Re: pgsql-jdbc and ident - Mailing list pgsql-jdbc

Hello Matt,

Have you looked through the archive for ident authorizations with the pgJDBC?

If that turns up no results please post ident quthorization with the JDBC to
the server PostgreSQL forum. Else see if someone else replays that knows more.

I can duplicate your problem and have tracked the return from the initial
sendStartupPacket() in v3/ConnectionFactoryImpl to 'E' for doAuthentication().

This would imply to me that the server does not recognize the operating
system user as required in the pg_ident.conf for your user, root, to be
sqlrelay. I not sure this is even being communicated to the server from
pgJDBC for authorization with ident, in your test case.

Please also look through the manual to see if other parameters can be sent
to the server to indicate the operating system user in the connection string.

danap.
