Website + LDAP + TeamPass, how to configure?

Website + LDAP + TeamPass, how to configure?

Got a small issue using my web server where I host a TeamPass website
(http://www.teampass.net).
I am using Ubuntu 13.04 Server and installed LAMP and I have a Windows
2008 R2 with Active Directory running. I can't get the ldap authentication
working. I am sure I have missed something but can really figure it out...
My Ubuntu server is not joined in the domain, and I guess I have to set
some log in credentials to connect to my W2K8-server/AD... but where? I
can't find anywhere in the TeamPass settings to add the login details.
Need some help here.
