I have added:
  Should-Start: slapd
to fix the problem that nslcd should be started after slapd.

However to solve the problem that nslcd should be started before mail
servers I would like to add:
  Provides: $named
at least exim and postfix have a Required-Start for this) but the
description on http://wiki.debian.org/LSBInitScripts suggests that such
a provides should be specified in a different place. Where should that

I have filed bug #478674 for this. The end sequence is already very high
(80) so I don't think there is a reason to make this even higher. The
dependencies of slapd are either started at runlevel S ($remote_fs and
$network) or at sequence 10 ($syslog).

This would however change local customisations that administrators may
have made to their init script order. Something like this could do it
though in postinst:

[ -l /etc/rc2.d/S20nslcd ] &&
mv /etc/rc2.d/S20nslcd /etc/rc2.d/S19nslcd
[ -l /etc/rc3.d/S20nslcd ] &&
mv /etc/rc3.d/S20nslcd /etc/rc3.d/S19nslcd
[ -l /etc/rc4.d/S20nslcd ] &&
mv /etc/rc4.d/S20nslcd /etc/rc4.d/S19nslcd
[ -l /etc/rc5.d/S20nslcd ] &&
mv /etc/rc5.d/S20nslcd /etc/rc5.d/S19nslcd
[ -l /etc/rc0.d/K20nslcd ] &&
mv /etc/rc0.d/K20nslcd /etc/rc0.d/K21nslcd
[ -l /etc/rc1.d/K20nslcd ] &&
mv /etc/rc1.d/K20nslcd /etc/rc1.d/K21nslcd
[ -l /etc/rc6.d/K20nslcd ] &&
mv /etc/rc6.d/K20nslcd /etc/rc6.d/K21nslcd

However this would work around update-rc.d and be a policy violation:

I suspect not much packages do this when changing sequence number. e.g.
I have an etch system which has been upgraded a lot of times that starts
nscd at sequence 19 but my sid system that has been installed about a
year ago starts it at 20.
