Also the controlling tty will have it\'s security context modified to match the users\&. +.PP +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\&.
