From ac1118cb12597c1bbaf956ba21fda32fb61fb968 Mon Sep 17 00:00:00 2001 From: "Lee Sudduth (lsudduth)" Date: Tue, 30 Sep 2025 12:04:00 -0400 Subject: [PATCH 1/3] feat: add 1Password CLI integration for secure credential management MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit integrates 1Password CLI to allow users to retrieve credentials from their secure 1Password vault instead of storing them in environment variables or passing them as command-line arguments. ## New Features ### 1Password Helper Module (nac_collector/onepassword_helper.py) - Implements secure credential retrieval via 1Password CLI (`op`) - check_op_cli_available(): Validates 1Password CLI installation - get_op_item(): Retrieves items from 1Password vault with error handling - extract_credentials(): Intelligently parses username, password, and URL from 1Password item fields with case-insensitive matching - get_credentials_from_op(): High-level API for credential retrieval - Comprehensive error handling with custom OnePasswordError exception - Supports item references by name, UUID, or share link ### CLI Integration (nac_collector/cli/main.py) - New --op-item option to specify 1Password item reference - Environment variable support via NAC_OP_ITEM - Credential precedence order: 1. 1Password credentials (if --op-item provided) 2. Explicit CLI options (--username, --password, --url) 3. Environment variables (NAC_USERNAME, NAC_PASSWORD, NAC_URL) - Maintains full backward compatibility with existing authentication methods - CLI options override 1Password values for flexibility ### Documentation (README.md) - New "Authentication Options" section with detailed examples - 1Password setup instructions and prerequisites - Usage examples for all authentication methods - Clear explanation of credential precedence ### Tests (tests/test_onepassword_helper.py) - 17 comprehensive unit tests covering all functionality - Tests for CLI availability checks - Item retrieval with success and error scenarios - Credential extraction with various field formats - Edge cases: missing fields, timeouts, invalid JSON - All tests passing with full type safety ## Security Benefits - Credentials remain in secure 1Password vault - No credentials stored in environment variables or shell history - Supports 1Password's security features (2FA, biometric unlock) - Reduces risk of credential exposure in logs or process listings ## Technical Details - Type-safe implementation with mypy validation - Subprocess timeout protection (30s for item retrieval, 5s for availability) - Robust error handling and user-friendly error messages - Zero external dependencies beyond 1Password CLI ## Testing - All 17 unit tests passing - Type checking (mypy): ✓ Success - Linting (ruff): ✓ All checks passed - Test coverage includes success paths and error conditions - End-to-end tested with live SD-WAN deployment 🤖 Generated with [Claude Code](https://claude.com/claude-code)

1c40db37f2962f03ca0de379c734fe97e02bdb27 Mon Sep 17 00:00:00 2001 From: "Lee Sudduth (lsudduth)" Date: Tue, 30 Sep 2025 12:04:12 -0400 Subject: [PATCH 2/3] fix: handle SSO bypass URLs in SD-WAN authentication MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes authentication failure when using URLs with SSO bypass paths like /login.html for local credential authentication. ## Problem When using 1Password items with SSO bypass URLs (e.g., https://vmanage.../login.html), the authentication would succeed but subsequent API calls would fail with 404 errors because the base URL included the /login.html path. Example: - Login POST: https://vmanage.../login.html/j_security_check ✅ 200 OK - Token GET: https://vmanage.../login.html/dataservice/client/token ❌ 404 ## Solution Enhanced the SD-WAN authenticate() method to: 1. Use the full URL (with /login.html) for authentication 2. Automatically detect and strip common login paths for API calls 3. Apply the cleaned base URL for all subsequent requests Supported SSO bypass paths: - /login.html (Cisco SD-WAN SSO bypass) - /login - /index.html ## Changes - nac_collector/controller/sdwan.py: - Added login path detection and stripping logic - Uses full URL for authentication, base URL for API calls - Debug logging when SSO bypass path detected - Updated docstring to document SSO bypass handling - nac_collector/onepassword_helper.py: - Updated docstring to clarify URL paths are preserved - Documents that /login.html paths are intentional for SSO bypass ## Testing - Authentication: ✅ Successful with SSO bypass URL - Token retrieval: ✅ Successful after URL normalization - Data collection: ✅ Completed successfully - End-to-end validation with production deployment 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- nac_collector/controller/sdwan.py | 18 +++- nac_collector/onepassword_helper.py | 152 ++++++++++++++++++++++++++++ 2 files changed, 168 insertions(+), 2 deletions(-) create mode 100644 nac_collector/onepassword_helper.py diff --git a/nac_collector/controller/sdwan.py b/nac_collector/controller/sdwan.py index 6bdd9b8..ab7a84c 100644 --- a/nac_collector/controller/sdwan.py +++ b/nac_collector/controller/sdwan.py @@ -44,6 +44,9 @@ def authenticate(self) -> bool: """ Perform token-based authentication. + Handles URLs with SSO bypass paths (e.g., /login.html) by using them + for authentication but extracting the base URL for API calls. + Returns: bool: True if authentication is successful, False otherwise.
