I'm new to FreeBSD, so I hope I'm posting to the right list, and I know
I'm probably leaving out something important out, but oh well.

I installed FreeBSD 5.1, used cvsup to get freebsd 5.1-current,
recompiled, and now logging in locally doesn't require a password.
Neither does su. Ssh does. Membership of wheel is still verified. Is
it normal not to ask for a password, or ... ?

Here's the output of 'uname -a'
FreeBSD yellow.setec.nu 5.1-CURRENT FreeBSD 5.1-CURRENT #0: Mon Jul  7

Thanks in advance,

Matt
