Integrated Windows Authentication - Does not work on Virtual websites
|
|
|
| Hi,
Please, kindly let me know that there has been no answer
for my posting for a long time. I have another site
created in the webserver [Win2k and IIS 5.0]. A folder
within this site needs to be password protected and it
should use Windows Authentication. I have disabled Basic
Authentication and have only enabled Integrated Windows
Authentication. But, it does not authenticate and it goes
in straight to the website. Is this a security flaw in IIS
4.0 and IIS 5.0?
Please is there anyone with IIS expertise. Let me know
What could be wrong?

| a) Is anonymous authentication enabled? If so, disable it.
b) Are you using Internet Explorer? If so, it may be automatically logging
you in, if the site is in the local Intranet security zone. see:

| Ken,
Thanks for your response. The answers are as below.
1.Anonymous Authentication is not Enabled.
2.I am trying to test this site from the Intranet. But,
even trying it externally it does not work either in
Windows NT 4.0 IIS 4.0 or Win2K and IIS 5.0.
This site is not in the default website, but another site
has been created which is a virtual site in IIS.
This has not been working in IIS 4.0 nor in IIS 5.0.

| This is very doubtful.
Also remove rights of guests/IUser_Mashinename from this directory through
NTFS permisions.

| I've been testing IIS integrated securities to discover the best way to set up departmental web folders on our Intranet. My development/testing computer is Windows 2000 with IIS5. We have a Windows 2000 domain with Active Directory. My application se
rver is ColdFusion 5, but I will just address my IIS findings. When I set up Integrated Windows Authentication on a folder in IIS (both anonymous and basic turned off), IIS does pick up the user's domain id (this is authentication). When I create a
virtual directory to a folder that is physically on the web server, the domain authorization to this folder works (logged in users without permission to the folder are rejected). However, when I defined a virtual directory to a folder that is NOT on the
web server, IIS asks for a name and password to use when getting the folder. It appears to me that this named user (not the logged on user) is the one that determines whether authorization to the folder is accepted or rejected. In my testing, if th
e folder's physical location is NOT on the web server and the user named when setting up the virtual directory is authorized for the physical folder, then the logged on user is passed on into the web pages, even if he/she is not authorized for the folder.
In other words, NTLM authorization of the logged on user for folders only worked for me when the folder physically resided on the web server. I hopes this helps.

| The folder resides in the same webserver.
OK let me make it more clear
There is a Default Website created by IIS where most of
our contents are there.
I have another website say the name is LOCATION in the
same webserver. And under this there is a folder that
needs to be password protected. So, this is the one which
is not working.

| Hi thanks for your answer........well, there is no
IUSER_Machinename in this directory which has been given
permission.
I do not even given EVERYONE permission on this folder. I
have only one user who has permission for this folder
which when they access this site, it should pop up and
they should enter this userid and password to access it.

| John, I don't quite understand. Did you set up a separate website in IIS that shows in the manager in addition to your Default Web Site, or did you just create a new virtual directory in your Default Web Site? This 2nd method is the only one I'm famil
iar with. In this case the authorized user (set in the folder Securities property) should be passed on in without IIS requesting a name and password, and unauthorized users should be rejected. I do all my programming in ColdFusion and I can grab the
user's domain id function named CGI.AUTH_USER. Do you have a way to grab and display the user's domain id that is detected by IIS? I'm not at all an expert, I've just been testing these things for the last week.

| Hi John,
In IIS 4.0 and IIS 5.0, can you ensure that logging for the website in
question is W3C Extended, then choose to log all the properties for each
request (in particular the cs-user etc).
Then perform some requests for files in that directory, and post the
relevant lines from the logfile to the group? I'd like to see if IIS think
that the browser is sending some credentials.
If worst comes to worst, we can install Ethereal (www.ethereal.com) on your
client machines, and do a network capture of the traffic passing back and
forward between IIS and your browser, and then I can tell you what auth
mechanisms IIS is using, and what the browser is doing in response.
Cheers
Ken
