Change Metadata Store Authentication to MD5

If you installed Composer's metadata store on a server running CentOS or RedHat, complete the configuration steps below. If the server is running Ubuntu, ignore these instructions.

Note: New installations of Logi Composer (v24.3 and later) use PostgreSQL 16. If you are upgrading your environment to v24.3 or later, you can retain your existing PostgreSQL version.

Change authentication for your metadata store to MD5

1. Edit the pg_hba.conf file for the appropriate version of PosgreSQL.

   sudo vi /var/lib/pgsql/12/data/pg_hba.conf

2. Change METHOD to MD5.

   # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5

3. Restart PostgreSQL. In CentOS environments, run:

   sudo systemctl restart postgresql-12
