Problem

Datameer doesn't work once Kerberos is installed.

The following error message appears:

	... 85 more

Cause

Some operating systems use AES-256 for Kerberos principal. If the correct JCE is missing, the client fails to authenticate to Kerberos.

Solution

Download the unlimited JCE package from the Java Oracle website and follow the README in the same package.
