INFO: "Certificate has expired" error with web-based authentication

  • R3000

Question:

"Certificate has expired" error with web-based authentication

Reply

To fix the "This certificate has expired" warning you might get when using web-based authentication with the R3000's built-in SSL certificate:

Go to System -> Authentication -> Authentication SSL Certificate

Go to Download/View/Delete Certificate; click "Delete"

Go to Self Signed Certificate; click "Create Self Signed Certificate"

The new certificate should now be good for several more years.

---

If you're getting a "Certificate Error" warning page, or "The certificate is not trusted because it is self signed"...

You are seeing this message because your web browser doesn't have the self-signed certificate in it's list of trusted root certificates.  There are two things you can do:

1.  Import/Install the R3000's certificate into your web browser's trusted certificates.  If you're using Active Directory, this can usually be done to all the workstations at once using Group Policy.  

2. The second option is to purchase a commercial certificate from Verisign, Thawte, or any company that's already in your browser's list of Trusted Root Certification Authorities.  You can view this list in IE by going to Tools -> Internet Options -> Content -> Certificates -> Trusted Root Certification Authorities.  If you go this route, try to purchase a Trusted Root Certificate, instead of a "chained certificate" or "intermediate certificate."  Although, if you go with the latter, we can install it for you from the back-end.
