It's 2018 and Aruba still only lets you enter one single IP address for a RADIUS or LDAP server. Why is my question.
This is bad because it is very limiting. Businesses and corporations need to ensure there is redundancy. Using round-robin DNS is a very old form of redundancy and used quite a lot when it comes to authentication. Can't use it in Aruba though. You can only enter one single IP address for an authentication server.
