Hi Mike,

I have been successfully using Active Directory authentication feature on one of our clients site. But today we got a email from the clients saying:

"We have an issue that has cropped up post Active Directory migration to AD 2008 and Domain Controller name changes that occurred today.  If you notice the url is linking to Authentication Services/ActiveDirectory and is failing.  I am guessing this is using LDAP to authenticate instead of Windows and is pointed at a server name instead of an ip address as the ip addresses stayed the same but the name of the servers changed. "

I am not sure exactly what she mean and how to achieve it. Is it possible to do that? I need to retrieve Names and emailIDs from Active Directory. I need to fix it as soon as possible. I will really appreciate any help.

My settngs for AD connectivity are:

Enabled: True

Synchronize Role?: True

Provider: ADSIAuthenticationProvider

AuthenticationType: Delegation

Root Domain: dc=domainname,dc=com

Email Domain: @domainname.com

Rest of the fields are blank and with these settings the site was working perfectly fine untill clients made above mentioned changes.

Thank you very much in advance,

Divya

Thank you Mike.

Yes, I am running impersonation in web.config. This is how it looks like:

<!-- forms or Windows authentication -->

    <authentication mode="forms">

      <forms name=".DOTNETNUKE" protection="All" timeout="999" cookieless="UseCookies" />

    </authentication>

    <identity impersonate="true" userName="domainname\MyUsername" password="MyPassword"/>

Mike,

Client reported today that their problem is solved on its own. Maybe some restarts were needed on their part after the major updates. Thank you very much for your support. Atleast, I got some more information that AD 2008 should not be an issue for our DNN AD authentication functionality

Thank you once again for your support,

Divya
