LDAP Connection Using TLS on Firewall

I'm still stuck on this issue of trying to get our Sonicwall NSA 2400 firewall to successfully connect to our domain controller using LDAP and TLS. I've gotten the LDAP connection working, but the connection fails when try to connect when using TLS.

I've installed CA on the domain controller, but not sure what the next step would be, as it appears the firewall wants a certificate of some sort from our DC.

Thanks in advance,
Tim

Try this and make sure your security certificates are valid...

You will probably need to go to your CA server (https://<servername>/certsrv) if you are using Microsoft, and select "Download a CA certificate, certificate chain, or CRL" then select "Download CA certificate chain." You should be prompted to save the *.p7b file, you can just save it on your desktop.  

Now you need to log into your SonicWALL and go to "System->Certificates" then scroll to the bottom and select "Import."  Select the *.p7b file you just saved and import it.  You should now have your CA certificate installed in your SonicWALL so when it tries to establish secure connection, it will have the appropriate certificate.

I hope this helps.
