+# Automating SAML Metadata Retrieval in OCI Identity Domains
+
+This solution provisions an **OCI Identity Domain** with Terraform and securely retrieves its **SAML metadata** for integration with external identity providers.
+
+Instead of making the SAML metadata publicly accessible by enabling the *“Configure client access”* option under *Access Signing Certificate*, this approach uses a **temporary confidential OAuth client** to authenticate and download the metadata.
+
+The workflow is:
+
+1. **Provisioning with Terraform (Optional)**
+
+   * Deploy the OCI Identity Domain.
+   * Trigger a shell script via `null_resource` provisioner after domain creation.
+
+2. **Automated Metadata Retrieval via Shell Script**
+
+   * Register a **temporary confidential application** that supports the *client credentials* grant type via OCI CLI.
+   * Request an `access_token` from the Identity Domain OAuth endpoint using the app's credentials.
+   * Call the `/fed/v1/metadata` endpoint with `Authorization: Bearer` header.
+   * Download and save the SAML metadata XML to a local file (`oci_idcs_metadata.xml`).
+   * Deactivate and delete the temporary confidential app (cleanup).
+   * Print the `client_id` and masked `client_secret` to stdout (not stored in Terraform state).
+
+3. **Security Benefits**
+
+   * **No Public Exposure**: The SAML metadata endpoint remains private and is never exposed to the internet.
+   * **Authenticated Access**: Only the temporary, authenticated client can retrieve the metadata.
+   * **Ephemeral Credentials**: The OAuth client is destroyed immediately after use, minimizing the attack surface.
+   * **State-Free Secrets**: The client credentials are never written to the Terraform state file.
+
+This method provides both **automation** and **security**, ensuring SAML metadata can be retrieved programmatically without compromising the confidentiality of signing certificates.
+

+## Resources Created
+
+### By Terraform (Optional):
+1. **OCI Identity Domain** (`oci_identity_domain.identity_domain`) - A managed identity domain in OCI with specified compartment, display name, description, license type, and home region
+2. **Null Resource** (`null_resource.configure_idcs_app`) - Triggers the shell script after domain creation
+3. The **OCI Identity Domain** is not destroyed after creation. The SAML metadate would then be invalid.
+
+### By Shell Script (`create_confidential_app_and_get_saml_meta_data.sh`):
+1. **Confidential OAuth Client App** - Created in the new identity domain with:
+   - Client credentials grant type
+   - Confidential client type
+   - Custom web app template
+2. **SAML Metadata XML File** (`oci_idcs_metadata.xml`) - Downloaded to local filesystem
+3. **Cleanup** - By default, the script deactivates and deletes the confidential app after downloading metadata (unless `KEEP_APP=true`)
+
+## Prerequisites
+
+### Required Tools:
+- **OCI CLI** with Identity Domains commands
+- **jq** (JSON processor)
+- **curl**
+- **python3**
+- **Terraform** ≥ 1.5.0
+
+### Required Configuration:
+1. **OCI CLI configured** with valid profile (default: `DEFAULT`)
+2. **terraform.tfvars** populated with:
+   - `compartment_id` (OCID of the enclosing compartment)
+   - `region`
+   - `domain_display_name`
+   - `domain_description`
+   - `license_type`
+   - `tenancy_ocid`
+   - `oci_profile` 
+
+### Optional (for cleanup):
+- `ADMIN_ACCESS_TOKEN` or
+- `ADMIN_CLIENT_ID` + `ADMIN_CLIENT_SECRET` (for proper app cleanup with admin privileges)
+
+## How to Run
+
+1. **Initialize**: `terraform init`
+2. **Plan**: `terraform plan -out tfplan`
+3. **Apply**: `terraform apply tfplan`
+
+### Environment Variables (optional):
+- `APP_NAME` - Custom app name (default: `saml-metadata-client`)
+- `SCOPE` - OAuth scope (default: `urn:opc:idm:__myscopes__`)
+- `OUT_XML` - Output file path (default: `oci_idcs_metadata.xml`)
+- `KEEP_APP` - Set to `true` to prevent app deletion
+
+The script automatically receives `IDCS_ENDPOINT` and `PROFILE` from Terraform.
+
+## Terraform Flow
+
+During `apply`, the configuration creates the OCI Identity Domain. After the domain exists, Terraform triggers `scripts/create_confidential_app_and_get_saml_meta_data.sh`, which:
+
+- provisions a confidential OAuth client against the new domain via the OCI CLI,
+- regenerates the client secret if necessary,
+- retrieves a client-credentials token, and
+- downloads the SAML metadata document to `oci_idcs_metadata.xml` (override via `OUT_XML`).
+
+The script prints the confidential app ID, client ID, and a masked client secret—store the full secret securely outside of Terraform state.
+
+## Running the Script Standalone
+
+If an identity domain already exists, you can run the script directly without Terraform:
+
+```bash
+IDCS_ENDPOINT="https://idcs-<hash>.identity.oraclecloud.com" \
+PROFILE="oci_profile_name" \
+bash scripts/create_confidential_app_and_get_saml_meta_data.sh
+```
+
+### Optional Environment Variables:
+- `APP_NAME` - Custom app name (default: `saml-metadata-client`)
+- `SCOPE` - OAuth scope (default: `urn:opc:idm:__myscopes__`)
+- `OUT_XML` - Output file path (default: `oci_idcs_metadata.xml`)
+- `KEEP_APP` - Set to `true` to prevent app deletion after metadata retrieval
+- `ADMIN_ACCESS_TOKEN` - Bearer token with Identity Domain Administrator rights (preferred for cleanup)
+- `ADMIN_CLIENT_ID` / `ADMIN_CLIENT_SECRET` - Admin confidential app credentials (alternative for cleanup)
+- `ADMIN_SCOPE` - Admin scope (default: `urn:opc:idm:__myscopes__`)
+
+### Example with custom settings:
+```bash
+IDCS_ENDPOINT="https://idcs-abc123.identity.oraclecloud.com" \
+PROFILE="my-oci-profile" \
+APP_NAME="my-metadata-app" \
+OUT_XML="custom_metadata.xml" \
+KEEP_APP="false" \
+bash scripts/create_confidential_app_and_get_saml_meta_data.sh
+```
+
+This is useful when you need to retrieve SAML metadata from an existing identity domain without provisioning a new one. When you want to keep the confidential application, set the variable KEEP_APP to false.
