+# /etc/pam.d/common-auth - authentication settings common to all services
+#
+# This file is included from other service-specific PAM config files,
+# and should contain a list of the authentication modules that define
+# the central authentication scheme for use on the system
+# (e.g., /etc/shadow, LDAP, Kerberos, etc.).  The default is to use the
+# traditional Unix authentication mechanisms.
+#
+# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
+# To take advantage of this, it is recommended that you configure any
+# local modules either before or after the default block, and use
+# pam-auth-update to manage selection of other modules.  See
+# pam-auth-update(8) for details.
+
+# If pam_yubico.so returns PAM_SUCCESS, then pam_google_authenticator.so is skipped.
+# All other return codes are ignored and pam_google_authenticator.so is used.
+# pam_yubico.so has "forward_pass"(pam_set_item(pamh, PAM_AUTHTOK, onlypasswd)) enabled by default.

+# prime the stack with a positive return value if there isn't one already;
+# this avoids us returning an error just because nothing sets a success code
+# since the modules above will each just jump around
