New description:

 I'm following the MacPorts guide to set up dovecot user and password
 databases on Mojave, wiki:howto/SetupDovecot for a multi-user system. I am
 able to authenticate successfully, and {{{doveadm user myusername}}} works
 for all accounts.

 However, dovecot's {{{mail-err.log}}} shows setuid issues when multiple
 users are logged in:

 {{{
 May 21 22:28:46 imap(pid 17441 user myuser): Fatal: setuid(512(myuser)
 from userdb lookup) failed with euid=501(adminuser): Operation not
 permitted (This binary should probably be called with process user set to
 512(myuser) instead of 501(adminuser))
 }}}

 I do not see the cause pf the issue. I've double checked everything and
 have not used either {{{myuser}}} or {{{admin}}} user in dovecot's
 {{{/opt/local/conf.d}}} or indeed anywhere in {{{/opt/local}}}.

 My {{{passdb}}} {{{userdb}}} blocks are simple:

 {{{
 passdb pam {
   driver = pam
 }

 userdb passwd {
   driver = passwd
 }
 }}}
