Using Kerberos Encryption Types

Encryption types identify which cryptographic algorithms and mode to use when cryptographic operations are performed. The aes, des3-cbc-sha1 and rc4-hmac encryption types enable the creation of keys that can be used for higher strength cryptographic operations. These higher strength operations enhance the overall security of the Kerberos service.

When a client requests a ticket from the KDC, the KDC must use keys whose encryption type is compatible with both the client and the server. While the Kerberos protocol allows the client to request that the KDC use particular encryption types for the client's part of the ticket reply, the protocol does not allow the server to specify encryption types to the KDC.

Note - If you have a master KDC installed that is not running the Solaris 10 release, the slave KDCs must be upgraded to the Solaris 10 release before you upgrade the master KDC. A Solaris 10 master KDC will use the new encryption types, which an older slave will not be able to handle.

The following lists some of the issues that must be considered before you change the encryption types.
