CHW-1107 SSODomainNotAllowed

your email domain is not allowed for this organization

Default message: your email domain is not allowed for this organization
HTTP status: 403 (client)

Problem. The IdP returned a verified email whose domain is not on the org’s allowed_domains allow-list. Cause. Users from this domain are not permitted to sign in via this org’s SSO configuration, even though the IdP accepted them. Fix. Ask an org admin to add the domain to allowed_domains, or use an account with an allowed domain. HTTP 403.
