Automount and NIS+
A common problem with auto_home is that systems in a NIS+ environment may create user accounts on a file system mounted as /home. This means that if auto_home is active, as defined by /etc/auto_master, then after rebooting, the shared home directories are mounted on /home, and when the local /home attempts to mount the same point, it fails. This is one of the most frequently asked questions about Solaris, as the convention was different for earlier Solaris systems, which used local /home directories. The recommended practice is now to create home directories under /export/home, on the local file system if required, or to use auto_home in a NIS+ environment. However, if you wish to disable this feature altogether, and stick with a local /home, then simply remove “+auto_master” from the master map (/etc/auto_master).
