windows authentication: how to catch the case a user entered a wrongpassword

[Dan]

hi ng,

i have a problem with windows authentificatio n.

i want to forward every user who
1. is not authorized
2. or could not be authenticated
to a login page

-------------------
The scenario is an intranet application that can be used by some defined
active directory users.

web.config is like:
<system.web>
....
<authenticati on mode="Windows" />
<authorizatio n>
<deny users="*" />
</authorization>
</system.web>

<location path="private">
<system.web>
<authorizatio n>
<allow users="x,y,z" />
</authorization>
</system.web>
</location>

<location path="Public">
<system.web>
<authorizatio n>
<allow users="*" />
</authorization>
</system.web>
</location>

global.asax looks like:
protected void Application_End Request(Object sender, EventArgs e)
{ if((User.Identi ty.IsAuthentica ted)&&(Response .StatusCode ==
401))
{
Response.Redire ct("~/Public/Login.aspx");
}
}

----------------------
it is working when one of the x,y,z users enters the application with
the correct password or a domain user who is not x,y or z tries to enter
the application (with the correct password).
but it is not working when a user is not in active directory or a active
directory user enters a wrong password because in this cases, the user
could not be authenticated.
but i cannot redirect every not authenticated user, because before the
windows authentication form has been submitted, every request is not
authenticated, right?

i am getting a bit desparate, since i already have posted my problem,
with no replies.
maybe i am now able to describe the problem more clear.

thank you very much in advance for any help or suggestions

This is a little different for the windows authentication. You must set up
the<customError s> element in the web.config file to catch this unauthorized
message: See link below

http://msdn.microsoft.com/library/de...orssection.asp

The example showed an internal server error 500. So, you will have to add
your own element to catch for Error 403 (i think) for Forbidden. You can
look that one up

thanks for your help, but i have already tested <customErrors > in
web.config.
doesn't work.
maybe because the http response code is not like an error code?
