Did you reload the server after making the changes?:

https://www.postgresql.org/docs/9.6/static/auth-pg-hba-conf.html

The pg_hba.conf file is read on start-up and when the main server
process receives a SIGHUP signal. If you edit the file on an active
system, you will need to signal the postmaster (using pg_ctl reload or
kill -HUP) to make it re-read the file.

The pg_ident.conf file is read on start-up and when the main server
process receives a SIGHUP signal. If you edit the file on an active
system, you will need to signal the postmaster (using pg_ctl reload or
kill -HUP) to make it re-read the file.
