pam_selinux(8) -- Linux man page
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_session will happen first.
