Dear LazyFedi, I'm looking for a #SaaS solution that acts as a kind of #SSO multiplexer.

I have 4 Microsoft tenancies, and I can map users to tenancies by email address. What I want is something that acts as a single frontend to all of them for #SAML / #OpenID logins.

I need this to set up SSO for some of our other SaaS products which only support one provider.

(NB: this needs to be SaaS, UK/EU based. I'm not able to self host anything in this context)

#Authentication #AuthN

@diffrentcolours I'm not 100% sure if I'm reading what you're trying to do correctly, but I'm pretty sure you should be able to do that with Keycloak? It's OSS so you can try it locally to make sure it does what you need, and if so there are several managed hosting services for it available

e.g. (note, not an endorsement, I've only used it self hosted, but they don't look immediately sketchy. There are a fair number of them if you search) https://elest.io/open-source/keycloak or https://www.peaknetworks.com/server-cloud/hosting/keycloak
