problems after installing certificate 2500 series


i have problems installing an 3rd-Party signed certificate to my Cisco 2504 ( AIR-CT2504-15-K9 ).

The certificate should be used for WebAuth, because of the annoying SSL errors in browser.

Software Version       

License Level base

WebAuth : https

WebAdmin : https

W-Lan : working with Localy Generated Certificate

Virtual IP :

Virtual IP DNS :

I used the following manual :

According to the manual, I used OpenSSL : 0.9.8o

My certificate is a wildcard-certificate like *

I did following to get it :

# openssl req -new -nodes -newkey rsa:2048 -keyout -out

> Signing Request @ Thawte

< got my signed certificate ( server.crt ) with instructions to use intermediate certificate ( bundle.crt )

# openssl pkcs12 -export -in server.crt -inkey -certfile bundle.crt -out CA.p12 -clcerts -passin pass:check123 -passout pass:check123

# openssl pkcs12 -in CA.p12 -out CA.pem -passin pass:check123 -passout pass:check123

After generating the CA.pem, i downloaded it to the controller ( CLI & WebInterface ).

The Controller installed it without an error and wanted to restart the system. After saving & reseting the system I was not able to get onto the management Interface anymore. The browser did not connect to the WebAdmin anymore. The proper working W-Lan wasn't working anymore too. When I tried to connect, the connection broke with an error.

Using "show certificate summary" i got following :

Web Administration Certificate................... Manufacture Installed

Web Authentication Certificate................... 3rd Party

Certificate compatibility mode:.................. off

When i reset my WebAuth Certificate, the W-Lan and the WebAdmin are working again.

Can anyone help me, to solve my problem ?

Best regards

First off, you need to be able to to the your VIP.  This needs to be resolved by the DNS servers that the clients will be getting.  So you either using your internl, external or ISP dns server.  Are you uploading the certificate in the correct spot.  Here is the location on the image

You are right, i forgot to say it... will resolved by clients to For testing, I registered this subdomain in our public DNS of

Yes, i up/downloaded it in the right spot.

I'm suprised, that the WebAdmin isn't working... cause "show certificate summary" says, that the WebAdmin Certificate is the manufactured certificate ...

Problem solved ...

On converting TO pkcs12 i se t"-passin pass:check123" ... but my key had noch pass ...

So, doing the first convertion without this parameter, the Cisco is now working with the cert.
