SSO is great in a monoculture environment, but falls down in heterogenous systems. We have Azure SSO, Ping Federate, and a couple of others we're getting rid of

SSO is great in a monoculture environment, but falls down in heterogenous systems. We have Azure SSO, Ping Federate, and a couple of others we're getting rid of. I think it adds unnecessary complexity, and fails too often. Our internal users don't like it because the failure modes are opaque to them compared to a userid/password.
