connector/saml: make unparsable (trailing, non-space/newline) data an error

Fixes #1304, if we want to be harsh.

However, I think if it was the user's intention to pass two certs, and
the second one couldn't be read, that shouldn't just disappear. After
all, when attempting to login later, that might fail because the
expected IdP cert data isn't there.

connectors/ldap: treat 'constraint violation' on bind as bad credentials

Some directory servers (I think it's Oracle) return

    Constraint Violation: Exceed password retry limit. Account locked.

when attempting to login too many times. While constraint violation can
mean many things, we're checking this as an error on BIND, so it's
more likely that something like this has happened than any other thing.

Hence, we should treat it as an "incorrect password" situation, not an
internal error.

It would of course be preferrable to surface more information about this
precise error (and similar ones), but I think this is beyond this small
change.
