If you had set the same password in the postgresql server for the user and in 
the pgbouncer local unix user it should work.
What are the contents of your /etc/pam.d files?
How do /etc/pam.d/other /etc/pam.d/common-auth /etc/pam.d/common-account look 
like?
How about data/pg_hba.conf ?

Also try to do your tests by tail -f :
* the pgbouncer log
* linux auth.log or equivalent
* the pgsql log
and watch them for every enter you press.

You might have to tweak data/pg_hba.conf as well in order to look for md5 
passwords for this user from the pgbouncer machine.

    ok, pgbouncer should be able to read /etc/pam* files.
    Did you miss the

        Okay, thanks for the response. Unfortunately Aurora does not expose 
these files or I should say there is no concept of these files in AWS managed 
Aurora DB service. Anyway I will give a try
        and let you know.

            Achilleas, for this setup to work are changes to postgresql.conf

            Those files are needed in any case if you work with postgresql. 
Unfortunately no experience with Aurora. He have been building from source for 
ages.

                Right, I had written a blog about it :
                
https://severalnines.com/database-blog/one-security-system-application-connection-pooling-and-postgresql-case-ldap

                However, I always wished (since my first endeavors with 
pgbouncer) it was less complicated.
