Support for GitLab 10

[makeaweli]

In case anyone needs this, I've modified the script to run on GitLab 10. Such as lifesaver, thanks!:

namespace :gitlab do
  namespace :jd do
    desc 'GitLab | jd | update LDAP users DN (use UPDATE_DN="yes" to actualy do it)'
    task update_ldap_dn: :environment do

			update_dn = ENV['UPDATE_DN']
			adapter = Gitlab::LDAP::Adapter.new("ldapmain")
			
			User.find_each do |user|
				if user.ldap_user? && user.active?
				  print "User (#{user.username} / #{user.email}): "
			                 # change the first argument to whatever your email attribute is named in your AD/LDAP server
					ad_identity = adapter.user("mail", user.email)
			
					unless ad_identity.nil?
						unless (ad_identity.dn == user.ldap_identity.extern_uid)
			        user.ldap_identity.extern_uid = ad_identity.dn
			        puts "[WARNING]".color(:yellow)
			        puts user.ldap_identity.extern_uid_change
			
			        if update_dn == 'yes'
			          user.ldap_identity.save!
			          puts "[Updated]".color(:green)
			        end
			      else
			        puts "[OK]".color(:green)
						end
					end
				end
			end
		end
	end
end
