- # If the source user doesn't exist, we do our best. AgenDAV has a
- # "shares" table that isn't keyed on the username, but rather the
- # principal URL. And its "prefs" table doesn't contain entries for
- # users who have default preferences. As a result, we may need to
- # perform some find/replaces in the "shares" table even if no
- # corresponding user exists in the "prefs" table (which is how we
- # tell if a user exists in AgenDAV). Thus it's not a fatal error if
- # the *src* user doesn't exist.
