I am trying to access a PostgreSQL 8.4 database on a remote LINUX server with Kerberos 5 tickets using GSSAPI. This works from a Windows version of pgamin3 1.10.2 , but the OSX binary version gives a “GSSAPI Authentication not supported” error. A binary download of QGIS also gives the same error, so I suspect a common libpq problem. GSSAPI authentication is working fine for SSH clients on the same machine.
