The authentication info is such an obvious security hole
that the data is deliberately overwritten, in the client,
with the asterisks you see.

The server can log it, with a few acrobatics. I do:

plain:
    driver =            plaintext
    public_name =       PLAIN


    server_advertise_condition = ${if def:tls_cipher}
    server_prompts =    :
    server_condition =  ${acl {auth_check} {$auth2}{$auth3}}
    server_set_id =     ${if def:auth2 {${lc:$auth2}} {<empty>}}


You do realise that this data is encoded (*not* encrypted) I hope.
Human eyes still won't like it without further processing.
