# Configuration file for Pluggable Authentication Modules (PAM).
#
# This file controls the authentication methods that login and other
# utilities use.  See pam(8) for a description of its format.
#
# Note: the final entry must say "required" -- otherwise, things don't
# work quite right.  If you delete the final entry, be sure to change
# "sufficient" to "required" in the entry before it.

# If the user can authenticate with S/Key, that's sufficient; allow clear
# password. Try kerberos, then try plain unix password.
