RE: [ActiveDir] Secure LDAP queries from the outside

[Bernier, Brandon \(.\)]

Are you publishing a CRL? If so then it must use the path to the CRL that's specified in the certificate or it bombs out (latency to the hosting CRL server will kill it too..forgot the exact value). Why do you need CRL checking on your DC's? Doesn't that make you question who is on your DC's that would make you revoke a cert among other things? I would modify the template (if your using a Enterprise CA) and reissue the certs without a CRL and make sure the clients have the public key to your Root CA in their trusted root store. Something to ponder.   -Brandon  From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thommes, Michael M.
