We don't use the passwords from /etc/passwd for two reasons. First of
all, Coda uses a shared secret based authentication scheme, so the auth2
daemon likes to know your plaintext password. We could let the 'shared'
secret be the crypted & salted version of the password, but you would
then need to use shadow passwords as everyone can read this secret then
from /etc/password.

The second reason is that Coda doesn't employ strong encryption as is,
but merely obfusticates things using a simple XOR encoding. By grabbing
a couple of clog-auth2 authentications, it really isn't that hard to
find the password.

Right after giving the name of the Coda administrator a message was
displayed that the admin password was set to "changeme".
