ssh not working

[frezbo]

This is my config file:
vault_addr = "http://10.16.1.9:8200"
ssh_mount_point = "ssh"
tls_skip_verify = true
allowed_roles = "*"

when using vault ssh -role otp_key_role ubuntu@10.16.3.63, ssh exits with:
Failed to establish SSH connection: "exit status 5"
I have installed askpass and the following log is generated:
2017/02/06 09:05:15 [ERROR]: ssh_helper: missing config 'vault_addr'

@frezbo This is strange. Silly, but I would cross check if the config file containing the values and the config file actually being used by the helper are the same or not.
