disabledAlgorithmsproperties at once. Use the new property in the disabledAlgorithms properties, precede the full property name with the keyword included.
- The Kerberos client can now take advantage of more dynamic environment configurations and do not necessarily need to know (in advance) how to reach the realm of a target principal, thanks to enhancements made to the Kerberos client with the support of principal name canonicalization and cross-realm referrals.
