ACS certificate renewal

aosandoval — Mon, 11 Mar 2019 00:22:36 GMT

Hi all,

It's time for me to renew the certificate on a ACS appliance running 4.2

For renewal, what is the process to follow?

I am using a Windows 2003 CA.

Thanks

Hi,

It depends on the CA server policy , some CA server wants to regenerate the CSR and others dont. You need to contact the CA administrator for this.

Howver here is the link that can help you get the cert for ACS :

Note : Look figure 3-39

Hi Waris,

The link seems to be broken...

By renewing the certificate, will all clients be affected?

or is only between the ACS and Windows?

Thanks

I have attached the equivalent PDF file for the link.

Assuming you are using certificate for PEAP the new certificate might come with new serial number and client may be asked to install the certificate.

Thanks

Hello Waris,

I would like to thank you for your feedback on this discussion.

I was able to renew the certificate in the ACS without a problem.

Hi,

Can you share with us how you renewed the certificate without having to install a new one ? I'm running into the same problem - I need to renew the certificate without having to install a new one on all the devices. I'm using ACS SE 4.2.

Thanks.
