Merge lp:~kotux/serverguide/pass-length into lp:~ubuntu-core-doc/serverguide/saucy

[John Kim]

I confirmed the correct parameter name for setting minimum password length and updated it. According to lxc saucy, /etc/pam.d/common-password shows success=1, not 2.

[Doug Smythies (dsmythies)]

I'm not a subject matter expert for this one, but doesn't the success number depend on ho many entries there are? Example:

# here are the per-package modules (the "Primary" block)
password [success=2 default=ignore] pam_unix.so obscure sha512
password [success=1 default=ignore] pam_winbind.so use_authtok try_first_pass

Anyway, I suppose it doesn't matter in this context, as long as the example is correct.

 	By default, Ubuntu requires a minimum password length of 6 characters, as well as some basic entropy checks.  These values are controlled in the file <filename>/etc/pam.d/common-password</filename>, which is outlined below.
