Clearpass Guest self-certificate issue

  • 1.  Clearpass Guest self-certificate issue

    Posted Dec 28, 2020 11:45 AM

    Dear Arubers,


    I am writing to you about a problem encountered on CP server and IAP access points.

    I am configuring ClearPass server and I am having a strange certificate issue. After the automatic redirection to GUEST portal, a certificate error si shown. If we look at the certificate used, we find a certificate issued for « ».

    However, on access-point, the Default CP server certificate is « ». On Clearpass configuration, I changed the the HTTPS certificate (with a public authority) and let the GUEST default address « » 

    So, I don't understand why this message is shown. Could you help me to fin a solution for this issue ?


    Thanks for your help :)

    it seems your redirection is not working maybe some wrong config on the iap captive portal profile

    please could you share some screen from the iap

    You need to replace the certificate on IAP (and also change setting on ClearPass ( -> certificate of the IAP)
