Connection Issue

[Andy Hartman <hartman60home@xxxxxxxxx>]

I'm using a Powershell script to connect to a remote 16.3(windows) version of the DB. 

Add-type -path 'C:\Program Files (x86)\PostgreSQL\Npgsql\bin\net451\Npgsql.dll'

# Define connection strings for MS SQL and PostgreSQL

$pgsqlConnectionString = "Host=xxxxxx;Port=5432;Username=xxx;Password=xx;Database=xxx;"

# Create connection to PostgreSQL

$pgsqlConn = New-Object Npgsql.NpgsqlConnection

$pgsqlConn.ConnectionString = $pgsqlConnectionString

$pgsqlConn.Open()


When this statement hits I get an error:

Exception calling "Open" with "0" argument(s): "Authentication method not supported (Received: 10)"

Any ideas?

Thanks.
