A debian/shlibs.local file should override the shlibs declared under
debian/libldap-2.3-0.  That would save folks the trouble of updating the
lintian suppressions for every upload, too. :)  (You can even use the
package version substitution within debian/shlibs.local, as I recall from
one buggy package that managed to export ${Source-Version} in their *public*
shlibs, which then had the variable expansion done at dpkg-shlibdeps
runtime, hee...)
