"Permission denied (publickey)" error while doing ssh to Archlinux AMI for newly created user

This post can probably help someone because it's not documented anywhere or can't be found on google. (before I wrote on google)

Whenever there is an error like this, it's said to check that we have
RSAAuthentication yes
PubkeyAuthentication yes

in sshd_config & have proper permissions in the .ssh directory.
chmod 700 ~/.ssh/
chmod 600 ~/.ssh/*

But, it wasn't helping me in any way. As a convention, I had saved the public keys with the name "~/.ssh/authorized_keys2" while I also had the option below enabled which was preventing the required file from being processed.
# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile     .ssh/authorized_keys
Silly me, but it took a bit of time to figure this out. Hope it will help someone.
