[keycloak-user] LDAP User Storage Provider web interface

[Ryan Slominski]

On the admin web interface what do the buttons at the bottom of the LDAP User Storage Provider settings page do?  Specifically the buttons:

Synchronize changed users
Synchronize all users
Remove imported
Unlink users

I don't want Keycloak caching much / anything so I've configured Cache Policy NO_CACHE, Edit Mode READ_ONLY, and Import Users OFF.  It seems like these buttons should not be shown with this configuration as it isn't clear they do anything.  I'm especially mystified by Unlink users button since I can't find any reference on what the heck that does.
