Trying to use this code to connect the AD <pre class="prettyprint"><code>PrincipalContext context = new PrincipalContext(ContextType.Domain, domain) </code></pre> but i got the error saying: <blockquote> The LDAP server is unavailable. </blockquote> Any idea?

The questions is: do you specify our domain as <ul> <li>"mydomain.com" (DNS format)</li> <li>or as "dc=mydomain,dc=com" (AD-style format)</li> </ul> To my surprise, the Domain name must be in DNS format (e.g. "mydomain.com") in order for this to work (and NOT in the usual AD-style format of "dc=mydomain,dc=com").

The questions is: do you specify our domain as

"mydomain.com" (DNS format)
or as "dc=mydomain,dc=com" (AD-style format)

To my surprise, the Domain name must be in DNS format (e.g. "mydomain.com") in order for this to work (and NOT in the usual AD-style format of "dc=mydomain,dc=com").
