You might want to try running the /usr/share/centrifydc/bin/adbindproxy.pl adbindproxy script again. When you get to the step that says:
"Please specify the stock samba winbindd listen path(dir) if it is not in [/run/samba/winbindd]"
Try entering this instead of the default response:
/var/run/samba/winbindd
I ran into the same issue when upgrading from the previous CentrifyDC-Samba package to the CentrifyDC-adbindproxy-5.3.0 package with the CentOS supplied samba4, samb4-common, samba4-winbind and samba4-winbind-clients packages.
Also make sure the the centrifydc-samba daemon is set to start on boot in run levels 3,4, and 5 by running the following command:
chkconfig --level 345 centrifydc-samba on
I documented these steps in this post that was tagged as the accepted solution:
