within the database; encrypting them while they are stored adds another layer of
protection. This object class has one attribute, nsEncryptionAlgorithm , which
sets the encryption cipher used per attribute. Each encrypted attribute represents
a subentry under the above cn=config information tree nodes, as shown in
Figure 3-3.
Figure 3-3 Encrypted Attributes under the cn=config Node
For example, the database encryption file for the userPassword attribute under
o=UserRoot would appear in the Directory Server as follows:
To configure database encryption, see “Database Encryption,” in chapter 3,
“Configuring Directory Databases,” in the Red Hat Directory Server Administrator’s
Guide. For more information about indexes, see in chapter 10, “Managing
Indexes,” in the Red Hat Directory Server Administrator’s Guide.
nsEncryptionAlgorithm
nsEncryptionAlgorithm selects the cipher used by nsAttributeEncryption .
The algorithm can be set per encrypted attribute.
dn:cn=userPassword,cn=encrypted attributes,o=UserRoot,cn=ldbm
database,cn=plugins,cn=config
objectclass:top
