display certificates revoked randomly on some laptops

[lawrence123]

Hi,

I am currently facing the "securelogin.arubanetworks.com" certificates has been revoked when i open the IE browser. This occurs only to some randomly chosen laptops.

On the other hand, I have also taken some other laptops to test and they are   able to pass the certificate  without any issues. No sign of certificate revoked.  After the authentication, it goes to the next screen which is the guest wifi login screen. for those pass the authentication. On those that have no error,  I have checked that the certificate is still valid till Aug 2017.

All laptops have the same IE versions.

I am curious and confused why it occurs and affects only some laptops, while the rest of the laptops are able to pass through(no certificate revoked diplayed) .  

Apprreciate and thanks for your help in advance

Best practice is to replace it with a third party cert using "securelogin.yourdomain.com"

Not all browsers perform realtime revocation checks.

You should not be using the default controller certificate.
