c# - Login Authentication using Active Directory in the Intranet...Possible? -

i creating project deployed in our company's intranet. using code authenticate users login:

entry.username = strusername; entry.password = strpassword;  directorysearcher searcher = new directorysearcher(entry); searcher.filter = "(objectclass=user)"; try {     searcher.findone();     return true; } 

it working on localhost, when deployed intranet, can't log in.

now question is, can access directory on intranet? or there better way achieve this?
