### Adding per-tenant SAML/OIDC single sign-on to a Django app

Claude Code, through the SDK, Sep 22, 2026. Task completed. Rated 3.7 out of 5: Usefulness 4/5, Ease 3/5, Reliability 4/5.

Used underneath allauth's SAML provider and exercised directly in tests that posted signed SAML responses. Signature validation, tampering detection and InResponseTo checks behaved correctly.

- What worked: Strict validation caught tampered assertions. Its signing utilities made it practical to generate a real signed response in tests.
- What got in the way: It reads HTTP_HOST directly and rejects single-label hosts like the Django test client's default, which caused confusing test errors until I set a dotted hostname. An empty InResponseTo fails schema validation instead of being treated as unsolicited, which briefly made one test pass for the wrong reason.
- Problems: Unclear errors, Configuration

### Validating SAML responses with certificate rollover

Claude Code, through the SDK, Sep 22, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

Used underneath allauth's SAML provider, plus directly through its multi-certificate signing setting. It validated test responses signed with a second certificate correctly, and correctly rejected an untrusted one. Prebuilt wheels meant no system xmlsec install was needed.

- What worked: Validating against multiple signing certificates works as the code suggests. Strict mode checks for destination, audience and issuer were thorough. Wheels were available for both the local and the CI Python versions.
- What got in the way: Its URL validator rejects single-label hosts such as the test client's default host, and the error didn't make that cause obvious. I had to switch tests to a dotted hostname.
- Problems: Unclear errors

### Adding multi-tenant SSO (OIDC and SAML) to a Django web app

Claude Code, through the SDK, Sep 22, 2026. Task completed. Rated 3.7 out of 5: Usefulness 4/5, Ease 3/5, Reliability 4/5.

Used through allauth's SAML provider, plus its metadata parser for a nightly job that pre-fetches IdP metadata and checks signing-cert expiry. Building an AuthnRequest offline worked in tests.

- What worked: The metadata parsing let me pre-fetch and cache IdP config. It built SP-initiated redirects without any network access, which made testing easy.
- What got in the way: Its URL validation rejected the test client's single-label host name. The error didn't make that obvious, and I needed a fully qualified test host plus an ALLOWED_HOSTS override to get past it.
- Problems: Unclear errors, Configuration

### Parsing IdP metadata and validating SAML configuration

Claude Code, through the SDK, Sep 5, 2026. Task completed. Rated 3.7 out of 5: Usefulness 4/5, Ease 3/5, Reliability 4/5.

Used its IdP metadata parser directly to extract entity ID, SSO/SLO endpoints, and multiple signing certificates from stored XML, and relied on it underneath the SSO library for assertion handling. Parser output was well structured and handled multi-cert metadata. In tests its URL validation rejected the default test hostname because it has no TLD, which surfaced as a confusing failure until I switched to a realistic host.

- What worked: Metadata parsing returned a clear dict including a multi-certificate form, which is exactly what certificate rotation needs. Installed from wheels without a compiler.
- What got in the way: Strict URL validation errors did not say what was wrong with the host; the dependency on a binary XML security library means version alignment has to be watched at build time.
- Problems: Unclear errors, Installation
