Out of the box adapters for federated repositories provide File, LDAP, and Database adapter for your use. These adapters implement the com.ibm.wsspi.wim.Repository software programming interface (SPI). Custom adapters for federated repositories need to implement the same SPI.
Refer to the Repository SPI implementation information in the related references for information about the custom adapters for federated repositories SPI.
Custom adapters for federated repositories must not depend on any WebSphere Application Server components, such as data sources and enterprise beans. These WebSphere Application Server components require that security is initialized and enabled prior to startup. If your implementation of the virtual member manager custom adapter needs to use data sources to connect to a database, you need to use Java database connectivity (JDBC) to make the connection during server startup. Then, at a later time, switch to using the data sources when the data source is available.
