Error installing 3rd party certificate to WLC

patoberli — Sun, 04 Jul 2021 06:41:13 GMT

Hello Together

I currently try to install a signed 3rd party certificate to my WLC running 7.0.253.3 for guest webauth. I tried various versions including the key but it always fails.

This is the debug output:

(WiSM-slot24-1) >transfer download start

Mode............................................. TFTP

Data Type........................................ Site Cert

TFTP Server IP................................... 152.96.20.12

TFTP Packet Timeout.............................. 6

TFTP Max Retries................................. 2

TFTP Path........................................ /

This may take some time.

Are you sure you want to start? (y/N) y

Error installing certificate.

Any ideas? I tried it with chaining the root and also without.

Some tests I did, but which did not help:

#openssl pkcs12 -export -in wlan-guest.domain.com.crt.pem -inkey wlan-guest.domain.com.key -out All-certs.p12 -clcerts

#openssl pkcs12 -in All-certs.p12 -out wlan-guest.domain.com.crt_ohne_chain.pem

I have not set a password.

Thanks for help

I know the frustration .. I did a blog post on this very subject .. Did you copy and paste the cert chain correctly ?

Thanks for the reply. As far as I can see it, yes I followed this. The only deviation I did, I did never enter a password. This should work too, or?

No.... Password is required. You will have to rerun the last few commands in which you put in a password.

I tried it, I hope correct?

~/Desktop $ openssl pkcs12 -export -in wlan-guest.domain.com.crt_final_chain_komplett.pem -inkey wlan-guest.domain.com.key -out All-certs.p12 -clcerts -passin pass:PASSWORD -passout pass:PASSWORD

~/Desktop $ openssl pkcs12 -in All-certs.p12 -out finalcert.pem -passin pass:PASSWORD -passout pass:PASSWORD

MAC verified OK

~/Desktop

I also set the password on the controller, but it still won't work.

Are you using OpenSSL v9.x V1.0 has some issues.

It is 1.0.1. Going to try an older version, stand by

Thanks for the help so far!

Scott Fella — Thu, 07 Mar 2013 13:58:27 GMT

Yeah... That's why. I still use the v9.8.x of OpenSSL light.

And bang, it worked!

Those are days where I simply dislike linux...

Anyway, used now openssl 0.9.8y instead of 1.0.1 and it worked now as it should.

I already deleted my tests now, but while comparing my tests, the main difference between the two openssl versions was (if I remember correct) this string here (below the BEGIN LINE), which was not written in the 1.0.x version:

-----BEGIN RSA PRIVATE KEY-----

Proc-Type: 4,ENCRYPTED

DEK-Info: DES-EDE3-CBC,309B7173122XXXXX
