different ways to do User Mapping

[Former Member]

Hello all,

Could some one tell me about the ways in which we could map the user id to SAP r3 id. We already have a reference system which will do the user mapping.

Another way is to have the LDAP save the Mapped user id along with the authentication data.

Wanted to know if there are any other ways to do such a user mapping.

Thanks ,

Hello,

I already know what is UserMapping and the way it functions..

I want to know if there are any other ways to do user mapping other than use of Reference systems or Doing the mapping in LDAP itself.

Thanks

Hi,

User mapping is used for Single Sign-On (SSO) to back-end systems. User mapping maps a portal user ID to the user ID of the back-end system.

Systems are represented by their default alias in various interfaces, such as the User Mapping dialog that displays during personalization. To make a system available for user mapping, you must:

● In the System Aliases Editor, define a default alias for each system that you create. For information about creating system aliases and default system aliases,

● In the System Property Editor, set the User Mapping Type property to either:

--> User: Only the end user can set user mapping

--> Admin: Only the administrator can set user mapping

-->Admin/User: Both the end user and the administrator can set user mapping

User mapping supports the following authentication methods:

● SSO using user ID and password

This method always requires user mapping. The portal ID is mapped to the user ID and password of the back-end system.

● SSO using logon tickets to ABAP-based systems

This method only requires user mapping if users have different user IDs in the SAP NetWeaver Portal and ABAP-based systems. Passwords are not mapped.

To access more than one ABAP back-end system, you can define a reference system. As long as all the ABAP back-end systems use the same user ID, the user can access all the systems by mapping their portal user ID to the user ID on the reference system.
