You can use SSPI if you're connecting from Windows to a Windows-hosted PostgreSQL server in a domain or on a the same machine (I actually verified that works yesterday), or you can in theory use GSSAPI to authenticate to a Linux hosted server if you're on a Linux client (I'm working on verifying that at the moment). Once I've got those scenarios working and verified, I'll move on to figuring out how to handle Windows/Mac clients connecting with GSSAPI. Note that SSPI/GSSAPI will require that you're running pgAdmin in Desktop mode. It will not work in Server mode (because the server will typically be running under a different user account). There's a feature request for that in the backlog. -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EDB: http://www.enterprisedb.com
