Communication Strategy for mfa-simple

[Jérôme Rautureau]

Hello guys,

We have two instances of CAS 7.3.5 (docker image)

I don't know how to specify that the cas mfa-simple MUST use email only.

tried various config such as : 

cas.authn.mfa.simple.communication-strategy.supported-types=EMAIL

i didn't find any documentation about this configuration too.

I want ot keep SMS notification for other usages (pw reset for instance)

Thanks in advance

Hi Jérôme,

I think your observations are correct, i.e. there is currently no way how to disable SMS just for Simple MFA via CAS configuration.

The only option here seems to override the mfaSimpleMultifactorTokenCommunicationStrategy bean (as per this CAS guide) with an instance that would return something else than the default ALL = EnumSet.allOf(TokenSharingStrategyOptions.class);. For reference, the OOTB bean is defined as follows:

        @ConditionalOnMissingBean(name = CasSimpleMultifactorTokenCommunicationStrategy.BEAN_NAME)
        @Bean
        @RefreshScope(proxyMode = ScopedProxyMode.DEFAULT)
        public CasSimpleMultifactorTokenCommunicationStrategy mfaSimpleMultifactorTokenCommunicationStrategy() {
            return CasSimpleMultifactorTokenCommunicationStrategy.all();
        }

If you need even more control over the sending process, you can override the whole CasSimpleMultifactorSendTokenAction class - but it would be probably an overkill in this case.

Best regards

Petr

ok. I will do that.

Thanks Petr for your help
