Waterlock LDAP Auth

waterlock-ldap-auth is a module for waterlock providing a LDAP authentication method for users based on customizeable LDAP queries. It uses ldapauth-fork to faciliate LDAP authentication.

Usage

npm install waterlock-ldap-auth

set the following option in your waterlock.js config file

authMethod:[
  {
    name: "waterlock-ldap-auth",
    connection: {
      url: "ldaps://ldap.example.com:636",
      bindDn: "uid=myadminusername,ou=users,o=example.com",
      bindCredentials: "mypassword",
      searchBase: "ou=users,o=example.com",
      searchFilter: "(uid={{username}})",
      cache: true
    },
    attributes: {}
  }
]

Auth Model

LDAP auth adds the following attributes onto the Auth model:

  entryUUID: {
    type: 'string',
    unique: true
  },
  dn: {
    type: 'string',
    unique: true
  }

They map the dn and theentryUUID values of the LDAP user to the Auth model.

With the way waterlock is designed and this model you can override any of these attributes.

waterlock-ldap-auth will create a new Auth and User if LDAP authentication succeeds but no Auth/User is found.

Mapping LDAP attributes

It is possible to map attributes from the LDAP user object to the Auth model automatically. Just add objects to the attributes property:

authMethod:[
  {
    name: "waterlock-ldap-auth",
    connection: { ... },
    attributes: {
      uid: {
        uid: {
          type: 'string'
        }
      },
      cn: {
        fullname: {
          type: 'string'
        }
      },
      mail: {
        email: {
          type: 'string'
        }
      }
    }
  }
]

This example adds a mapping from LDAP to Auth model:

LDAP	Auth model	Type
uid	uid	string
cn	fullname	string
mail	email	string
