Hello again! I've been setting up my PostgreSQL server by doing something I've never done before: I've joined a Linux server to a domain so I can use integrated Kerberos authentication from server to server. I've managed to make this work from Linux machine to Linux machine. On the client, I retrieve my Kerberos ticket with kinit, and then I can use psql with my username to connect to the server without a password over GSSAPI. So far, so good. However, the eventual goal was to connect to this same server from a .NET app running on Windows, and here I've run into a snag. The Npgsql library does not support GSSAPI—it only supports SSPI, which is nearly-but-not-enough-like the same thing to count in this situation, because I can't seem to configure my PostgreSQL on Linux to accept SSPI. If I try it, I get the error: invalid authentication method "sspi": not supported by this build The docs say that SSPI is supported if GSSAPI is available (http://www.postgresql.org/docs/9.3/static/auth-methods.html#SSPI-AUTH). Is this just a matter of me running the wrong build? I'm using PostgreSQL 9.3 from the official builds for Debian 6. If the docs are wrong, and SSPI isn't available server-side on Linux, what are my other options? —Brian -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
