Re: What does error "psql: Kerberos 5 authentication not supported" means?

Hi,

I'm not quite sure but it probably means that postgresql was not built with kerberos 5 support.

That would make sense if  you are using a binary install (did not compile from source), because of the notice at http://www.postgresql.org/docs/9.0/interactive/auth-methods.html#KERBEROS-AUTH

"Note: Native Kerberos authentication has been deprecated and should be used only for backward compatibility. New and upgraded installations are encouraged to use the industry-standard GSSAPI authentication method (see Section 19.3.3) instead."

Hi Guys,

I tried to setup kerberos authentication with postgresql 8.4.7 on Ubuntu 10.10.

When I use:
$ psql –h ubuntu.server –U gavin  dbname

I get following error:
psql: Kerberos 5 authentication not supported.

And from the server side of postgresql, I could see following log:

What does this means and how could I get more verbose logs?

Besides, is there any more howto/doc on integrate kerberos and postgresql besides the official documentation at http://www.postgresql.org/docs/9.0/interactive/client-authentication.html?


Thanks very much in advance!

Regards,
Yandong
