Connect
-------

Test the connection to the LDAP server. It creates two
connection, one using the admin credential available 
under `ctx.ldap_admin` and another one with the admin credential
available under `ctx.ldap_config`. Both objects are ldapjs 
client instance.

      return next() if ctx.ldap_admin and ctx.ldap_config
      { root_dn, root_password,
        config_dn, config_password } = ctx.config.openldap_server
      admin = ->
        return config() if ctx.ldap_admin
        ctx.log 'Open admin connection'
        client = ldap.createClient url: "ldap://#{ctx.config.host}/"
        ctx.log 'Bind admin connection'
