protected function SamlService::getSamlAuth in SAML Authentication 4.x

Same name and namespace in other branches

1. 8.3 src/SamlService.php \Drupal\samlauth\SamlService::getSamlAuth()
2. 8.2 src/SamlService.php \Drupal\samlauth\SamlService::getSamlAuth()

Returns an initialized Auth class from the SAML Toolkit.

Parameters

string $purpose: (Optional) purpose for the config: 'metadata' / 'login' / 'acs' / 'logout' / 'sls-request' / 'sls-response'. Empty string means 'any', but likely shouldn't be used anywhere. (The way many callers hardcode this argument may seem strange, until you realize that _these callers_ only have one possible purpose too, in practice. This is almost sure to be refactored away in a future version.)
