This value can be customized.

Login to CPG ( Clear Pass Guest) and navigate to "Home » Onboard + WorkSpace » Initial Setup » Certificate Authorities"

Select the Certificate Authority and click on "Edit".




Scroll down to find the Validity time of the certificate and customize it.

Thanks for the quick guide.  Do you know if the Validity Period is limited behind the scenes to 2 years?  I cannot find anything in the documentation on this but we were attempting to configure 3 year certificates and the certs were issued with 2 year expirations.  Thanks, Ben

Hi Ben,


I was able to set the Validity period to 999 days and was able to generate a client certificate which is valid from Wednesday, 30 July 2014, 12:48 PM to Monday, 24 April 2017, 1:18 PM.client certificate.png


This was tested on ClearPass 6.3.4 version. Please let us know if you have any further queries.


Thank you.

Hi Ben,

I just tested it in the lab server(CP 6.3.4) and found it working as required. I set the Validity Periiod to 1200 days and got the client certificate issued with 1200days expiration.

If you have more than one OnBoard CA in your ClearPass server, then please ensure to increse the Validity Period in the CA which is signing the client cert.
