Certificate problems during login to ArubaOS in Student Lab Environment

Certificate errors during login to Student Lab ArubaOS Controllers this one from Microsoft's Edge browser.

This can happen with any browser depending on the state of your controllers server certificate.

First you should try to click the bottom link that says:

"Continue to this webpage (not recommended)"

This will try to bypass the fact that your browser might not trust the signing authority of the CA that signed the certificate used for SSL by your Controllers web server.

If you are using the default certificate included in the ArubaOS firmware, it may be a revoked certificate, and if your browser has determined that, you may not be able to continue to the web site unless you disable certificate checking altogether on your browser.

Warning: it is NOT recommended to disable certificate checking in the real world, but doing so on a temporary basis for LAB environment only is an acceptable short term solution to finish your labs.

How to disable Certificate checking (ONLY FOR LAB ENVIRONMENTS)

Microsoft Edge

• refer to this link from Microsofts web site
• I do not recommend this method however as it is a permanent change to your browser, requires a reboot to take effect, and you may forget to enable cert checking later which could be disastrous to your cyber security.

Chrome Browser

• Chrome allows you to disable certificate checking with a command line option, this is ideal as it will not effect you next time you use your browser, making is a simpler and safer option.
• Start Chrome with the "--ignore-certificate-errors" option as shown below:

C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ignore-certificate-errors
