Hello Airheads,

since the default certificate from Aruba was revoked, we had to import our own SSL Certificate on Aruba IAPs for the Captive Portal Authentification.

The Login has worked again after importing the new Certificate. But we now have the Problem that we get an Error for this Certificate after typing in the credentials.
The following error occurs: „Your connection is not private“ „Attackers might be trying to steal your information from securelogin.example.de“
What are we doing wrong?

Thanks for any help!

You have to click on the details of the message to see why the browser thinks that the certificate is not valid.

Thanks for your reply.
It says "This server could not prove that it is securelogin.example.de" "NET::ERR_CERT_AUTHORITY_INVALID"

.

If this is a self-signed certificate, it will never show a trusted, because clients do not trust self-signed certificates.  (Sorry, my answer was incorrect before, but somehow they would not let me edit it).

Its not a self-signed certificate its signed by Comodo 

So that error means that Comodo is not a trusted certificate authority on your computer.  Comodo should allow you to download and import its certificate authority onto your computer, and the error should go away.

The Captive Portal is having a SSL Certificate for HTTPs from Comodo too. And we dont get a error here

Yes I do

Did you change the necessary options in ClearPass?

It's covered at the bottom of this FAQ: https://community.arubanetworks.com/t5/Controller-less-WLANs/ArubaOS-Default-Certificate-Revocation-FAQ-Instant/ta-p/275814

Thanks! Its working now! :) 

The *.pem file I uploaded to the IAP had a wrong format. 
The format must be (like its written on the Link)
1. private-key
2. public-cert
3. intermediate-root-ca-file 

Somehow the IAP accepted the *.pem file with wrong format in stat of giving me an error.

Thanks to all replies!
