you using openldap or trying to integrate with an actual MSAD ?
My settings (to connect to MSAD)
URI: ldap://adress.to.my.dc
bind dn: myUserToConnectToDC@domain.com
pass: password.to.user.in.bind.dn
base: dc=domain,dc=com (because i've had set up restrictions on my user, thats why i pointed the full catalogue)
filter: (sAMAccountName={{name}})
try those
