Alex: To troubleshoot, try su’ing to the httpd user, and then, as the httpd user, try accessing your database with “psql testp_development” . Try the psql commands above to list databases, etc. Don’t forget to GRANT the privileges to the httpd user that you need. Reread the sections above on PostgreSQL users, and the psql commands.

I have a problem with postgresql ident authentication.
I installed apache, ruby on rails and passenger.
I use ident authentication and i got “MIdent authentication failed for user “httpd”.
I added httpd user to postgresql users. But it does not help.
Here is my database.yml
development:
adapter: postgresql
encoding: unicode
database: testp_development
pool: 5
username: httpd
password: 12345
I know that problem is in ident authentication.
Here is pg_hba.conf

TYPE DATABASE USER CIDR-ADDRESS METHOD

# “local” is for Unix domain socket connections only
local all all ident sameuser
# IPv4 local connections:
host all all 127.0.0.1/32 ident sameuser
# IPv6 local connections:
host all all ::1/128 ident sameuser

Please help me.

Yes, mihserf: you can use su to change to the postgres account either from root (without a password) or from another user (with a password). There are pros and cons to doing it either way; use whichever you are more comfortable with.

Thanks for the article!
When I tried to su postgres I had authentication error cause of wrong password.
To fix it you need to do sudo passwd postgres and then type your new password twice.
Now you can simply change user to postgres by command su postgres and typing your password.
Maybe someone will find it helpful.

Thanks, Boris. Yes; everything above was with Rails 2.2.2 . I had not tried it with Rails 2.1

Thanx so much, I’ve been having problems with Postgre, It worked with Rails 2.1 but it is not working with Rails 2.2. Did you make it work PostgreSQL with Rails 2.2
