Authentication with PGSQL

Hi,
With PGSQL you can authenticate with KRB5 or a proprietary /etc/passwd
Is it planned to use other methods of authenticating?
LDAP?
PAM?
SASL?

I'm in the process of centralizing authentication of users for all our
services but it's not possible in the current state of PGSQL.

Thanks for any idea
