What is UME ? UME is the central storage place for user and role information of all Java and ABAP applications that use UME. Persistence manager is responsible for writing the data to and reading the data from the correct data source. The application is unaware from which data source is the data being read or written to.
Various sources of data storage for UME are possible. Some are : SAP R/3 system, LDAP, Database etc.
It may happen that that the data source which is being used by UME is also required by some other system like SRM. In such a case a replication of the user information present at the persistence has to be made. This task is handled by the replication manager.
Two main packages in which almost all of the APIs of UME are covered is :
Com.sap.security.api and com.sap.security.api.acl
IUser, IGroup and Irole are present in com.sap.security.api. Also UMFactory and IUserAccount are present in this package.
IAcl and IAclManager are present in the com.sap.security.api.acl.
User Management factory
Applications can access all the functionality of UME through com.sap.security.api.UMFactory
Various other factories can be obtained from the UMFactory.
UME Objects are identified by Unique IDs. IUserFActory can be used to create, delete, search users. Also you can perform mass commit/rollback on a set of users The Iuser Object contains all the information about a user. Name, UniqueID, LDAP attributes, display name etc.
If you want to Modify a User Information, Use the IUserMaint Object. By using the Iuser, you can obtain information about the logged in user. Also you can obtain information about another User. You can obtain information about other User if you know UniueID of the user.
