Good morning.<br>
<br>
I was just reading <a class="moz-txt-link-freetext"
href="https://wiki.dovecot.org/AuthDatabase/LDAP/PasswordLookups"
moz-do-not-send="true">https://wiki.dovecot.org/AuthDatabase/LDAP/PasswordLookups</a>
and found the following statement<br>
<blockquote type="cite">When using <a
href="https://wiki.dovecot.org/LDA" moz-do-not-send="true">LDA</a>
and static userdb, deliver can check if destination user exists.
With auth binds this check isn't possible.</blockquote>
<br>
Is this still relevant? Is there a workaround? It seems like using
dovecots lmtp in an active directory environment is not possible,
is this correct?<br>

<p>You cannot check user existence with auth binds because auth bind
requires user credentials.</p>
<p>This is why I suggested you use a "service user" in LDAP to
perform the database lookups instead of auth binds. You can still
authenticate your users using kerberos.<br>
