Re: Migrate MD5 passwords to OpenLdap 2.0.x with MigrationTools

Super, it's work.

But, why this problem stay since 1999? Why isn't include in the officials releases?

I'm relatively sure that this is part of the same issue I struggled with a while back.  Someone pointed me at an old post (from 1999) which contained the fix. 
http://www.openldap.org/lists/openldap-software/200103/msg00125.html   It involves changing the order of the included libs when you compile openldap.

Here's a paste of the content of that post:

I can see why you'd think that.  It looks like OpenSSL 0.9.6 supports MD5
passwords now to; I see in the change log:

  *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').

Anyhow, I made this simple patch that moves $(LUTIL_LIBS) ahead of
$(SECURITY_LIBS), in case anyone else is searching the archives for a
solution to the same problem.
