Preconfigured Data Source
Combinations 
User Management Engine (UME) provides ‘template configurations’ that define a configuration for standard scenarios for dealing with user management data. These template configurations are XML files referred to as data source configuration files. When you choose a user management configuration during installation, the installation routine automatically chooses the correct data source configuration file. If you change the data sources manually after installation, you have to specify your required data source configuration file in the UME property ume.persistence.data_source_configuration.
In the following section, you can find an overview of the available data source configuration files. Under the section dealing with a particular data source, for example LDAP directory, you can find a description of all configuration files that use an LDAP directory as the main data source. There are three main data sources:
·
Database Only as Data
Source
·
LDAP Directory as Data
Source
·
SAP NetWeaver AS ABAP
User Management as Data Source

You can find
most of the configuration files using the Config Tool as described in
Editing UME
Configuration Files. For LDAP directories that have only recently been
certified, you can get the configuration files from the LDAP directory vendor
directly.
For restrictions to changing data source configurations after installation, see SAP Note 718383.
