I think that the doubling should be done inside the authenticator, for
example as:
plain:
driver = plaintext
public_name = PLAIN
.ifndef AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS
client_send = "${if !eq{$tls_cipher}{}{\
^${extract{1}{::}\
{${sg{\
${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$value}fail}\
}\
{\\N[\\^]\\N}\
{^^}\
}}\
}\
^${extract{2}{::}\
{${sg{\
${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$value}fail}\
}\
{\\N[\\^]\\N}\
{^^}\
}}\
}\
}fail}"
.else
<snip>
The expressions are already horrible, so we do not lose badly here.
I'd prefer this over another part of documentation that's going to be
ignored by 99 % of users anyway.
Any idea about allowing colons in auth data?
Greetings
Marc
