Mounting a subdirectory of a Samba Share isn't possible with the updated binaries on Cent OS 7 anymore. We need this option for autofs mounting just subdirectories for specific users. 

[pb@extrasrv1 ~]# rpm -qa | grep samba

We are still able mounting the share with older binaries in CentOS 6. Please let me know if I am able to serve with further details.
