  • Method and system for uniformly accessing multiple directory services
    Patent number: 6360230
    Abstract: The present invention provides a directory service system for accessing a plurality of directory services in a uniform manner. Each directory service manages information relating to objects of that directory service. The type of information that a directory service manages for an object is defined by the object class of the object. An object class defines the properties (i.e., information) that a directory service manages for objects of that object class. Each property has a property name and property type. A directory service has a property value for each property defined by the object class of each object. The directory service system comprises a schema browsing component, a name resolving component, a binding component, and an extending component. The schema browsing component controls the retrieving of the property name and property type of each property of each object class of each directory service.
