Understanding External Authentication
Even if it's not a super interesting topic, and really only applies if you're managing a FileMaker server, it always pays to know how things work behind the scenes. If you've never used FileMaker's external authentication via LDAP then you'll want to watch this particular video.
If you're creating any type of FileMaker solution which needs to know when your users both enter and exit the system, which especially applies to using external authentication, then you'll enjoy the super simple access log discussed within the video.
There's even a great tip about adding a unique backdoor for emergency access to your files - should you forget your master password for Full Access. Remember, this may seem like a boring topic but it's critical information to have if you're going to be managing any type of complex solution with centralized access controls.
