Can login domain be set to a default? Gery D. Dorazio 08-31-2005

When users access a secured web site I manage the normal Windows login
dialog appears requiring the username and password. The username text box
requires the domain\username to be entered. Windows Integrated
Authentication is being used as the authentication method.

The web site hardware for this system is a web server box, a DNS box with
Active Directory, and a database box. (This is a SharePoint installation.)
The internal domain for the three servers is different than the web site
domain defined for the internet. Correct me if I am wrong but I think this
is why the username text box requires the domain\username and not just the
username. Is this correct thinking?

If my thinking is correct so far (or if it's not and you can correct me)
then my fundamental question is how can I configure this setup to not
require the domain part of the login? I do not want to change the internal
domain of the three servers. Is there an alias capability where the internal
domain can be aliased to match the external web domain being requested?

Thanks for any suggestions.

Gary,

If by "external web domain" you are meaning the DNS name for the
site as known by the browsing public, then this has no impact on the
need for specifying a login domain.

They need to say domain\user because the IIS is on a member and
you are having them use domain accounts instead of machine local
accounts of the IIS box (and the login process needs a way to
distinguish). If you drop the Windows integrated and go to clear
text authentication then you can still use domain accounts and you
can specify a default login domain. Of course the clear text nature
of this is definitely not desirable. In standard as-it-ships IIS you
cannot specify a default domain for Windows integrated authentication
(since that is a challenge response discussion where IIS is not an
intimate intermediary able to "adjust" what is being exchanged).
I believe that you might actually want to look at the digest authentication
capability of IIS 6 or of the older MSCS membership services.

Thanks Roger for the insight.

Currently the site will use clear text as it is running entirely through
SSL...and some of the user base may not be using IE. So I will do as you
suggest and set the default login domain in clear text mode. (I assume that
is done with IIS Manager...)

It didn't occur to me that the server has to distinguish between the
machine and domain accounts...

Thanks,
Gery

Yes, the default is set in IIS mgr. To force use of clear text just
leave it as the one enabled login method. With clear text the IIS
server gets to be privy to the name and pwd, and so can alter.
