How to get Active Directory connection string in C#.NET
First you will have to add a reference for System.DirectoryServices
You must run the application on a machine within the same domain to be able to connect to the Active Directory
using System.DirectoryServices;
private string GetActiveDirectoryConnectionString()
{
DirectoryEntry root = new DirectoryEntry("LDAP://RootDSE");
using (root)
{
string dnc = root.Properties["defaultNamingContext"][0].ToString();
string server = root.Properties["dnsHostName"][0].ToString();
string adsPath = String.Format("LDAP://{0}/{1}", server, dnc);
}
return adsPath;
}
