Kerberos Authentication Encryption Setting
You can specify encrypted transmission between the machine and the key distribution center (KDC)
server when Kerberos authentication is enabled.
Using Kerberos authentication with Windows or LDAP authentication, LDAP search, etc., ensures safe
communication.
The supported encryption algorithm differs depending on the type of KDC server. Select the algorithm
that suits your environment.
