What are you trying to do here? Log in with your admin credentials, or
create a new user?

If you are trying to log in for the first time, the default password
would be set to 'changeme', and you probably would want to log in using
'clog vandys_at_my.local.realm'

If you are trying to create a new user then you have to first add the
user's identity in the pdb database (essentially Coda's version of
/etc/passwd and /etc/group) and once that is done you can activate the
account and set a password with au nu.

On the server run,

    pdbtool nu vandys

And then on the client,

    au nu
    Your vice name: admin
    Your password: admin_password
    New user name: vandys
    New user password: whatever

When rpc2 is unable to validate the checksum of the incoming packet it
complains loudly. When the wrong password is typed, it will also fail to
validate because don't actually send the password across the network,
but try to decrypt incoming packets based on a hash of the password.
(and with an incorrect password the key is wrong).

So it isn't really an RPC2 error, it is just that that is the place
where it is detected.
