ppolicy "check_password" needs include files not available in install

[Chris Shenton <Chris.Shenton@nasa.gov>]

I'm finding the ppolicy overlay very useful for implementing our  
enterprise's password policies.  The build process is a bit of a  
nuisance tho.

I'm using a modified version of Michael Steinmann's check_password,  
based on:

http://open.calivia.com/projects/openldap/browser/check_password/ 
check_password.c?rev=5

It needs:

#include <portable.h>
#include <slap.h>

in order to reference structures like:

char *pPasswd, char **ppErrStr, Entry *pEntry)
{
    char       *szErrStr = (char *) ber_memalloc(128);
...

But those includes, and the files they include in turn, do not exist  
in the installed LDAP include files.  So in order to build this  
little check_password.c program I have to untar and then ./configure  
all the OpenLDAP source again.

I realize that check_password.c is not an official part of OpenLDAP  
but would it be possible to put the include files that overlays like  
this need into the installed locations so overlays wouldn't need to  
get and config OpenLDAP all over again?

Or can you suggest other ways to get at the structure information  
that 3rd party software like this needs to compile?

Thanks.
