pam_selinux — PAM module to set the default security context
In a nutshell, pam_selinux sets up the default security context for the next
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.
Only execute the close_session portion of the module.
Turns on debugging via syslog(3).
Only execute the open_session portion of the module.
Do not try to setup the ttys security context.
attempt to inform the user when security context is set.
Attempt to ask the user for a custom security context role. If MLS is on
ask also for sensitivity level.
Use the sensitivity range of the process for the user context. This option
and the select_context option are mutually exclusive.
