I have a webservice based app that a company has purchased to use
internally.  They want the authentication to integrate with their Active
Directory.  Is there anyway that the client portion of the application
(which is a .NET WinForms app) can send some information about the logged in
user so that I could athenticate that user before accessing the database?
The database will not have individual user accounts  but will authenticate
using a table in the database.  The reason that I need this is so that the
company can push out the client app to it's users using Zenworks.  So, the
install must get the user data from the Active directory.  Therefore I need
to be able to use whatever information he can get from the AD and use it get
the same info from the AD from the webserver code.  One thing I was thinking
of using was the AD object ID (a guid) but I don't know how I would pass
that value to the DirectorySearcher's filter property and I don't know if
that's a property that the ZenWorks install can grab anyway.

So, to sum up the client app polls a webservice to get some data, I need to
be able to get some user information (gleaned from the AD) from the client
and authenticate the user, then connect to the database and retrieve teh
requested data.

Any ideas?

Thanks.
