Multiple User authentications to a web service?

Hi,

I have a Web Service installed on IIS6 (Windows 2003 SBS) with Directory
security set only to "Integrated Windows authentication" to avoid from
someone to use the Web Service.

I have set a Windows User with the necessary permission to use the Web
Service so it will be used from my Windows Forms application.

My question is there some kind of limit that the same Windows User will
authenticate the web service at the same time and from differences computers
as all the users of my application will use the same Windows User from my
application to use the Web Service?

Thanks in advanced,
Asaf

Hi Asaf,

Welcome to the webservice newsgroup.

As for windows authentication, generally each client request to server will
establish an logon session on the server-side, and even the users from
different machines use the same global account, they will be associated
separate logon sessions on the server. So I don't think their windows
idenitity on server will be shared or mixed. However, from the webservcie's
viewpoint, those client user using the same account will have the same
windows idenitity info, so the service still have no sense of the
difference between the client users unless we define additional
data/property to distinguish them. Also, each webservice method call is a
simple request to the server application over http, this makes it
stateless...

Thanks for your response Asaf,

So far I haven't found any definite limitation on such concurrent logon
session count. Anyway, this is purely depend on the underlying windows
platform's security implementation. Mostly it depend on our computer's
performance condition.
