Symptoms

Bamboo shows the following error when trying to set up Bamboo to use a PostgreSQL database:

1 Error accessing database: FATAL: Ident authentication failed for user Bamboo

Cause

This is an error that is coming from PostgreSQL.

Resolution

Trying to connect to PostgreSQL from command line shows the same error message, which means that the issue is not caused by Bamboo. Follow the recommendation from this page: edit the /var/lib/pgsql/data/pg_hba.conf file and change ident to trust, then restart postgres:

1 2 3 4 5 6 7 8 9 10 11 # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust host all all 105.52.84.50/32 trust # IPv6 local connections: host all all ::1/128 ident
