Environment
TCA: 3.4.0.1
TCP: 5.1
Cause
A new tca-auth module was introduced in VMware Telco Cloud Automation (TCA) 3.4 as part of a significant architectural transition to support OIDC and modern authentication frameworks. This update also included several third-party library upgrades intended to address and remediate known security vulnerabilities.
Following these changes, an issue was identified where the tca-auth service fails to process login requests if the TCA UI transmits a large user context (typically due to extensive group memberships).
Resolution
Resolved in TCA 3.4.0.1
