By default, changes to properties are made locally to a cache, and property values to be read are cached after the first read. When the UsePropertyCache property is true, access to the DirectoryEntry object's properties is faster. Setting this to false will cause the cache to be committed after each operation.
If the UsePropertyCache property is true and you want to commit cached changes, call the CommitChanges method. To update values in the cache after changes to the directory are made, call the RefreshCache method.
