Errbit LDAP Authentication not working - ruby-on-rails

Question

I'm trying to install errbit to track bugs more easily.
I followed the Installation Instructions from:
https://github.com/errbit/errbit
and
Installed the LDAP Authentication gem:
Gemfile:
gem "devise_ldap_authenticatable", :git => "git://github.com/cschiewek/devise_ldap_authenticatable.git"
executed:
rails generate devise_ldap_authenticatable:install
So far everything went good. The Unicorn Application Server starts without any issues.
But If I login I get this message:
Problem:
Validation of User failed.
Summary:
The following errors were found: Email can't be blank, Name can't be blank
Resolution:
Try persisting the document with valid data or remove the validations.

What did I do wrong?
Update:
It works now so far.
But I'm still gitting one more Issue:
Mongoid::Errors::Validations (
Problem:
Validation of User failed.
Summary:
The following errors were found: Name can't be blank
Resolution:
Try persisting the document with valid data or remove the validations.):
app/controllers/application_controller.rb:48:in `set_time_zone'
I tried to remove the LDAP Validation, but that also didn't work.

Answer 1

sorry if this answer comes too late. Here's what I did to get a working LDAP setup.
In app/models/users.rb I added the following method:
def ldap_before_save
name = Devise::LDAP::Adapter.get_ldap_param(self.username, "givenName")
surname = Devise::LDAP::Adapter.get_ldap_param(self.username, "sn")
mail = Devise::LDAP::Adapter.get_ldap_param(self.username, "mail")
self.name = (name + surname).join ' '
self.email = mail.first
end
In config/initializers/devise.rb, set the following params
config.ldap_create_user = true
config.ldap_use_admin_to_bind = true
Create a new file config/initializers/devise_ldap.rb with the following contents:
Errbit::Config.devise_modules << :ldap_authenticatable
