Populating drop down list from AD

[Chris Geier]

string strLdap = "LDAP://OU=Sales,DC=Company,DC=com"
DirectoryEntry objOU = new DirectoryEntry(strLdap);
DirectorySearcher objUserSearcher = new DirectorySearcher(objOU);
SearchResultCollection objResults;
//Search for user objects
objUserSearcher.PropertiesToLoad.Add("cn");
objUserSearcher.Filter = "(objectClass=user)";
objResults = objUserSearcher.FindAll();
DropDownList1.Items.Add("New User");
//Loop through the search results adding each one to the combo box
foreach (SearchResult objResult in objResults)
DropDownList1.Items.Add(objResult.Properties["cn"][0]);

What am I doing wrong here...

This works for me:

string strLdap =
"LDAP://serverName/CN=Users,OU=Sales,DC=Company,DC=com";
DirectoryEntry objOU = new DirectoryEntry(strLdap, "userName",
"password");
DirectorySearcher objUserSearcher = new DirectorySearcher(objOU,
"(&(objectClass=user)(objCategory=person))");
SearchResultCollection objResults;
//Search for user objects
objUserSearcher.PropertiesToLoad.Add("cn");
objResults = objUserSearcher.FindAll();
DropDownList1.Items.Add("New User");
//Loop through the search results adding each one to the combo box
foreach (SearchResult objResult in objResults)
DropDownList1.Items.Add(objResult.Properties["cn"][0]);

Oops, to hasty in copying and pasting; replace this line

DirectorySearcher objUserSearcher = new DirectorySearcher(objOU,
"(&(objectClass=user)(objCategory=person))");

with
DirectorySearcher objUserSearcher = new DirectorySearcher(objOU,
"(objectClass=user)");

or simply use
DirectorySearcher objUserSearcher = new DirectorySearcher(objOU);
and add the Filter you were using in your own code snippet.

I can get this to work perfectly in a winform. But when I want to do it from
a webform it does not work. I am getting 2 error messages focused on the last
line of code

The best overloaded method match for
'system.web.ui.webcontrols.listitemcollection.Add( string)' has some invalid
arguements

and secondly

Arguement 1 cannot convert from object to string.

[John Bailo]

It expects an object, whose value is type string.

Example:

listBoxData.Add(New ListItem("apples"))
