[Samba] fix for libldap configure error when using openldap on FreeBSD

[Adam Laurie]

i have seen several reports of the following problem:

   ./configure --with-ldap --with-krb5=/usr/heimdal --with-ads 
--config-cache --with-pam
   [snip]
   checking for LDAP support... yes
   checking ldap.h usability... yes
   checking ldap.h presence... yes
   checking for ldap.h... yes
   checking lber.h usability... yes
   checking lber.h presence... yes
   checking for lber.h... yes
   checking for ber_scanf in -llber... yes
   checking for ldap_init in -lldap... no
   checking for ldap_domain2hostlist... no
   checking for ldap_set_rebind_proc... no
   checking whether ldap_set_rebind_proc takes 3 arguments... 3
   checking for ldap_initialize... no
   configure: error: libldap is needed for LDAP support

despite libldap being present and correct. in my case (FreeBSD 5.2.1), 
this turned out to be a crypto library problem as well as the more 
obvious path issues, and the fix is:

   CFLAGS=-I/usr/local/include CPPFLAGS=-I/usr/local/include 
LDFLAGS="-lcrypto -L/usr/local/lib" ./configure --with-ldap 
--with-krb5=/usr/heimdal --with-ads --config-cache --with-pam

hope this is useful to someone somewhere... :)

please note that i'm not subbed to this list, so copy me in on any 
replies if you want me to see them.

cheers,
Adam
