Re[2]: Prevent security bypass

Just out of curiosity, is there way to authenticate users to a
separate database other than the NT domain?

Here's one method of securing through IIS:

* Open up Internet Service Manager
* Find the directory or file(s) you wish to secure (they can been anything
from txt to pdf to html to whatever) in the tree on the left-hand side (if a
directory - right-hand side for individual file lock-down)
* Right-click the directory / file and select Properties
* If securing a file, select the File Security tab, if securing a directory,
select the Directory Security tab
* Select the Edit button in the top third of the property sheet
* Modify the security here
        I suggest turning off Anonymous access if you want to secure the
documents, and turning on Challenge/Response (NTLM) authentication if you're
users are all logged in on the network, or using Basic authentication if you
wish for a username/password dialog to prompt them.  Make sure all the
accounts you wish to access it have accounts in the specified domain.

HTH!

I am new to this mailing list and so hope this conforms to the guidelines as
I read them.

How do people address the issue of non-authenticated users requesting html
pages directly from a site without logging in?

FYI. This is an IIS server. Our asp pages check the user is logged in, but
with html pages we cannot.
My only idea so far is to convert all our html pages to asp. Is there
anything less drastic?
