IWP and external authentication

Hi everyone,

I've recently upgraded my system to version 7, running on server advanced patched to 7.0v3 and IIS6.0. Everything is running on the one box.

I had read that IWP cannot work with external authentication, but apparently it can, because authentication seems to work fine. I have set up a local group on the server itself with domain accounts of certain people who are allowed write access. All users in the company are in the the Domain Users group, which I have have set to give read access.

When I was playing around setting all this up, I could swear that if I was already logged onto the domain, Internet Explorer would go straight into the IWP page for the database (not concerned with the homepage), no authentication required. If not logged onto the domain, it asked for the password. That is definitely how it works via the filemaker client.

Something seems to have changed though because the web browser always asks for the password now, no matter what I'm logged in to. Is there any way I can get back the transparent logon behaviour, any settings I've inadvertently changed?

Or am I deluded, and it never, ever worked that way??

Thanks!

Sean.
