I am able to display Win Authentication Pop up by using
Authentication mode="Windows" and in Authrization tag,
deny user="?" and setting Win Integrated authentication in
IIS.

But I am not able to take user's info from Win
Authenication Pop-up Windows..as I used server variable

Dim domainAndUserna me As [String] = domain & "\" &
username

Private path As String
= "LDAP://AD/DC=AD,DC=SOLVER SA,DC=COM"
Dim entry As New DirectoryEntry( path,
domainAndUserna me, pwd)

Try
'Bind to the native AdsObject to force
authentication.
Dim obj As Object = entry.NativeObj ect

Dim search As New DirectorySearch er(entry)

search.Filter = "(SAMAccountNam e=" & username
& ")"
search.Properti esToLoad.Add("c n")
Dim result As SearchResult = search.FindOne( )

'Update the new path to the user in the

You cannot obtain the password from the login dialog when using integrated Windows based
authentication.

If you want to capture the user ID and password you will have to use Forms based authentication:

Thanks Paul for your cooperation,

But My requirment is to use Windows Authentication and
make a search in Active directory and get user's
information. For that I think I don't need user's
Password. Only with UserId I should be able to make a
search in Active Directory. Even I am able to do this when
my Web Application is on Active Directory's IIS. But I
have to make a search in such a senario that both Active
Directory and IIS are located on different phisical
machine. In this senario when I search using only Path and
user name...It raises an exception called
System.Runtime. InteropServices .COMException

I have search in msdn but did not get solution....

Please help me in this senario...

Thanks in adavance..
Hriday.

If your web server is in the AD domain you should be able to query AD.

What is the line of code that is causing the error?

If your web server is in the AD domain you should be able to query AD.
What is the line of code that is causing the error?

Hi Paul,

My web server in the AD domain only, but I am not able to
search user's info by the following code if I pass only
path as parameter to DirectoyEntry class..The same code is
working if I pass all the three parameter as path,userId
and password. but I can't get password from Windows
authenticatoin Popup box.....

I think I should be able to search in AD by only having
complete LDAP path and Username. I copy the complete code
here...I get error on following line
Dim obj As Object = entry.NativeObj ect

Thanks a lot for your cooparation..

COMPLETE CODE IS LIKE THIS...

Private path As String
= "LDAP://AD/DC=AD,DC=MyComp ,DC=COM"
Private filterAttribute As String
Public fullname As String
Public groupName As String
Public email As String

Public Sub GetUserDetails( ByVal domain As String, ByVal

Dim domainAndUserna me As [String] = domain & "\" &

Dim entry As New DirectoryEntry( path) ',

Is this the root path of your domain? It doesn't look right to me. What is returned as the root when
you execute the following code?

Dim RootDSE As New DirectoryServic es.DirectoryEnt ry("LDAP://RootDSE")
MsgBox(RootDSE. Properties("Def aultNamingConte xt").Value)

Hi paul, thank you for your help..

When I execute the above code to get root path of AD, I
get error that The
specified domain either does not exist or could not be
contacted.

But the same code gives my root path of AD as
DC=AD,DC=MyComp ,DC=Com when I excute it from a Windows
Applicatoin. Why is it so...?

same code gives right result from Windows App, but gives
above error from my Web Application...i s this because of
there is some problem of my IIS ? otherwise what is
different in accessing AD through Windows App and Web App..

How can I get and set my IIS root path to my Active
directory?

Please write me back...

Thanking you..

Hriday.
