mod_dav_svn returns generic 401 for expired LDAP passwords with no way to distinguish them from bad credentials

Goal I want a Subversion repository served by Apache httpd with mod_dav_svn and LDAP authentication to handle expired passwords in a predictable, least-privilege way: once a user's LDAP password expires, access should stop immediately and the failure should be identifiable as an expiration rather than a wrong password. Constraints and uncertainty From what I

FoundationDB Transaction Retry: Server-Side Idempotency Token Absence

Context FoundationDB's optimistic concurrency control returns retryable errors ( transaction_too_old , not_committed ) when read-write conflicts occur. The on_error callback automatically re-executes the entire transaction function, which re-applies any writes unless the application implements idempotency at the key level. Constraint Current patterns require

Named query visibility scope and accidental public access in kdeneon

This question addresses the diagnosis of named query visibility scope within kdeneon's access‑control framework to prevent accidental public exposure. The supported feature is the Hibernate‑style named query definition, which enables static SQL reuse across sessions, and its interaction with kdeneon's permission model requires careful configuration.

URLSessionDelegate vs TrustKit for SSL Pinning

Implementing SSL pinning in a Swift application requires a choice between utilizing the native URLSessionDelegate for manual trust evaluation or integrating a third-party library like TrustKit. Using the native urlSession(_:didReceive:completionHandler:) method allows for direct control via SecTrustRef and eliminates external dependencies, reducing binary si

PKCE S256: Minimum code_verifier length enforcement in OAuth 2.0 authorization servers

When implementing the Proof Key for Code Exchange (PKCE) extension with the S256 challenge method, authorization servers must verify that the submitted code_verifier matches the previously stored code_challenge. While RFC 7636 recommends a code_verifier length of 43 to 128 characters using unreserved characters, many client libraries accept shorter values, a

Tailwind CSS v3 introduced the content configuration key to replace the legacy purge key, with the old key still accepted but emitting a deprecation warning ahead of removal in a future major release. A migration plan needs to move file globs and safelist entries from purge to content while maintaining consistent class generation across builds. The configura
