It is passed a qualified + ``@localpart:domain`` user id, and the password provided by the user. + + The method should return a Twisted ``Deferred`` object, which resolves to + ``True`` if authentication is successful, and ``False`` if not. diff --git a/synapse/config/password_auth_providers.py b/synapse/config/password_auth_providers.py index 90824cab7f..e9828fac17 100644 --- a/synapse/config/password_auth_providers.py +++ b/synapse/config/password_auth_providers.py @@ -13,41 +13,40 @@ # See the License for the specific language governing permissions and # limitations under the License. -from ._base import Config, ConfigError +from ._base import Config from synapse.util.module_loader import load_module +LDAP_PROVIDER = 'ldap_auth_provider.LdapAuthProvider' + class PasswordAuthProviderConfig(Config): def read_config(self, config): self.password_providers = [] - - provider_config = None + providers = [] # We want to be backwards compatible with the old `ldap_config` # param. ldap_config = config.get("ldap_config", {}) - self.ldap_enabled = ldap_config.get("enabled", False) - if self.ldap_enabled: - from ldap_auth_provider import LdapAuthProvider - parsed_config = LdapAuthProvider.parse_config(ldap_config) - self.password_providers.append((LdapAuthProvider, parsed_config)) + if ldap_config.get("enabled", False): + providers.append[{ + 'module': LDAP_PROVIDER, + 'config': ldap_config, + }] - providers = config.get("password_providers", []) + providers.extend(config.get("password_providers", [])) for provider in providers: + mod_name = provider['module'] + # This is for backwards compat when the ldap auth provider resided # in this package. - if provider['module'] == "synapse.util.ldap_auth_provider.LdapAuthProvider": - from ldap_auth_provider import LdapAuthProvider - provider_class = LdapAuthProvider - try: - provider_config = provider_class.parse_config(provider["config"]) - except Exception as e: - raise ConfigError( - "Failed to parse config for %r: %r" % (provider['module'], e) - ) - else: - (provider_class, provider_config) = load_module(provider) + if mod_name == "synapse.util.ldap_auth_provider.LdapAuthProvider": + mod_name = LDAP_PROVIDER + + (provider_class, provider_config) = load_module({ + "module": mod_name, + "config": provider['config'], + }) self.password_providers.append((provider_class, provider_config)) |
