When LDAP authentication fails due to TLS certificate validation errors (e.g., "unable to get local issuer certificate"), these failures are not captured in the default log level of authentication-mgr or user-manager. As a result, administrators must enable debug logging to obtain useful diagnostic information about the failure.
- Administrators are unable to diagnose LDAP/TLS authentication failures using standard logs. - Additional troubleshooting steps (enabling debug logging) are required to obtain error details. - Increases time to resolution and may delay identification of root cause for authentication issues.
Running F5OS-C 1.8.1 (VELOS platform) or lower version. LDAP authentication is configured for the system.
Enable debug logging for authentication-mgr and user-manager to capture detailed error messages related to LDAP/TLS failures.
