Welcome to the Centrify Express forums.
Note that the functionality of provided by Centrify is working as expected based on your feedback.
Some background - Centrify uses 2 well-known UNIX frameworks (Name Service Switch for user and group resolution and Pluggable Authentication Modules for AuthN) and Kerberos as the authentication protocol.
This means that your application (in this case ecryptfs and its utilities) must be compiled to support those frameworks.
Please verify that's the case before you move forward and that you're properly configuring those options.
If you don't know what NSS and PAM are, further investigation and testing is required on your end.
We'll be here to help.
