Hello!
I have two different programs written in C. Both programs are compilied
and linked to the same liqpq. Postgresql-7.4.7 is installed and used.
In both programs similar connections to the same database are made over
network. On the server runs postgresql-7.3.4.
In one case everything is ok and the connection to the database works.
The other program does not work fine, the error-message "Password
authentication failed for user" appears. If i change the configuration
of the server in "pg_hba.conf" from "md5" to "password", everything
works fine too.
What is the problem?!?
