User Management EngineLocate this document in the navigation structure

The user management engine (UME) provides a centralized user management for all Java applications and can be configured to work with user management data from multiple data sources. It is seamlessly integrated in the SAP NetWeaver Application Server for Java (SAP NetWeaver AS for Java) as its default user store and can be administrated using the administration tools of SAP NetWeaver AS for Java.


The UME adds business value by enabling you to leverage your existing system infrastructure by accessing user-related data on an existing LDAP directory, an SAP NetWeaver Application Server for ABAP system, a database of SAP NetWeaver AS for Java, or any combination of these. In addition it reduces administrative overhead by allowing you to perform centralized user administration.


The UME runs as a service in SAP NetWeaver AS for Java and is the default user store.


Multiple Data Sources

The UME can be configured to read and write user-related data from and to multiple data sources, such as Lightweight Directory Access Protocol (LDAP) directories, the system database of SAP NetWeaver AS for Java, and user management of SAP NetWeaver Application Server for ABAP.

The following figure illustrates the architecture of the UME.

In the figure, user data is stored in one or more data sources. Each type of data source has its own persistence adapter. The persistence manager consults the persistence adapters when creating, reading, writing, and searching user management data. The application programming interface (API) is a layer on top of the persistence manager.

In the persistence manager, you configure which data is written to or read from which data source, so that the applications using the API do not have to know any details about where user management data is stored.

User Administration

Identity management enables administrators to perform routine administration tasks such as creating or searching for users and groups, and assigning users and groups to roles. You can also configure the UME for e-mail notification. E-mails are automatically sent to users or administrators on specific events. For example, if an administrator locks a user account, the user receives an e-mail informing him or her of the change.

Security Settings

You can define a password policy including settings such as minimum and maximum length of passwords, number of failed logons before the system locks a user, and so on.

Self-Service Scenarios

UME provides self-service scenarios that allow users to register themselves as new users or to change their own data (address, password, and so on). It is also possible to set up an approval workflow, whereby administrators approve newly registered users.

Security Logging

The UME logs important security events, such as successful and failed user logons, and creation or modification of users, groups, and roles.

Import and Export of User Data

The UME enables you to import and export user data from and to external systems.

Virtual Groups

The UME enables you to define virtual groups based on the content of a user attribute.


Enables you to support delegated user administration.

Simple Search Configuration

You can configure what attributes the simple search targets.

SPML Support

The UME APIs support access using the Service Provisioning Markup Language (SPML).

SAP NetWeaver Identity Management Identity Center uses the SPML interface to access the UME.
