Certificate error in IE for WLAN web-auth

Hello guys.

i just set up an enterprise wireless network with guest access using 2 WiSMs (code as internal controllers and 2 5508 WLCs (code as guest anchor controllers. i am using web-auth for the guest wlans and everything works just fine.

we purchased a Verisign certificate and downloaded it to the guest anhor controllers for the web-auth login page and for some reason, we get an invalid certificate error prompt from Internet Explorer while Firefox comes up just fine from the same client.

please i will appreciate suggestions on how to crack this.

thanx in advance for the help

The error that pops up in IE should say way it failed.  What is the reason listed in the error?

Re: Certificate error in IE for WLAN web-auth

the error we get in IE is the standard security warning saying "there is a problem with this website's security certificate. the security certificate presented by this website was not issued by a trusted certificate authority" as mentioned earlier, the cert was issued by Verisign

Re: Certificate error in IE for WLAN web-auth


i got a solution to this the moment i discovered that verisign stopped issuing  unchained certificates years ago. here's how i went  about it:

1. i downloaded openssl, generated the csr and submitted  to verisign.

2. i copied the digital certificate from verisign in  x509 format.

3. i downloaded the root CA certs and intermediate  CA cert files from verisign for the class of certificate we ordered (secure  server g2)

4. i combined the files as per cisco instruction and  converted to .pem using openssl.

5. i downloaded the cert file to  the wlc via cli and reset the controllers.

hope someone finds this useful
