Leighton, Try using ldapsearch in verbose mode (and debug mode) to get more info from AD.
ldapsearch -v -h <AD Server> -D "cn=<account to bind> dc=ad, dc=hud, dc=ac, dc=uk" -w <password> -x -b "dc=ad, dc=hud, dc=ac, dc=uk" "(sAMAccountName=mytestusername)" >From a Windows machine, you can also use tools from joeware.com, try adfind (http://www.joeware.net/freetools/tools/adfind/index.htm). Once you are able to successfully query AD from a Windows machine and/or ldapsearch, update your FR configuration and try again.
