Sacha Al Himdani bcd05a2e55 Reject empty SAML NameIDs on login
Empty NameID values were stored as '' and occupied the
unique saml_subject index, causing duplicate-key failures
on later logins. Reject blank NameIDs during assertion
validation, return a clear error when a NameID is already
linked to another account, and stop returning internal
errors from the SAML consume endpoint.
