issues a password prompt. Enter the same password twice (for verification purposes).
\fBauthpasswd\fR
computes and prints the encrypted password. The encrypted password can be inserted verbatim into the appropriate account record that's processed by the authentication library's
authmysql,
authpgsql, or
authldap
module.
