/**
* wpDirAuth: WordPress Directory Authentication (LDAP/LDAPS).
*
* Works with most LDAP enabled directory services, such as OpenLDAP,
* Apache Directory, Microsoft Active Directory, Novell eDirectory,
* Sun Java System Directory Server, etc.
*
* Please note that wpDirAuth will start in safe mode if it detects that
* another plugin is in conflict, by detecting if the wp_authenticate and
* wp_setcookie functions have already been overwritten. It cannot,
* on the other hand, detect plugins that might want to overwrite these
* functions after wpDirAuth has been loaded.

<blockquote>
LDAP support in PHP is not enabled by default. You will need to use the

support. DIR is the LDAP base install directory. To enable SASL support,
be sure --with-ldap-sasl[=DIR] is used, and that sasl.h exists on the system.

wpDirAuth cannot provide directory authentication without having access to this function.

Please disable any WP plugins that deal with authentication in order to use wpDirAuth, or upgrade your instance
of WordPress to one that supports Hooks. Unfortunately, we cannot provide you with more info as to which plugin is in conflict.
