I am attempting to create new membership users in an Ektron CMS400.NET-based website by through calls to the User web service API from a remote site. One of the methods I intend to utilize, AddMembershipUser has a remark in the documentation indicating "A user with administrator privileges must be logged in to perform this operation.". I am already providing the necessary credentials via the AuthenticationHeaderValue object for calling the web service remotely. I have also made a call to the LogInUser method, to login one of my admin users, and this appears to be working. The point at which I am stuck is figuring out how to execute the call to AddMembershipUser as the admin user whom I just logged in. I have requests out to Ektron support, and have been searching both the forums and documentation, but have yet to find any answers.
Does anyone have examples of calling web service API methods as a programmatically logged in user, from a remote server?
