I'm looking into implementing SSO for customer community. I've been reading the documentation on SSO implementation using either delegated or federated authentication. I have not done SSO before so I'm trying to understand what technical considerations there are between delegated and federated authentication? From what I read so far, federated using SAML is OOB, but delegated authentication has to be requested to be turned on. It also does appear that delegated authentication will work with community licenses. However, are there technical limitations and considerations on which method is used? I don't want to select federated using SAML and then realize I can't use that because of xyz reason.
Any feedback is appreciated.
