Can I open an database with an URL and send login-info?

I want to create an application i Excel. In Excel I will send an URL to a Domino-server to get information from the Domino-server to Excel.

My user are not users in the Domino directory, the can only login to Domino by http. I use an LDAP-directory to verfiy users.

My users have Office/Excel 2000

I know the “username” and I can get the password.

I want to open an URL like

http://server/database.nsf?login&user=myID&pwd=secret

Can I send userinfo or logininfo in the URL?
