follows). How is this obtained?
Any pointers from someone who has experience configuring SAML would be greatly appreciated.
