I know this is an old thread but, I am having the same issue. I followed the steps but I get this error:
Computer Failed to cahnge it own password
Adjust the privilege settings for 'computername' or retry with a more privileged principal.
Adkeytab return code:27
Faild: Reset Password: Default Key Tab
Any further help with this issue would be great.
I am running centrify on Mac OS X 10.11.3
Thank you,
