Why did you change it to restore? Per the man page, restore is to temporarily restore the contexts and would be a separate entry in the PAM stack before the module that needs the original contexts, followed by a pam_selinux.so open env_params after that module to set them up again. But don't use restore unless you actually need it for some reason.
