Very nice article. Here are my 2 cents.

Kerberos strong authentication relies on encryption. Different strengths of encryption can be used with the Kerberos tickets. Enabling Java to process the 256-bit AES TGT requires the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.The Unlimited Strength Jurisdiction Policy Files are required by the SAS Private Java Runtime
Environment. This environment is used by SAS Foundation for issuing a LIBNAME statement to the secure Hadoop environment.
