Alright, I’ve gotten a lot of questions from people who aren’t familiar writing code on how to actually implement my active directory search web service I posted a long time ago. So here is a fully working sample. This is a self-contained ASP.NET 2.0 page that will search through the current domain it belongs too and return user’s FullName and Phone number as defined in there Active Directory profile. Only change that needs to be made is change:
protected void ldapsearch() {
string adPath = "LDAP://DOMAIN.COM"; //replace with your domain name, to restrict the search to a single OU tree use full LDAP notation ie: "LDAP://ou=Sales,dc=MyDomain,dc=com"
Continue on to see the full code, just copy and paste it into an ASPX file and throw it up on your iis server with ASP.NET 2.0 turned on.
