LDAP+TLS configuration problems

Hello, I am trying to use PHP's LDAP module with TLS. I have no problems using the normal LDAP functions, however I am never able to use ldap_start_tls(). Everytime I do so I get the following error: "Warning: LDAP: Unable to start TLS: Not Supported in <php page here> on line n" I have verified that PHP is linked against the proper ldap libraries. (These libraries have been compiled with TLS support as I have other LDAP utilities that use TLS without problem) morpork:/usr/local/apache/libexec# ldd libphp4.so | grep ldap libldap.so.2 => /usr/local/ldap/lib/libldap.so.2 (0x4015c000) liblber.so.2 => /usr/local/ldap/lib/liblber.so.2 (0x401ba000) I have also verified that both LDAP servers I have tried connecting to are TLS enabled. I've looked at the PHP source that makes the ldap_start_tls_s connection and noted that it wasn't much different from other applications that use it. Which leaves me fairly confused. Anyone have a similar problem, thoughts, suggestions, ideas? -matt -- Matthew Wirges Developer, CERIAS Incident Response Database wirges@cerias.purdue.edu
