I use something similar. Basically, for looking up e-mail contacts,
I use The little Brother's Database lbdb¹ together with mutt and Vim.
Additionally Vim Script 1757² plus a custom complete script that I
found online somewhere, but don't find it anymore (so I attach it
here)

The lbdb comes with a little script lbdbq that can query different
sources, e.g. mutt alias file, abook file, OS X adressbook, ldap
server, etc. to query for contacts so in theory it should be able to
query your own ldap server, but if that does not work
for you, it should at least give you an starter how to write your own
script.
