I'd hope you'd see these problems almost entirely go away in future with a
switch to sssd rather than nss_ldap, as it makes the whole process a lot more
stateful and aware of what's going on.

Having an rc.local that does an nsswitch.conf twiddle is probably a viciously
robust way of dealing with this problem...
