This document describes the support for authenticating users using SSH certificates and the authorized principals command in EOS. SSH certificate authentication was previously restricted to just using the authorized principals file. This file is populated by configuring authorized principals for each user. In order to login with a SSH certificate a user must present a certificate that includes at least one of their configured principals. The authorized principals command allows this list of configured principals to be generated by an executable dynamically at runtime. This provides a more flexible and scalable way to perform SSH certificate authentication.
