Hi guys and girls,

I have a problem..
I am using a TPQConnection on a form and when i put the Connected
option on the Property box on 'True', appears a box with the following
error:

PQConnection1: Connection to database failed(PostgreSQL:fe_sendauth:
authentication type 5 not supported)

can somebody help me? Please?

I have postgresql installed on my machine and i am trying to connect
to a database locally...

All answers are very welcome

what version of postgres do you have installed as it sounds like a
version conflict

I've installed the 2.2.4 version of Free Pascal...

What version of Postgres? Version 8.x, 9.x? You have to be specific.

It would be a good idea to upgrade to the latest stable Lazarus vesion
(0.9.30 with FPC 2.4.2).

Like eny said, update your version of Lazarus & try to connect to your
database again.
