Hello All,

I have a webservice application (ASP.NET 2.0) and a .NET client executable 
which consumes the web services. The current model has username / password 
collected by the client application and passed to the webservice. What I am 
required to do is to make this application use active directory to 
authenticate the users and possibly implement a single sign on.

I can easily extend the existing model where I collect the username / 
password pass it to the server construct a NetworkCredentials object on the 
server and authenticate it against the active directory, what I've been 
asked to do is as follows :

Collect the current user's credentials 
(CredentialCache.DefaultNetworkCredentials) from the machine where the 
client executable is running, and (somehow) pass this credentials object to 
the server and on the server authenticate this object against the active 
directory. My questions are 1) Whether this is possible and 2) If this is 
possible, is this the correct approach? I have found lots of articles which 
suggest using integrated windows authentication on IIS, however I am being 
forced to not use it.

Can anyone please help me? guide me to any 'howto' article or something like 
that.

TIA,

SP
