Can anybody tell me where the users of the sap back-end system store?Does portal share its data source with the sap back-end system?

Hi Lei,

The users Data is stored in USRXX TABLES following are some of the examples.

USR01 User master record (runtime data)

USR02 Logon data

USR03 User address data

USR04 User master authorizations

USR05 User Master Parameter ID

USR06 Additional Data per User

In portal you have seperate database for users.

The connectivity from SAP to portal through RFC.

From Portal to SAP its JCO's.

Hope this helps to an extent

Cheers

If the Portal is installed on a SAP system where the JAVA engine was installed as an "add-in" to an existing ABAP engine, then it is common (but not mandatory) for the user store to be accessed via UME, so that only one user store needs to be maintained. e.g. The user store in the ABAP engine will be accessed when needed by JAVA engine code, such as the Portal.

If however, the JAVA engine which the Portal is installed on is not configured to use UME, then it will have its own user store, which needs to be maintained using different user admin tools.

In either case, the SSO2 tickets issued by one system can be configured to be trusted by others, so it is possible to achieve SSO regardless of the user store used.

Hi,

In portal if the UME is configured with ABAP data store then the user details will be stored in the ABAP system. Otherwise the details will be stored in LDAP / DB.

To know more about on SSO in Portal please, refer the link below.
