Validate the 'token/ticket' header for SSO Authentication

[TheEYL]

From what I can see in the code examples, this library can produce the token or tickets:

      service_fqdn: 'm01.krb.local'
    }, function (err, token) {
      if (err) {
        console.log(err)
      } else {
        console.log('SPNEGO token :', token)
      } }) 

I would like to validate the 'token/ticket'. Not sure if this library supports that. Is it the case?

I don't remember that we have a validation function.
