Bug Fix Bulletin — v56.0.0
SAML and HUB login case-insensitivity; all remaining platform bug fixes for the January 2026 release
This bulletin documents the SAML and HUB login case-insensitivity improvements shipped in Tiled v56.0.0. Note: the full case-insensitive email handling for API and Hub was shipped in v57.0.0 (KB-v57-03). The v56.0.0 items represent the initial implementation groundwork for SAML case handling that was completed and expanded in v57.0.0.
|
Note: The SAML/HUB email case-insensitivity work spans v56.0.0 and v57.0.0. v56.0.0 delivers the initial SAML lookup resilience changes; v57.0.0 (KB-v57-03) completes the implementation with API and Hub login normalization. For the full authentication improvement picture, read this bulletin alongside KB-v57-03. |
2. SAML / HUB Login Case-Insensitivity — v56.0.0 Component
The following authentication improvements were shipped in v56.0.0 as part of the case-insensitive login initiative:
|
Ticket |
Area |
Resolution |
|
SAML Lookup |
SAML — Case-Insensitive Assertion Lookup (initial) |
SAML user lookup was updated to perform case-insensitive matching on the email attribute asserted by the identity provider. This resolves authentication failures for enterprise SSO users whose IdP asserts an email address in a different case than the value stored in Tiled. This initial implementation addresses the most common SAML case mismatch scenarios; edge cases were addressed in v57.0.0. |
|
HUB Login |
Hub — Email Case Handling (initial) |
Initial handling for case variations in Hub login email entry. Users entering their registered email in a different case than originally registered now authenticate successfully in the majority of cases. The full normalization (converting all input to lowercase before lookup) was completed in v57.0.0 (TD-6406). |
3. QA Validation — Authentication Scenarios
|
QA Scope: SAML/HUB login case scenarios were included in the v56.0.0 QA scope. Both the SAML lookup and Hub login case scenarios were validated against known case-mismatch configurations. |
|
SAML — IdP uppercase email |
Verified: SAML assertion with uppercase email resolves to Tiled user record. |
|
HUB — Mixed-case login |
Verified: Hub login with mixed-case email authenticates successfully for the majority of test cases. |
|
SAML — Edge cases |
Deferred: remaining edge cases tracked to v57.0.0 for completion. |
4. Audit Evidence
• The SAML lookup case-insensitivity fix constitutes SOC 2 CC6.1 (Logical and Physical Access Controls) evidence — the authentication layer now correctly resolves SAML-asserted user identity regardless of email case variation. This closes a class of authentication failures that could deny access to legitimate, authorized users.
