PAM_SELINUX(8) Linux-PAM Manual PAM_SELINUX(8)NAMEpam_selinux - PAM module to set the default security context
SYNOPSIS
pam_selinux.so [close] [debug] [open] [nottys] [verbose]
[select_context] [use_current_range]
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_session will happen first.

close Only execute the close_session portion of the module.
debug Turns on debugging via syslog(3).
