Hello,

I have a problem with postgresql 7.4 installed on Linux Ubuntu 5.04
(hoary).

I made an 'alter' command for my db users :

eg: alter user postgres with password 'postgres';
ALTER USER

but I can't connect to postgresql using :

tobini% psql -d template1 -U postgres -W
password: postgres
psql: FATAL: IDENT authentication failed for user "postgres"

Do you have an idea about this problem ?

Your pg_hba.conf file specifies IDENT authorization, and you are not
running
the command as the unix user postgres.

Check your pg_hba.conf file and the documentation on the pg_hba.conf
file:

#AUTH-PG-HBA-CONF

Use the su command to become user postgres and then run the
psql command.
