Worked on the opentofu/terraform-provider-azuread repository to address a targeted issue in redirect URI validation for Azure AD Terraform provider configurations. Focused on Go development and Terraform provider internals, the work involved updating the IsRedirectUriFunc logic to recognize brk-multihub as a valid redirect URI scheme. This change prevented valid brk-multihub-based URLs from being incorrectly rejected, thereby improving the reliability of multi-hub automation workflows. The update was isolated to the URI validation component, minimizing risk to other features. By refining URI validation, the work reduced deployment friction and enabled smoother CI/CD automation for users relying on complex Azure AD setups.
