Hi to all! I have following systems: 1. Local machine with Windows XP SP2 and PostgreSQL 8.2 - test system. 2. Work server in local network (FreeBSD + PostgreSQL 8.2) - work system. I write client with Delphi 7 IDE and use Zeos Lib 6.6.2 (http://zeos.firmos.at/) for database access. When I tried to connect to server I recieve error message: "SQL Error: fe_sendauth: authentication type 5 not supported." After searching in internet I found solution: set authentication method "password" instead of "md5". In file pg_hba.conf on local machine I wrote: # TYPE DATABASE USER CIDR-ADDRESS METHOD host all all 127.0.0.1/32 password and on server: # TYPE DATABASE USER CIDR-ADDRESS METHOD host all all 192.168.3.0/24 password My IP-address in local network is 192.168.3.16... After that I can to connect to test PostgreSQL server on localhost, and connection works fine, but attempt to connect to work server finishes by same error message "SQL Error: fe_sendauth: authentication type 5 not supported." I tried to place string in pg_hba.conf on first and last positions, wrote names of databases and users instead of "all" but it doesn't work. As I understand, my main problem is to force PostgreSQL server allow me to connect with password authentication method, isn't it? And how I can do that? P. S. Sorry for poor english...
