Hi;

I have set up a windows domain trying to run Postgres client using SSPI. I've reached a point that I can use psql to login from my client machine without specifying username and password. But everytime I ran my .NET client program on a domain computer other than the database server itself, I got following error messages. And the program works without error on the database server itself. Any help is much appreciated!

Message:FATAL: XX000: could not accept SSPI security context
BaseMessage:could not accept SSPI security context
Detail:The token supplied to the function is invalid
(80090308)
Source:Npgsql
TargetSite:Boolean MoveNext()

My code is very simple:

NpgsqlEventLog.Level = LogLevel.Debug;
NpgsqlEventLog.LogName = "NpgsqlEventLog.txt";
NpgsqlConnectionStringBuilder pgsqlCSB = new NpgsqlConnectionStringBuilder();
pgsqlCSB.Database = "test";
pgsqlCSB.IntegratedSecurity = true;
pgsqlCSB.Host = "VM-WIN2008";
pgsqlCSB.Port = 5432;
NpgsqlConnection pgsqlConn = new NpgsqlConnection(pgsqlCSB.ConnectionString);
pgsqlConn.Open();
DataTable dt = pgsqlConn.GetSchema();
