Getting users from a specifc AD group

[egholm]

I want to get a list of users from a specific AD group. I use this
code:

****************************************************************************************
SearchResult result;
DirectorySearcher search = new DirectorySearcher();
search.Filter = String.Format("(cn={0})", groupName);
search.PropertiesToLoad.Add("member");
result = search.FindOne();

ArrayList userNames = new ArrayList();
if (result != null)
{
for (int counter = 0; counter <
result.Properties["member"].Count; counter++)
{
string user = (string)result.Properties["member"][counter];
userNames.Add(user);
}
}

****************************************************************************************


When the code is finished user string = "CN=Egholm Jacob (DFDS
A/S),OU=Development,OU=IT,OU=DFDS AS,DC=dk,DC=dfds,DC=root"

But what I want to do is getting information like givenName,
displayName etc. from the user.
What shall I do?

You should load the givenName and displayName property from the AD.

string[] props = {"givenName ", "displayName", ".."};
search.PropertiesToLoad.AddRange(props);
....

Thanks for your reply. I have change my code to this:

***************************************************************************­*************

SearchResult result;
DirectorySearcher search = new DirectorySearcher();
search.Filter = String.Format("(cn={0})", groupName);
search.PropertiesToLoad.Add("member");
search.PropertiesToLoad.Add("displayName");
result = search.FindOne();


ArrayList userNames = new ArrayList();
if (result != null)
{
for (int counter = 0; counter <
result.Properties["member"].Count; counter++)
{
string user = (string)result.Properties["member"][counter];

string test =
(string)result.Properties["displayName"][counter];
userNames.Add(user);
}
}
***************************************************************************­*************


The string variable test returns the name of the group and not the name
of the user in the group.

The string variable test returns the name of the group and not the name
of the user in the group.

If your cn denotes a "username", you should apply the following filter.

src.Filter = "(objectCategory=user)";

also, you should not use a for loop to iterate, use foreach instead.

Hello Willy

I have change my code (look below), but it still dosen't work.

*****************************************************************************************
DirectoryEntry searchRoot = new DirectoryEntry(@"LDAP://dfds.root");
DirectorySearcher search = new DirectorySearcher(searchRoot);
search.Filter = "(&(cn=Group CFS Handlers)(objectCategory=user))";
search.PropertiesToLoad.Add("samaccountname");

foreach (SearchResult res in search.FindAll())
{
string dummy = res.Properties["samaccountname"].ToString();
}
*****************************************************************************************

I want to list all the users in the group "Group CFS Handlers", but
search.FindAll() returns 0 results. I just checked the AD and the group
"Group CFS Handlers" contain one user.
I you have any idea what I do wrong, please let my know. I believe it
has something to do with my filter, but I don't know what.
