require 'simple_ldap_authenticator' plugin :rodauth do enable :login, :logout # Don't require the bcrypt library, since using LDAP for auth require_bcrypt? false # Treat the login itself as the account account_from_login{|l| l.to_s} # Use the login provided as the session value account_session_value{account} # Store session value in :login key, since the :account_id # default wouldn't make sense session_key :login password_match? do |password| SimpleLdapAuthenticator.valid?(account, password) end end

How to start use Rodauth?

Slide 83

• Resolve database dependencies • Define Rodauth features

Slide 84

Slide 84 text

Database dependencies

Slide 85

Slide 85 text

• Setup database • Create tables

Slide 86

Slide 86 text

Setup With Postgresql # Load extentions psql -U postgres -c "CREATE EXTENSION citext" ${DATABASE_NAME} # Create database accounts createuser -U postgres ${DATABASE_NAME} createuser -U postgres ${DATABASE_NAME}_password

Slide 87

Slide 87 text

Setup With Postgresql create_table(:accounts) do primary_key :id, :type=>:Bignum foreign_key :status_id, :account_statuses, :null=>false, :default=>1 if db.database_type == :postgres citext :email, :null=>false constraint :valid_email, :email=>/^[^,;@ \r\n]+@[^,@; \r\n]+\.[^,@; \r\n]+$/ index :email, :unique=>true, :where=>{:status_id=>[1, 2]} else String :email, :null=>false index :email, :unique=>true end end case database_type when :postgres user = get{Sequel.lit('current_user')} + '_password' run "GRANT REFERENCES ON accounts TO #{user}" end

Slide 88

Slide 88 text

Define Rodauth Features plugin :rodauth, :json=>true, :csrf=>false, :flash=>false do enable :change_password, :close_account, :create_account, :login, :logout, :remember, :reset_password, :verify_account, :otp, :recovery_codes, :sms_codes, :password_complexity, :disallow_password_reuse, :password_grace_period, :account_expiration, :single_session, :jwt, :session_expiration, max_invalid_logins 2 allow_password_change_after 60 verify_account_grace_period 300 jwt_secret secret sms_send do |phone_number, message| MUTEX.synchronize{SMS[session_value] = "..."} end end
