Controller Web Gui Certificate Error

    Hello, thank you as always for your lightning fast help.  Currently when we access out Aruba 7210 controller management web gui we get the https "site is not private, cert is not verified" error.  See screenshot below.  In the dropdown, which cert do I need to replace to get rid of this error (Server Cert, Public Cert, etc)?  Will this affect wifi clients when I replace this cert?  We have a godaddy wildcard cert I was going to use....any pitfalls?  Thanks.

    You would use the server cert option and then select it under Management > General > WebUI Management Authentication Method certificate. You can use a wildcard for the web UI but you cannot use it for 802.1X authentication.

     

    Keep in mind that you'll need to create a DNS entry for the certificate to work correctly.

    Thanks again.  The controllers are not terminating radius.  Could I use the wildcard cert for the controllers but then a non-wildcard cert for clearpass?  Hope that makes sense, thanks!

    Yes, the controller certificate is separate from the ClearPass certificate.

    From GoDaddy I have the following files:  

    • mywildcard_bundle.crt
    • mywildcard.p7b
    • mywildcard.crt
    • mywildcard.key
    • mywildcard.pem
    • mywildcard.pfx

    Any idea which one I should import and which format I should choose from the Aruba controller dropdown (DER, PEM, PFX, etc.)  I don't know what these different file formats signify and what is Aruba best practice, thanks.

    Update, I imported the .pem to the Aruba controller "server certificate" but when I got to manage my controller at the web gui I still get the https not safe error in my browser.  Here's some details from the error:  NET::ERR_CERT_COMMON_NAME_INVALID   

    Subject: securelogin.arubanetworks.com

    mycontroller.mywildcardomain.com:4343 uses an invalid security certificate. The certificate is only valid for securelogin.arubanetworks.com (Error code: ssl_error_bad_cert_domain)

     

    Can anyone explain what is going on here?  I don't know what mywildcarddomain.com has to do with securelogin.arubanetworks.com....this is frustrating.

    Did you configure the controller to use the new cert for management?


    Thanks,
