Hello

From a remote Win2k8 R2 server to a Win2k8 R2 server

I am using Get-ADUser just fine to my AD service using un-encriptedport 389 (credential settings are fine)

When I try to use port 636 and the parameter "-AuthType Basic" I get an error:

.......chain building failed.  The certificate that was used has a trust chain that cannot be verified.  Replace the certificate or change the "certificateValidationMode"..........

This is a self-signed certificate generated on the AD serverusing "Role: Active Directory Certificate Services" and works fine for other applicatons like - "Apache LDAP Directory browser"(trust ignored), "Softterra(trust ignored)" and even a Cisco "Call Manager Appliance (.cer installed)"  Regarding the Certificate - The "Issued to:,  Issued by:,  FQDN installed on DNS, AND is used in the Get-ADUser call.  (Get-ADUser -AuthType basic -server fqdn.dom.com:636 ........)   I have installed the cert into the Root CA, The intermediate CA, both on the Client Machine.  Used click on file and install,  Used MMC Certificates snap-in -> local computer.  I can see it in the "Trusted Root Certification Authorities" folder.

Powersehll 3.0 -> (Just upgraded since I first tried PS 2.0 as well)

How do I use "Get-ADUser" and specifiy ignore the Root Trust? (i.e. certificateValidationMode = none)

Thank you.
