I'm averse to fiddling with init script priorities in this manner.  There's
no good way to handle changes to these priorities on upgrade, and I think
that the use case of needing to connect to a local slapd server for your NSS
backend, that early in the boot sequence, is a marginal one.  I really don't
think anything starting at sequence 20 should need non-system users; I think
if anything, it would be more correct for exim to start later.

I also think this is entirely an exercise in futility and that we should be
migrating to dependency-based runlevels - and that users who really need
slapd running for local user lookups should in the meantime adjust by hand
if necessary, because this really isn't a well-supported configuration. 
(e.g., winbind is another name service daemon that runs locally which is
started at S20.)

So let's please work instead on getting proper dependency-based rules in
place, so that nss-ldap declares a Should-Start: slapd, and nss-ldap,
winbind, and nscd can all Provide some sort of "user_lookups" virtual
service that the init scripts for exim & co. can declare a dependency on.
