+# Password handling #
+#####################
+#
+# If you have CrackLib installed and enabled
+#
+# Passwords will be checked against a huge dictionary and need to
+# have at least 6 characters (cracklib can't use 5). Some options
+# of cracklib modules are:
+#
+# difok		Number of characters that needs to be different 
+#		between old and new characters
+# minlen	Password minimal length
+# retry		How many times the user can try bad new passwords
+# dcredit,ocredit,ucredit,lcredit
+#		Digiti, Others, Uppercase, Lowercase characters
+#		Positive numbers marks the max number of credits given
+#		by one character class. With dcredit=5 and minlen=6, you
+#		can't use a full numeric password because more than 5
+#		digit characters doesn't count credits to achieve the
+#		minimal length
+#		Negative numbers determine that a password needs to have
+#		at least N characters
+#
+# You can see many other pam_cracklib options at pam_cracklib(8) manpage
+# 
+# Also, the "use_authtok" option for pam_unix is for working with pam_cracklib
+# in sharing the password stack. See pam_unix(8) for more details.
+#
+# If you need to use CrackLib to enforce your passwords, uncomment 
+# two statements:
+#password    requisite     pam_cracklib.so retry=3 minlen=6 \
+#			  difok=1 dcredit=5 ocredit=5 ucredit=5 lcredit=5
+#password    sufficient    pam_unix.so nullok sha512 shadow minlen=6 try_first_pass use_authtok
+#
+# --
+# A less intense option for cracklib, is:
+#password    requisite     pam_cracklib.so retry=3
+#password    sufficient    pam_unix.so nullok sha512 shadow minlen=6 try_first_pass use_authtok
+# --
+# The default is the "traditional" way without CrackLib.
+# Passwords need to have at least 8 characters. If you are using Cracklib,
+# please comment the next statement.
+password    sufficient    pam_unix.so nullok sha512 shadow minlen=8
+
+# ATTENTION: keep the line for pam_deny.so
