Virtual Member Manager integration
IBM WebSphere Application Server includes the Virtual Member Manager (VMM), which IBM WebSphere Portal uses to access user and group information. VMM provides an interface that enables communication between WebSphere Portal and any repository, whether federated repositories, a stand-alone repository, or our own custom user registry.
The Virtual Member Manager (VMM) is an abstract component within the WAS infrastructure.
WebSphere Portal uses the Portal User Management Architecture (PUMA) System Programming Interface (SPI) to retrieve and set attributes on user objects. PUMA passes these requests to VMM, which then passes the requests on to a corresponding registry adapton that connects VMM to the repository.
The preceding diagram includes the following components:
- Federated Repositories
-
An out-of-box implementation of the UserRegistry interface that supports multiple repositories. To communicate with the federated repositories, both WAS and WebSphere Portal dispatch all operations to VMM.
- Standalone LDAP
-
An out-of-box implementation of the UserRegistry interface where a single LDAP directory is the repository. WAS communicates directly with the stand-alone LDAP. WebSphere Portal communicates with the stand-alone LDAP through VMM.
- VMM SPI
-
VMM offers a SPI, wim.Repositorythat enables communication with repositories. WAS uses this SPI to connect to federated repositories. WebSphere Portal uses this SPI to connect to all repositories, whether federated or stand-alone.
- User Registry Adaptor
-
An implementation of the VMM SP that enables VMM to connect to a specific repository, whether an LDAP directory, database, files, or other repository. Registry adaptors enable communication between WebSphere Portal and any repository.
Create a user registry adaptor if you plan to use a custom user registry or repository that WebSphere Portal does not support out-of-box. To create a user registry adaptor, implement the wim.Repository interface. Refer to the following topics in the WAS Information Center for information and instructions:
