Explore LDAP Integration with Calliope.

We want to scrub out CalliopeAuth, and instead use Cyverse's LDAP authentication system.

My Open-Distro can now query Cyverse's LDAP server for the current user. I would hope it's a short leap from this to using it to check if a user has permissions to perform an action. (This will likely require filling in the authz field in securityconfig.yml).

There seems to be some indication that open-distro/LDAP may still be running in some sort of demo mode. Can we confirm this is not the case, or fix it to run normally? Need to ask Jackson about this one. I have no clue how the backend works here.
