I'm trying to use the object model of Sharepoint 2007 to make some changes over a list and read users and groups web settings...

For that I developed a Web Service (WCF) that is stored in the same web application as the sharepoint site in IIS.

Thats working.

I call inside the Web service


and thats user is not me, is "Sharepoint\System"


Other thing is that web I try to get all users using


that only contain "Sharepoint\System", not the others.


I give the full trust in the web.config and use the Ntlm authentication method.

The Solutions is:


(the name of the user of the application pool is the same as the loggin user)


Your web service is running as the SharePoint system account, taht's why you get that account as the current user.
