Re: OpenLDAP uses crypt() of OpenSSL instead of system libraries (ITS#2123)

I know I'm going to annoy some people by saying this, I apologize in 
advance.  But this is definately an OpenLDAP bug.

It is entirely reseanable for two libraries to export the same function 
name.  It is up to OpenLDAP's build environment to make sure it gets the 
function it expects.  Maybe by specifying the library link order.

There should be an easier way to do this that to patch OpenSSL.

How about the solution he suggested? ie. -lcrypt before -lcrypto in the 

We could also specify -lc before -lcrypto for platforms without a 
libcrypt maybe.
