Re: crypto without MD5 (ITS#3039)
You should report this problem to the Debian packagers of
OpenSSL. OpenSSL should be instead without overriding the
system provided crypt(3) function.
As far as OpenLDAP configure, we assume whatever crypt(3) is
provided in the environment is the desired version of crypt(3).
If the environment provides multiple versions, we have no
way to know which one is correct. We're not going to attempt
to guess. (The installer could just as well have wanted the
version in OpenSSL over the version in -lcrypt.)
