Hi, Trying to Kerberize my cluster, I encoutered some troubles. When I start to configure security with Ambari wizard, it seems the Ambari server cannot connect to the KDC, while it is on the same network. Therefore I took a closer look to the corresponding logs, and the main issue seems to be related to the Algorithm AES256, as the main error return "Algorithm AES256 not enabled". As I was a little surprised, I tried to reproduce the bug using a personal minimalistic implementation using the same library that is used by Ambari (org.apache.directory.kerberos.client), but I still get the error "Algorithm AES256 not enable" .
Searching on Google, I saw that this problem could be related to the installation of JCE, so I re-installed it with the proper parameters from Oracle website ( http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html ), but it did not change a thing. Does someone know where this might come from, or how to avoid this issue ?
