Implementing Devolved Constraints

1. Download the jdbc connector for Microsoft SQL Server

The oldish version of java on the server might cause a compatibility issue as the java version is 6 :
see https://docs.microsoft.com/en-us/sql/connect/jdbc/system-requirements-for-the-jdbc-driver
Requires a Java Runtime Environment (JRE) 7.0. Using JRE 6.0 or lower will throw an exception.
Looks like we need version 4 of the jdbc connector : https://docs.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server-support-matrix#java-and-jdbc-specification-support
But it looks like it's no longer available "We're sorry, this download is no longer available."

1. Install the connector in the "lib" folder in the Tomcat Shibboleth application
2. Modify the CLASSPATH variable to include the connector
3. Perform a re-install of Shibboleth using the install script
4. Edit the Shibboleth config files
