I realize that this issue is almost two years old, but I am having similar issues.
I have a fresh CentOS 7.2 install. I installed the latest version of Centrify Express 5.3.1-398. Users home directories are an NFS mount. When users log in, their UID and GID are nobody/nobody. The same user can log into a SLES or RHEL server and their UID/GID are correct.
Any suggestions?
Thank you
Daryl
