Check network configuration

Another approach to protecting attributes is encrypting them. Check network configuration Server has the capability to encrypt all instances of specified attributes. This means that for every object containing such attributes, the data in that attribute is encrypted using a symmetric key known to the directory server. Various encryption methods can be configured, and different attributes can be encrypted using different ciphers. Encryption and decryption are handled by the directory server itself, so access to attributes is not controlled by this method. However, data would be protected from unauthorized access if the directory data was stolen or otherwise compromised.

Metadirectories. Analyzing the origin of the word "metadirectory," we see the Greek phrase "meta-" which means "after," or "beyond." In modern English, this term often describes abstraction. Thus, a metadirectory is an abstraction of an actual directory. In this sense, it acts as a directory in some instances, by providing user interaction via LDAP, but does not act as a directory in other instances, because it is not the actual authoritative source of directory information. A metadirectory is used to abstract data from other directories into a single source, which can be used for two purposes
