That was exactly the way we ran it, per that documentation, but it didn't appear to do anything.

You can check the /var/log/dirsrv/slapd-INST/errors log file to see if it ran and if there were any errors.

So, I figured out that just adding/removing users from groups would trigger it to update ALL groups for that user,

Yes, it does.

so I just bulk added everyone to a group and problem solved.

Existing entries are not added automatically when enabling the plugin, you have to either run the fixup-memberof.pl script (if it works for you - it never did anything for us),

This is the documented way to do it.

6.1.4.5. Synchronizing memberOf Values
The MemberOf Plug-in automatically manages the memberOf attribute on group member entries, based on the configuration in the group entry itself. However, the memberOf attribute can be edited on a user entry directly (which is improper) or new entries can be imported or replicated over to the server that have a memberOf attribute already set. These situations create inconsistencies between the memberOf configuration managed by the server plug-in and the actual memberships defined for an entry.
Directory Server has a memberOf repair task which manually runs the plug-in to make sure the appropriate memberOf attributes are set on entries. There are three ways to trigger this task:

    In the Directory Server Console
    Using the fixup-memberof.pl script
    Running a cn=memberof task,cn=tasks,cn=config tasks entry

6.1.4.5.1. Initializing and Regenerating memberOf Attributes Using fixup-memberof.pl
The fixup-memberof.pl script launches a special task to regenerate all of the memberOf attributes on user entries based on the defined member attributes in the group entries. This is a clean-up task which synchronizes the membership defined in group entries and the corresponding user entries and overwrites any accidental or improper edits on the user entries.

    Open the tool directory for the Directory Server instance, /usr/lib/dirsrv/slapd-instance_name/.
    Run the script, binding as the Directory Manager.

    ./fixup-memberof.pl -D "cn=Directory Manager" -w password

The fixup-memberof.pl command is described in more detail in the Configuration and Command-Line Tool Reference.

If it is not working for you, then please describe the steps you took.

or you have to make a change to each pre-existing user to trigger the memberOf updating. The easiest way to do that is to simply create a group and add everyone to it, then remove it (unless of course you actually have a use for said group). If you already have a group with everyone in it, you can probably create a new group, and add that group as a member of the new group.

I'm not sure if existing entries are added automatically when you enable the plugin.
I would assume so, but in any case at any time you can run the fix-up task that will sync the attributes.
You can define the scope for the task using a filter, for example, fix only ou=orgunit,ou=People,... branch of the DIT.
