WSO2 single sign on with Identity Server - wso2

Question

I try to create a single sign on (SSO) using identity server for wso2. I follow this tutorial: https://docs.wso2.com/display/IS500/Enabling+SSO+for+WSO2+Servers In my case I want login in DAS with the Identity Server (IS). I installed DAS and IS, the IS by port 9443 using https and DAS by port 9445 with https. When I try to login in DAS the system redirect me to IS login form, this is correct, but when I write user and password the system emit this error (view image)
This is log error in wso2is (Using IS:5.1.0, DAS:3.0.0):

You need to upgrade the JCE so you can use 256 bit or more.
The solution for Java 8:
Download the Java Cryptography Extension (JCE) from http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
Copy the files inside jce_policy-8.zip to ${java.home}/jre/lib/security/ and any other java ubication.
Restart you machine.
