AWS Transfer Family Terraform module now supports Okta and Microsoft Entra ID integration examples

[AWS Transfer Family Terraform module](https://github.com/aws-ia/terraform-aws-transfer-family) now includes end-to-end examples for deploying Transfer Family endpoints integrated with Okta and Microsoft Entra ID as custom identity providers (IdP) for authentication and access control. This allows enterprises already using these platforms to automate and streamline the deployment of Transfer Family servers with their existing identity infrastructure. The Terraform module and examples are based on the open source [Custom IdP solution](https://github.com/aws-samples/toolkit-for-aws-transfer-family/tree/main/solutions/custom-idp), which provides standardized integration with widely used identity providers and includes built-in security controls such as multi-factor authentication, audit logging, and per-user IP allowlisting. The Okta example supports password-based authentication flows, time-based one-time password (TOTP)-based MFA, and attribute retrieval, while the Entra ID example demonstrates password-based authentication for organizations standardized on Microsoft's identity platform. Customers can get started by using the new module from the [Terraform Registry](https://registry.terraform.io/modules/aws-ia/transfer-family/aws/latest).
