Cisco WLC and OpenSSL Madness

I was trying to convert a PFX file to be used for webauth on a Cisco WLC running the latest 7.x code. I've done this several times before in past lives and expected no resistance, but I could not get the WLC to accept the PEM certificate converted by OpenSSL 1.0 from a CentOS 6.3 server.

The WLC kept reporting a "private key decode failed".

However, one stroke of luck I found this post:

The forum member recommended using OpenSSL for windows at a version <1.0. One attempt and it went beautifully, the WLC accepted the certificate!

Does anyone have any ideas? Hopefully this helps someone else.


  1. I've been struggling with this issue and changing from 1.0.1e to 0.9.8y worked! Thanks ;)
