Hi "Show your psql command that is failing."
[root@~ pg]# /usr/local/pgsql/bin/psql -p5432 -d db1 -h127.0.0.1 psql: error: connection to server at "127.0.0.1", port 5432 failed: FATAL: Ident authentication failed for user "root" If the error is Ident authentication failed for user "cce", i think the ident config file taked effect. Reference information: PG version 15.3 Thanks. ________________________________ 发件人: David G.

In short, the mapping is useless. David J.
