摘要:
A new schema implementation enables reversible changes to be made to definitions in a schema. The definitions of attributes and classes are in the form of schema objects. Each schema object has an internal ID in addition to its unique name and object ID (DID), and a deactivation flag for indicating whether the schema object has been deactivated. To modify an attribute or class, the corresponding schema object is deactivated by setting its deactivation flag to “TRUE,” and a new schema object is created to contain the changes. The new schema object has the same unique name and DID as the old schema object but is given a different internal ID. When a client wants to access instances of the schema object by its unique name or DID, a translation is made to provide the internal ID of the new schema object such that instances of the new schema object are located instead of the old schema object. The changes to the schema can be reversed by reactivating the first schema object and deactivating the second schema object.
摘要:
A system and method for managing the creation of objects in a distributed directory service system assigns quotas to entities (such as users, computers, groups) to limit the number of objects each entity is allowed to create and own. For purposes of enforcing the quotas, tombstones generated for deleted objects are taken into account in the calculation of a weighted total number of objects owned by an entity, with each tombstone counted as a configurable fraction of a regular object. When an entity requests a directory operation that will increase the number of objects owned by that entity, the number of system objects owned by that entity is added to the number of tombstones multiplied by the fractional tombstone factor to generate the weighted total, which is compared to the quota of that entity to determine when the requested operation should be performed.
摘要:
A network computer maintains a directory of objects having multi-valued attributes. The attributes are comprised of individual linked values having conflict-resolution data that indicates a change to an object at an attribute-value level. A second network computer stores a replica of the directory in which a replica of the objects is maintained. The computers replicate the objects in the directories and update the individual linked values of the attributes. Replication conflicts are identified and resolved with the conflict-resolution data at the attribute-value level of the objects.
