Re: BUG #10680: LDAP bind password leaks to log on failed authentication

Thanks for the reply.

Sadly, all other authentication options will not work for us.

I'm not seeing the user password in the log, I'm seeing the bind
password (ldapbindpasswd) that in the pg_hba.conf file. There is a
line in auth.c that, on every failed attempt, prints the full (raw)
configuration line to the log at all log levels. So, this isn't just
a problem with LDAP (with ldapbindpasswd) but also the RADIUS method
(radiussecret).

I've submitted a patch and we're discussing the problem further on the
pgsql-hackers distro. Really, I think it all comes down to finding
the right balance of security and convenience of the administrator.
I'm hopeful we'll come up with the right answer soon and I can submit
a new patch.
