I have an EC2 base instance, and they usually have password authentication disable in the sshd service. They only authenticate with key. The situation I have is every time I try to ssh into another linux host that authenticate with password I get the following message:
Warning: Permanently added
'customerstg.domain.net'
(RSA) to the list of known hosts.
Permission denied
(publickey,gssapi-with-mic,password).

This file had the following settings:
I change the PasswordAuthentication from no to yes.
And that fixed the situation. I hope this helps other people.
