Adapters
Virtual member manager uses adapters to adapt the entity types in the virtual member manager domain model to the various types of entities used by the repositories that are supported out-of-the-box.
Out-of-the-box virtual member manager supports adapters for:
- a file-based repository
- a virtual member manager database repository
- an LDAP repository
- a local operating system repository
- a custom repository
Additionally virtual member manager has adapters for a property extension repository and an entry mapping repository.
- File adapter
This adapter is for file-based repository used with the WAS.- LDAP
The virtual member manager LDAP adapter maps the virtual member manager entity types to the corresponding LDAP object classes.- Database adapter
Out-of-the-box, virtual member manager provides a default database profile repository (wimDB), that supports all common virtual member manager supported profile repository features.- Property extension repository adapter
Some LDAP repositories do not support certain type of properties and some LDAP repositories are read only. If virtual member manager is unable to write data to an LDAP repository, it can use a property extension repository to store the properties.- Entry mapping repository adapter
Use the entry mapping adapter to connect multiple repositories in an entry-level join.- Custom repository Adapter
A custom repository adapter enables the use of any custom repository used by virtual member manager.- User registry bridge
The user registry bridge is a read-only adapter that provides an interface between federated repositories and an underlying user registry implementation, which can be either a local operating system user registry or a custom user registry implementation.
