account that does not have a /uucico-based
login shell, or if the password is not the correct
password for that account, the connection is dropped.

ID, group ID, group set, and home
directory for that account, with the environment variables
USER and LOGNAME set to the specified
username. Login successes and failures are logged
The server prompts with login:. The
process at the other end must supply a username.
Unless the username refers to an account without a
password, the server then prompts with
Password:. The uucico process at the
other end must supply the password for that account.
All diagnostic messages are returned on the connection,
after which the connection is closed.
