oops sorry thought you asked for forms authentication

Hello seckel,

If I understand your question correctly, you need something like forms authentication where user enter their user name and password to login your intranet site. And currently the intranet site is using windows authentication. Am I right? please clarify.

this might help

The following MSDN Article describes exactly what you are trying to do:

Title: Active Directory Authentication from ASP .NET

I have a form that will get the user's name and password.  I then need to authenticate the user name and password against Active Directory (ADSI)...I know how to create the form, I need help with the ADSI logic portion...

The link is good, but in C#.  I need to know how to do this in vb.net.

ihenry,

You are a genius!  That was just what I needed.  Thanks.

nah...just glad I could help :0)

ok so how do you get the LDAP path?
Dim adPath as String = "LDAP://DC=..,DC=.." 'Path to your LDAP directory server

i have tried this one:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;326340

but i don't know what to use for Path to your LDAP directory server

Dim adPath as String = "LDAP://DC=..,DC=.." 'Path to your LDAP directory server

Check the following tutoria:

URL: http://www.codeproject.com/aspnet/adsi1.asp

You can define it as
LDAP://IP_ADDRESS
LDAP://DOMAIN_NAME

HTH, Nauman.

This was the format I needed:

LDAP://domain.ccc-xxxx.net
