You did not answer my original question.
After making the change in the configuration file, run `sudo adreload` or restart CentrifyDC, I did not say to run agpupdate (if you are using Express, Group Policies won't work for you).
Note that you an use these tips:
To parse the contents of the centrify.conf file
$ adinfo --config
To show the client's in memory configuration parameters
$ adinfo --sysinfo config
These are from the cheat sheet: http://community.centrify.com/t5/TechBlog/TIPS-A-Centrify-Server-Suite-Cheat-Sheet/ba-p/22568
This way you know what's in the config file, vs what adclient is working with.
