I’m a British expat living in Brisbane, Australia. I was diagnosed with Lyme disease in January 2013. I work mainly as a Python developer, currently doing container security stuff for Cisco.

  1. Hi, great post by you [https://bigjools.wordpress.com/2015/05/22/saml-federation-with-openstack/]. I followed all the steps and my OKTA authentication is working. But on Horizon side I am getting an error :
    Login failed: No authentication backend could be determined to handle the provided credentials.

    I tried to debug at the location where this error is thrown and found that it is not getting the required plugin for backend authentication.

    I have added this in keystone.conf
    saml2 = keystone.auth.plugins.mapped.Mapped and

    Can you please tell me anything I am missing.

  2. Re your post on – Webex using Ubuntu LXD containers

    Great writeup. Although the video mapping worked I still couldn’t get the audio to work. I mapped my own /dev/snd devices but when trying aplay I still got the error about not finding

    The only way I’ve ever gotten audio to work in LXD was by setting up Pulaseaudio’s TCP module in the host & mapping to it from the container using export PULSE_SERVER=x.x.x.x

    Do you get audio working in LXD using the mapping you mentioned?



  3. Hey Brian. Yes sound works for me, but weirdly not in everything. I can get sound ok from Youtube, for example, but if I go to a page that uses java[script] to make sound, it doesn’t work. I’ve not figured out why yet. Have a look at my original LXC post for a tip about .asoundrc settings.

    1. “bigjools” would you mind sending me a direct email (bmullan.mail@gmail.com).. I just retired from 20 yrs at cisco working at the rtp campus where I worked with both cisco’s sdn & openstack and would like to exchange some info on lxd/lxc efforts with you… brian
