Autofs Security Restrictions

The –nosuid option prevents users from creating files with the setuid or setgid bit set.

This entry overrides the entry for /home in a generic local /etc/auto_master file. For information about the generic local /etc/auto_masterfile, see Setting Up a Common View of /home. The override happens because the +auto_master reference to the external name service map occurs before the /home entry in the file. If the entries in the auto_home map include mount options, the –nosuid option is overwritten. Therefore, either no options should be used in the auto_home map or the –nosuid option must be included with each entry.


Note -  Do not mount the home directory disk partitions on or under /home on the server.
