NAC SSL Certificates

Hello there,

I installed NAC and cutover to production env. without changing the perfigo root certificate. This is because i had no CA server.

Now i've got a win 2003 Standalone root CA Server configured. What is the impact on requesting certificate from this CA and install it on the NAC server and Manager?

regards,

Stanslaus.

Stanslaus,

No impact if you do it right. Details on adding a cert from 3rd party (in this case your own CA)

CAS: http://tinyurl.com/yju2jcy

CAM: http://tinyurl.com/yglhq3w

This is assuming 4.5

Clear your cookies in the browser and try again. I've seen that before and clearing cookies helps. If that still doesn't help let me know and I'll send you a PDF of the relevant portion

Hi Faisal,

I've cleared cookies but no success. I've tried 3 different browsers also(Int expl, firefox and Epiphany) but ending up with the same message.

Stanslaus,

Within the URL try changing the word partner to customer and try again.

If that still doesn't work, email me and I'll send you the relevant portion in PDF

Re: NAC SSL Certificates

Hi Faisal,

I managed to install certificates from my internal CA Server and remove the perfigo certificate. The problem is that users are still required to accept the certificate everytime they login.

Stanslaus.

Re: NAC SSL Certificates

Stanslaus,

Is the root certificate (from the CA which issued the CAS/CAM certs) installed on the clients? If not, can you please install that root cert on the clients and try again?

HTH,

Re: NAC SSL Certificates

Hello,

We have deployed a similar scenario and we solved this issue by installing an ID cert of every PC; the ID cert of course was issued by the same CA Authority used by the NAC Servers.

Hope it helps.

Re: NAC SSL Certificates

Hi Denis/Faisal,

I accessed the CA web from one of PCs giving the warning and found a place to install ceritficate chain ( written "To trust certificates issued from this certification authority, install this CA certificate chain."). I click install and it was successfully installed. The PC keeps on giving the warning. Is this the correct way of installing the root certificate on PC? If not please where can i find a guide on how to request the certificated from the CA?

Thanks.

Stanslaus.
