Outlook Web Access Authentication

I've recently setup an Exchange Server behind our comapny firewall and am presently configuring it to allow Outlook Web Access for users who wish to check their email from outside the company WAN. The port allowing access through the firewall is working correctly and brings up the login asp page for OWA, however a logon box appears asking for usename, password and domain. When you enter your information, the logon box reappears after a few seconds and prompts for a password again. If you enter your password a further time, the window then goes white with the address bar url address looking like it has authenticated you. The access to this service is via https and we use SSL/clear text authentication.

Attempting to access the same service over the LAN/WAN (ie not through a dialup connection) takes the user straight into their inbox. The url access for this is also done via https but to the servers internal IP.

What is puzzling me is why it's asking for a domain logon account to access email?

Anyone help?

When a user connects over the local LAN, they are authenticating to your domain by logging in. Then when they connect to OWA, they already have the credentials they need to access their mail.

When a user connects via the Internet they have not authenticated to the domain. OWA (and Exchange) requires a domain username, password (and mailbox alias if different than the username) to allow this unauthenticated connection access to the mailbox.

No, our login environment is Netware based with the NT server running purely as a PDC for a Winframe server. Over the LAN I can login as a user without domain authentication because the Netware UID and passwords are the same on both Netware and NT. Once that cached password is passed onto the OWA it authenticates them automatically to the NT server.

I tried a DUN connection from a friends machine last night and got through to the server on entering the domain id first time.

Went back and check my machine, bloody cookies! My jury is still out on cookies so I disable them by default. OWA seems to require them turned on to cookie the domain id on the local machine. All working now.

Dude, I'm going to give you the points anyway for a quick response to the question.
