Thread: Ident authentication failed without su to user

Ident authentication failed without su to user

From
jim_bowery@hotmail.com
Date:
I've created a database "bugs" and a user "bugs" (postgresql user as
well as unix) and even made user "bugs" not require a password but I
still get this:
[root@marathon bugzilla-2.20]# psql bugs bugs
psql: FATAL:  Ident authentication failed for user "bugs"
...
but if I
[root@marathon bugzilla-2.20]# su bugs
[bugs@marathon bugzilla-2.20]$ psql bugs bugs
Welcome to psql 8.0.7, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
     \h for help with SQL commands
     \? for help with psql commands
     \g or terminate with semicolon to execute query
     \q to quit

bugs=>

it works.  any ideas why?

Because 'ident sameuser' means your Unix username has to be the same
as your PG username.  Note that 'root' != 'bugs'.

Probably because of your pg_hba.conf file. The first option is most
likely 'ident'.

You probably want it as 'md5' (the file itself has tons of documentation).

Order does matter in that file - it will use the first rule that applies.

Yes.  It turns out the problem was that my pg_hba.conf file was
replaced by another file during a yum install of the new postgresql but
in a different path.  When I used "locate pg_hba.conf" it returned the
path of the old file which didn't have the 'ident sameuser' rule.
