+Add concatenated two-factor authentication to YubiPAM.  This allows a
+work-around for arguably broken PAM clients that only look for one password
+field.
+
+Regular two-factor authentication is achieved by adding the 'two_factor'
+parameter to the PAM module in the appropriate /etc/pam.d file.  The "passcode"
+is then set for each user when enrolling by specifying -c to ykpasswd.
+
+i.e.
+	somewhere in pam.d:
+
+	auth sufficient pam_yubikey.so two_factor
+
+	then:
+	# ykpasswd -a -c -f ffeeddccbbaa -k afaa...
+
+	The -c tells ykpasswd to ask for a passcode.
+
+When logging in, the system will now ask for the OTP, followed by the
+"passcode".
+
+This patch extends the two-factor authentication to provide the concatenated
+two-factor feature.  Where your PAM configuration specifies 'two_factor', change
+this to 'concat_two_factor'.  Now, YubiPAM instead now asks for
+'Password+YubiKey OTP'.  You enter them in this order separated by a single
+space.  This method is compatible with single-password PAM clients such as KDM.
