getting nginx to work with nginx-auth-ldap

Hi, I'm trying to get our nginx server to talk to our ldap server. i followed what was on: https://github.com/kvspb/nginx-auth-ldap

but i keep getting authorization failed. The credentials i have set up on this are the same as what i have placed somewhere else which works (but it goes to apache)

the syntax for the binddn on the page is:
binddn "TEST\\LDAPUSER";

but i have:

binddn cn=<something here>, ou=<something here>, dc=<somethign here>, and dc=<something here>;

does it need to be in a certain format like "servername\\ldap user name"; ??

i just don't know if there's a trick other than what is described on that github page.
