Just the same way as described in

In 21.4 it is exactly the same, since that 21.5 change was copied into
21.4 (stable) branch without any correction, as pointed out in

As for platforms, one requiring `-lldap -llber' was asplinux 7.1 on
i386, with openldap bundled with it.  In other linux-gnu systems
linking with `-lldap' only may succeed, including mandrakelinux 10.0
on i386.  Never tried to figure out, whether that depends on dynamic
linker features, or openldap version, or both (newer openldap making
use of newer dynamic linker features).  Anyway, can not expect linking
with `-lldap' only to succeed on all systems.

Anyway, can easily reproduce the failure by writing a script that is
used in place of compiler and always fails if `-lldap' without
`-llber' is passed to it.  Actually used such a script to debug.  Will
post it on request.


Would like to see `config.log' entries on ldap configuation on
Volker's system, whatever it is.  What value would old / 21.4.17
`configure' code assign to `LIBS' on that system?
