typo in Ch 37, dovecot authenticator?

http://www.exim.org/exim-html-current/doc/html/spec_html/ch37.html

The text says "the identity of the user who authenticated is placed in
$auth1", but the example show use of both "$auth1" and "$auth2".

Does someone know offhand which is correct (to save my lazy self from
finding out experimentally)?

TIA!

Both. Depends on public_name being used. For PLAIN, username is stored
in $auth2 and password in $auth3. For LOGIN, username is $auth1 and
password in $auth2. For NTLM I have no idea.

If using Dovecot authentication with Exim, note that Exim will abort if
authenticating against Dovecot 2.0. See this post:

I was tempted to experimented and $auth1 is indeed correct. The examples
are valid for other authentication drivers (see my previous reply).

Thank you for this pointer!

The same is also true for:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch36.html

The wording in the docs (and the source) says $auth1, while examples use
$auth1 and $auth2.

I apologise for three separate posts.

I'm not quite clear which way round you're doing the authentication here,
but if you want senders connecting to exim to be authenticated from
Dovecot, then I have recently written a HOWTO that includes a section on
doing just that. See:
