SAML Updates: Duo and Direct Link

[leticiawebb]

Duo Setup

We recently had a customer request SAML setup using Duo as their identity provider. The attribute configuration is slightly different from other identity providers, which caused some issues.

Duo integration with Auth0 utilizes the generic SSO configuration: Configure Single Sign-On. The correct attribute mapping is as follows:

Bridge Attribute	ClickHouse Attribute
Email Address	email

Direct Link

Customers utilizing Azure as an identity provider are able to configure the direct link via the SAML integration. However, Azure will not resolve the URL without an additional / character before the ?connection string.

Correction: https://console.clickhouse.cloud/?connection={organizationId}
