 * IMPORTANT: This is an ODR (One Definition Rule) violation.
 * DO NOT copy this pattern in production code or other contexts.
 *
 * Background: GloMyLdapAuth is declared as 'extern' in multiple source files in the 'lib' directory.
 * Since unit tests link against ProxySQL libraries without the full binary, this causes linker errors.
 *
 * This definition provides a stub implementation to satisfy the linker when building unit tests.
 * This is acceptable because:
 *   1. Unit tests are standalone executables that don't share symbols with each other
 *   2. This is a temporary workaround until the include hierarchy is properly refactored
