+Authenticate a user against an LDAP directory
+===
+
+Useful for Windows Active Directory and other LDAP-based organisations
+to maintain a single password across the organisation.
+Optionally authenticates only if a member of a given group in the directory.
+
+By default, the person must have registered with Friendica using the normal registration
+procedures in order to have a Friendica user record, contact, and profile.
+However, it's possible with an option to automate the creation of a Friendica basic account.
+
+Note when using with Windows Active Directory: you may need to set TLS_CACERT in your site
+ldap.conf file to the signing cert for your LDAP server.
+
+The configuration options for this module may be set in the `config/addon.config.php` file
+e.g.:
+
+	'ldapauth' => [
+        // ldap hostname server - required
