Shows that auth is not honouring the %n i have. Does the username_format need to be only in the userdb section or also the passdb part?

That was done for testing to see if it made any difference when I moved to LDA, in LDA mode it seems to not care if that is %n or %u, it always takes the first part of the email address which is weird. Ive just tested again to confirm on %n and its not working so ive reverted again back to LDA which does. Seems to not matter how that variable is set it does not do anything.

When using %n ive tried to see if I can login via IMAP with the whole username but again no, this is the error, note the difference between the 'user' field on each line.

Hi Ricardo,

I seem to miss something: You are talking about LMTP and LDA, then present a log of an IMAP login attempt. Neither LDA not LMTP should need any authentification, where should the password come from? And yes, for auth you will need %n in passdb, too. username_format is not documented for passdb { driver = pam}, but you could try.

Could you post a log of a LMTP delivery, when %n is in effect _and_ you are sure have reloaded Dovecot?

userdb { args = username_format=%u /etc/passwd driver = passwd-file name = passwd-file }

In opposite to your sentence I see a %u there.
