OpenVPN & LDAP

Hi,

I´m quite new to RouterOS. I am looking to implement it as OpenVPN Server (amongst other things).
So my question is: does Routerboard´s OpenVPN server integration support LDAP ?
and if not, is it possible to install/use the LDAP plugin for OpenVPN ( https://code.google.com/p/openvpn-auth-ldap/ ) ?

Thanks in advance !

Broter.
