(DOCSP-38815): Added section for authentication considerations. (#227)

@Vodyanoy17 and @JuliaMongo, I added a section for authentication
considerations to the following page and added Kerberos as not
compatible. There was a preexisting note about Kerberos and the
automation agent. Not sure whether we can remove it.
