I spent hours trying to find a simple way to get user data our of AD from an LDAP query. Turns out you don't need to do a lot of crazy stuff, and looking at my code when I was done, it turned out to be a lot easier than it seemed when I started out. The only thing I need to pass in to my function was the name of the property ( see the list here ), and the username. In my case it was coming from some other logic I had to write to get the users of a group that was a member of a SharePoint site. Also the ldapPath I pass in to the DirectorySearcher constructor was simply "LDAP://mydomain.com" This returns the value of the property of the user that you specify as a string. Example: getValidADProps("mail", "Ima User") will return the AD email address for Ima User. In the function, I used a try/catch in the instance that the property you are trying to find isn't there, you will get a index out of range error. I will say that this is not the more lightweig...
