UI-related change to PasswordAuthentication in sshd_config file

[Nolan Hergert]

Hello SSH developers,

I spent about 2 hours today trying to track down why disabling passwords
wasn't working on my Linux <Ubuntu> machine. I would like to propose the
following change to sshd_config:60

Before:
# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication yes

After:
# Change to no to disable tunnelled clear text passwords
PasswordAuthentication yes

I had done the usual "change yes to no", but on my non-colored editor on
the server I didn't notice the additional "#" at the beginning of the line.
I know that server admins probably have a different opinion on this change,
but for new users doing basic stuff the less steps and little details the
better.

Thanks for the consideration!

Nolan
