Typically, the user accounts that are created as ZFS file systems do not need to be manually mounted. With ZFS, file systems are automounted when they are created and then mounted at boot time from the SMF local file system service.
When creating user accounts, make sure home directories are set up as they are in the name service, at /home/username. Then, make sure that the auto_home map indicates the NFS path to the user's home directory. For task-related information, see Autofs Administration in Managing Network File Systems in Oracle Solaris 11.3.
If you need to manually mount a user's home directory, use the zfs mount command. For example:
# zfs mount users/home/jdoe
