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

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
