I have the following scenario with a customer. He has a network with an Active directory on a local server and a number of client computers. I am building a business solution that is to be hosted at an external ISP. I would like to do the following is possible:
The user is logged in against the local AD. The web site can access the AD via LDAP. How can I check the visiting users Windows user name from the web site and grant appropriate privileges automatically - without the user having to log in to the site?
If this can't be done - how would you suggest I do this in a way that is convenient for the user.
