I think you're misunderstanding what the user-mapping stuff does.
It does not silently translate the username in the connection request
to something else; rather, it checks whether a user having the given
external name is allowed to log in as a particular Postgres user.
So there's nothing particularly wrong with your config files, but your
Then, if my files are correct, why can't I connect ?
% psql --dbname=mattermost --username=mmuser
psql: FATAL: Peer authentication failed for user "mmuser"
What system user are you doing the above as?
login with postgres is OK (pg_hba.conf settings: local
all postgres trust):
% psql --dbname=mattermost --username=postgres
psql (9.5.4)
Type "help" for help.
mattermost=# \q
I can't see why I can't connect as Postgresuser mmuser.
Common issues:
1) You have more then one Postgres cluster and you are not connecting to
the one you think you are.
2) pg_hba.conf works on first match wins, so you have another line that
matches the criteria but is not pointing at the correct map.
You had it working here:

So other then adding the mapping for the dovecot user, did anything else
change?
