LDAP SearchResult does not contain user properties

Question

I'm using DirectorySearcher.FindOne() method.

I have specified Mobile number in my Active Directory user properties. My search filter looks like this

(&(ObjectClass=User)(mobile=+11111111111))

With this filter I'm able to get appropriate user.

I've also specified Fax number in my AD user properties, but SearchResult does not contain Fax property. In fact SearchResult contain only one property, but I'm expecting all of user properties returned, including fax number.

Should I modify my query to get fax number returned? Maybe changes to my AD user or LDAP server required?

When using DirectorySearcher, you can define what properties will be included in SearchResult by using the PropertiesToLoad collection. If you don't specify anything, you only get the distinguished LDAP name

So try something like this:

DirectoryEntry root = new DirectoryEntry("LDAP://-your-base-LDAP-path-here-");

DirectorySearcher searcher = new DirectorySearcher(root);
searcher.Filter = "(&(ObjectClass=User)(mobile=+11111111111))";

// DEFINE what properties you need !
searcher.PropertiesToLoad.Add("Mobile");
searcher.PropertiesToLoad.Add("Fax");

SearchResult result = searcher.FindOne();

if (result != null)
{
   if (result.Properties["Fax"] != null)
   {
      string fax = result.Properties["Fax"][0].ToString();
   }

   if (result.Properties["Mobile"] != null)
   {
      string mobile = result.Properties["Mobile"][0].ToString();
   }
}
