Обсуждение: Logging authentication requests with GSSAPI

Hello,

I'm authenticating to postgres using GSSAPI and (for audit reasons) I
need to be able to log the principle name that connects as well as the
username it is mapped to. Is there any way I can get postgres to log
this without cranking up the log level for everything?

Thanks very much ,
Joshua Warburton

Not easily, I don't think.  The Kerberos logs should be able to tell you
every postgres/HOST@REALM ticket which is issued and while that's not
great it's at least something.

Another option is to just use the full princ *as* the PG username, which
works fine but can be a bit annoying when you're trying to GRANT
permissions, etc (I'd suggest using a lot of roles :).

Improving this has been one of those things that I've wanted to do for a
long time...  Probably by just adding the "System Username" or similar
to the "connection authorized" log message.  Would that work for your
need..?

    Thanks,
