Unable to authenticate admin user - Illegal key size

This means that the user is using a Java encryption level that does not match the license file being used.  This can happen if a different version of Java is being used other than what is shipped with webNetwork.  If this is the case then you have to download and install the Java high encryption files : http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

If the Java used is the one that ships with webNetwork then possibly a bad license file is being used and may need to be re generated with the appropriate parameters.
