Windows, IIS and ASP gurus, please help!!!
I am at my wit's end here!!!
I have developed this wonderful application that is supposed to get the user's windows NT log in, compare that to the database and then go straight into the application.
It works well on the local PC, Windows 2000, SQL Server 2000, IIS 5.0. However, on a client-server environment, the application does not recognise the windows log in. Please do not tell me to do it in .NET, it HAS to be done in ASP.
Can anyone please come up with a solution that will work? Entering domain\username in the database is useless because the application will be used on three different domains!!!!
Here is the code that is supposed to do the magic, please pay particular attention the the lines that differentiate the servers:-
If Request.Servervariables("R
Response.Status = "401 Unauthorized"
'response.redirect("nologo
elseif request("REMOTE_USER") <> "" then
username = Request.Servervariables("R
'this part differentiates the three different servers
'IF request("SERVER_NAME") = "localhost" then
servername = left(username, 13) '-- removes domain OR netbios name alter to suite length of domain name.
'END
'if request("SERVER_NAME") = "MUNIN" then
'servername = left(username, 6)
'end
'if request("SERVER_NAME") = "CABWEB" then
'servername = left(username, 6)
'end if
userid = lcase(replace(username, servername, ""))
strSQL="SELECT * FROM Users where username = '" & userid & "'"
set rsUsers=Server.CreateObjec
rsUSers.open strSQL,objConn,3,3
If rsUsers.recordcount = 0 then
'response.write "There are no users matching the user name " & userid
response.redirect("nologon
Else
while not rsUsers.EOF
session("userid")=rsUSers(
session("user")= rsUSers("first_name") & " " & rsUSers("last_name")
session("team_id")=rsUsers
session("loggedin")= 1
session("style")="pms_medi
'enter path for uploaded files
if request("SERVER_NAME") = "localhost"
session("upload_directory"
'ELSEIF request("SERVER_NAME") = "MUNIN" then
'session("upload_directory
'ELSEIF request("SERVER_NAME") = "CABWEB" then
'session("upload_directory
'END IF
rsUsers. MoveNext
wend
response.redirect "projects/projects_home.as
end if
end if
Thanks.

Where are you stuck? How do you collect the data?
ASKER
I am stuck when the application is being accessed remotely via a client. Where IIS and SQL Server reside on the same box, the application is okay. Once IIS and SQL Server reside on 2 separate boxes, the application fails.
The data is pre-populated in the database.
The data is pre-populated in the database.
I do not understand what is failing and why. I will tell you how a 3 tier application is designed.
(1) UI - User interface is loaded from any client from practically any part of the world where your network is reachable. Apparently, this is okay here.
(2) Middle tier - Your web server (IIS). Problem is most liekly to be here. Do you have a DSN on this system that connects you to the SQL server? How do you construct the connection object objConn? Is that with a DSN? If so, you just need to see if you have localhost specified as the DB server name. If that is the case, specify the proper hostname of the SQL server. Depending on your network design you might have to use fully qualified domain name. Check with your Network Admin if yo are unsure about this.
(3) Back end - This should be okay. YOu may carry out a small test to verify this. YOu may try connecting from the client directly. If you are able to connect directly your SQL server is accessible from outside.
Let us know where do you now feel problem is.

First, a small note: For code claity, you may use the split function to get the domain and the userid out of the "domain\username" string.
domain = Split("domain\username", "\")(0)
userid = Split("domain\username", "\")(1)
Now, when SQL and IIS reside on 2 separate boxes, you may have an authentication problem. In your connection string, you can either:
- Include an SQL Server username and password, or,
- Make sure IIS anonymous access is disabled, change the connection string to allow to use Trusted Connection, and finally give the users access to the SQL database (e.g. From Enterprise Manager)
domain = Split("domain\username", "\")(0)
userid = Split("domain\username", "\")(1)

The connection string is something like this:-
set objConn=server.createobjec
Conn="Drive=r{SQL Server};SERVER={Actual server name};DSN={actual DSN name};DATASOURCE={Actual datasource}"
objConn.open Conn
Am I to understand that you want me to replace the Server name with localhost?
set objConn=server.createobjec
Conn="Drive=r{SQL Server};SERVER={Actual server name};DSN={actual DSN name};DATASOURCE={Actual datasource}"
objConn.open Conn
Am I to understand that you want me to replace the Server name with localhost?
Why not specify a UID and PWD in the connection string as well.
Did you perform connectivity test? Basically, the account with which IIS is being run you should be able to connect to SQL server and use the data as you need.

Where the application all sits on one box runs in my office on my local PC and I had no problem with connectivtity.
I now had to ftp all my files to a third party that handles networking for the client I am building the application for.that is where I encountered the problem.
Will try username and password and hope that it works.

RanjeetRain,
The adding of username and password seems to have helped.
That solves the problem, but let me be a bit sneaky while I am here.
I mentioned that SQL Server sits on a separate server to the application files. I also need to access two different databases. So, being the extremely clever person that I am (as is evident from all my questions, ahem), I wrote the following SQL string:-
SELECT (UnitID), (UnitDesc) FROM [CabWebDirectory]..[UNITS]
hoping that it will be enough. Was it? Nope!!!
I keep getting the error:-
Microsoft OLE DB Provider for ODBC Drivers error '80040e37'
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'CabWebDirectory..UNITS'.
Er...what???!!!

By the way, done the obvious, removed brackets.
ASKER
Oh, and connection string is:-
Conn="DRIVER={SQL Server};SERVER={Server 1 name};DSN=pms;DATABASE={PM
Conn2="DRIVER={SQL Server};SERVER={Server 2 name};DSN=dsn2;DATABASE={D
objConn.Open Conn,Conn2
Conn="DRIVER={SQL Server};SERVER={Server 1 name};DSN=pms;DATABASE={PM
Conn2="DRIVER={SQL Server};SERVER={Server 2 name};DSN=dsn2;DATABASE={D
objConn.Open Conn,Conn2

Thanks, it worked!!!
Glad you solved it!
This is not fair. I should be awarded at least some points. I answered your question before Ranjeet.

Can points be split?
Split? With respect to Ranjeet, but he just copied my answer. The fact that he answered your "Select" problem, which should've been asked in a separate question, doesn't give him the right to recieve points here.
Anyway, I leave it in your hands and to the PageEd.
