Enhancement #39 - I have now limited the search for groups to a
specified OU. This is now preventing all other system generated groups
not to be shown in the list of groups. Now this is also making this page
load up much, much faster as there is not that much information to look
up in the domain. I added the top level OU that contains all the groups
that we are interested in in the web.config file though this should be
stored in the database instead ... but this will come about later on in
the development of this application.
