       pam_console - control permissions for users at the system console

       session optional /lib/security/pam_console.so
       auth required /lib/security/pam_console.so

       pam_console.so  is  designed  to give users at the physical console (virtual terminals and
       local xdm-managed X sessions by default, but that is configurable) capabilities that  they
       would  not  otherwise  have,  and  to  take those capabilities away when the are no longer
       logged in at the console.  It provides two main kinds of  capabilities:	file  permissions
       and authentication.

       When  a	user  logs in at the console and no other user is currently logged in at the con-
       sole, pam_console.so will change permissions and ownership of files as  described  in  the
       file  /etc/security/console.perms.   That user may then log in on other terminals that are
       considered part of the console, and as long as the user is still logged in at any  one  of
       those  terminals,  that	user  will own those devices.  When the user logs out of the last
       terminal, the console may be taken by the next user to  log  in.   Other  users	who  have
       logged  in  at  the  console during the time that the first user was logged in will not be
       given ownership of the devices unless they log in on one of the terminals; having done  so
       on  any	one terminal, the next user will own those devices until he or she has logged out
       of every terminal that is part of the physical console.	Then the race can start  for  the
       next  user.   In practice, this is not a problem; the physical console is not generally in
       use by many people at the same time, and pam_console.so just tries to do the  right  thing
       in weird cases.

	      tells pam_console.so to read the table of configured filesystems from a file  other

	      device names.
