HI,
I'm also having the same issue with my client when I try to adjoin. I am joining a CentOS 7 workstation to AD using Centrify.
I used Deployment Manager to do this.
I get this in the issues log (Event History)
------------------------------------------------------------------
Error executing /var/centrifydm/tmp/adjoin.cmd.1003.
DC: 5.4.3-887
Login authentication for user 'nbona' successful.
---------------------------------------------------------------------
I do have sudo rights so thats cleared. Can you please help
