Query will connect and perform a search on an LDAP server.

Query performs a search with the specified attributes in the Attributes action parameter and returns the results in a System.Data.DataTable variable. A common practice is to pass this variable into a CustomCode block for parsing the data within it. The following code shows how one would retrieve the an attribute of name cn from every found entry in the DataTable returned by a successful query in a CustomCode block:

public static string Execute(DataTable resultsFromQuery, ArrayList allCns)
{
    if(resultsFromQuery != null)
    {
        foreach(DataRow row in resultsFromQuery.Rows)
        {
            string cn = row["cn"] as string;

            if(cn == null || cn == String.Empty)
            {
                // this would presumably be an unexpected error that should be dealt with specific to the application
            }
            else
            {
                allCns.Add(cn);
            }
        }
    }

    return "success";
}

The branch condition returned provides useful information in determining the cause of failure:
