SSH postponed authentication (publickey)

An interesting syslog message!

sshd[xxx]: 'Postponed publickey for oracle from ::ffff:130.156.249.64 port 9264 ssh2'

As Tom explains,

ssh is just stepping through the client-configured authentication types (enabled in either ssh_config or ~/.ssh/config) and trying them in turn, but acknowledging that a publickey was presented, and postponing its use until after trying the first auth type.
