CN=David Hinkle EmpID=1234 Dept=ISSL CN=David Hinkle EmpID=1234 UID=DH9876 database 1 database 2 Figure 8-13 Central master directory 342 Lotus Security Handbook central master CN=David Hinkle EmpID=1234 Dept=ISSL Mail=dave@ibm.com UID=DH9876 database 3 As illustrated in Figure 8-13, the central master performs the function of aggregating all attributes and storing them in a “master record.” The arrows depicted show the data flow going from the source directories (databases 1, 2, and 3) to the central master. Note that the CN and EmpID attributes are being used as the correlation keys for data provided from databases 1 and 2. This is a typical scenario where the master directory aggregates feeds from all other subordinate/spoke directories. Although the diagram does not depict this, note that it is also possible for attributes stored in the central master that came from one subordinate to be pushed from the master to a different subordinate directory. Typically, a limited number of attributes are shared between the subordinate directories in this architecture. When updating attributes in the subordinate directories, it is extremely important to keep track of the authoritative source of each attribute. A central directory generally does not strictly enforce authoritative sources. As a result, care must be taken when allowing the same attribute (other than correlation keys) to be accepted from the subordinates. Metadirectories have the advantage of real-time merging of data in addition to directory synchronization, but with this capability comes risks associated with the performance of the service. Because the various source directories are accessed over network connections, the data retrieval via the connectors is only as fast and reliable as the underlying infrastructure. Central directories have the advantage of being able to provide the merged data immediately. However, the frequency of the synchronization with the spoke
(source) directories can limit the accuracy of the data provided. They also can require significant server and storage resources. An alternative approach is a combination of the two strategies. A combination approach, as shown in Figure 8-14 on page 344, uses a metadirectory to perform flexible data merging between the different source directories, and also uses a central repository directory as a nonvolatile store of the merged data to be used by applications requiring the directory service. In this hybrid approach, the central directory is a data receptor and generally does not allow direct updates, but is offered as more of a read-only LDAP service. The one area where the directory would need to permit direct updates would be for user passwords, since these cannot be synchronized (see “Password synchronization” on page 284 for more information regarding issues with passwords and synchronization). By having an LDAP directory that contains the merged data, the latency issues involved with virtual, dynamic data merging can be avoided. This approach is ideal for an organization that wants to migrate data and applications to use a common LDAP directory, while continuing to support applications that are dependent on proprietary or legacy directories.
