I've just installed a shiny new server into a shiny new Tree and added
users. I enabled iFolder (as I've done quite a few times before, but now
when a user tries to login, they get Error 23 or error 25 and the server
console is giving Login authentication failure (ldap time=3secs) or Login
Encryption Mismatch.

Workstations are XP with SP2 fully patched
