Description:
------------
For whatever reason, the php4 and php5 from FreeBSD ports refuses to properly configure SSL/TLS    
support for the LDAP module.                                                                       
                                                                                                   
This breaks the TLS/SSL functionality in net/phpldapadmin and sysutils/ldap-account-manager        
(CC'ing maintainers)                                                                               
                                                                                                   
I've got two current i386/RELENG_5_3 boxes.  Both with Apache apache-2.0.54_2 and                  
openldap-client-2.2.27.                                                                            
                                                                                                   
The ldap client binaries are linked to SSL fine and can talk both ldaps:// and Start_TLS over      
ldap://.  That's out of the question.                                                              
                                                                                                   
One with php4-4.4.0, one with php5-5.0.3_2 (see below).  Both have the LDAP and SSL php            
extension modules installed:                                                                       
                                                                                                   
$ egrep -i "ldap|ssl" /usr/local/etc/php/extensions.ini

The php5 box is as well:                                                                           
                                                                                                   
$ ldd /usr/local/lib/php/20041030/ldap.so

The problem is that ldap_start_tls() is an unregistered/invalid function.  When i run the functions.php at http://www.sitepoint.com/article/php-command-line-2                
                                                                                                   
ldap_start_tls() isn't listed on either machine (see below).

Reproduce code:

I traced it down:                                                                            
                                                                                                   
in /usr/ports/net/php5-ldap/work/php-5.0.4/ext/ldap/configure ->                                   
conftest -> ldap_start_tls_s();                                                                    
ldap_start_tls_s return false -> ac_cv_func_ldap_start_tls_s=no in config.log                      
config.log -> ldap.h -> #undef HAVE_LDAP_START_TLS_S

...therefore ldap_start_tls isn't registered.  The question is why the conftest.c in GNU           
autoconf is failing with:

Actual result:

I don't dable in GNU Autoconf, and I recommend everyine else do the same, but if someone actually wants to fix the autoconf ascpet of this so that a Patch on the Free/NetBSD side isn't required forever, then god speed.  

My temporary solution is:

1) cd /usr/{ports,pkgsrc}/{net/php5-ldap,databases/php-ldap} on {Free,Net}BSD respectively         
                                                                                                   
2) sudo make configure                                                                             
                                                                                                   
3) sudo vim                                                                                        
On FreeBSD

on NetBSD:
