NAME
       pam_selinux - set the default security context after login via PAM.

SYNOPSIS
       session optional /lib/security/pam_selinux.so


DESCRIPTION
       In  a  nutshell,	 pam_selinux sets up the default security context for
       the next execed shell.

       When an application opens a session using pam_selinux, the shell	 that
       gets  executed  will be run in the default security context, or if the
       user chooses and the pam file allows the	 selected  security  context.
       Also  the  controlling tty will have it’s security context modified to
       match the users.

       Adding pam_selinux into a pam file could cause other  pam  modules  to
       change  their behavior if the exec another application.	The close and
       open option help mitigate this problem.	close option will only	cause
       the  close  portion  of the pam_selinux to execute, and open will only
       cause the open portion to run.  You can add pam_selinux to the  config
       file  twice.   Add the pam_selinux close as the executes the open pass
       through the modules,  pam_selinux open_session will happen last.	 When
       pam executes the close pass through the modules pam_selinux close_ses-
       sion will happen first.


ARGUMENTS
       close  Only execute the close_session portion of the module.

       debug  turns on debugging via syslog(3).

       multiple
	      tells pam_selinux.so to allow the user to select	the  security
	      context  they  will  login  with, if the user has more than one
	      role.

       open   Only execute the open_session portion of the module.

       nottys Do not try to setup the ttys security context.

       verbose
	      attempt to inform the user when security context is set.


EXAMPLE
       /etc/pam.d/some-login-program:
       auth required   /lib/security/pam_unix.so
       session	 required   /lib/security/pam_permit.so	  session    optional
       /lib/security/pam_selinux.so


CAVEATS
       Setting	the  following	line will cause the login to fail auth suffi-
       cient /lib/security/pam_selinux.so verbose
