Authentication Plugins •When the plugin unloads, it closes all pooled connections. Changes to plugin system variable settings may have no effect on connections already in the pool. For example, modifying the LDAP server host, port, or TLS settings does not affect existing connections. However, if the original variable values were invalid and the connection pool could not be initialized, the plugin attempts to reinitialize the pool for the next LDAP request. In this case, the new system variable values are used for the reinitialization attempt. If  authentication_ldap_sasl_max_pool_size=0  to disable pooling, each LDAP connection opened by the plugin uses the values the system variables have at that time. • authentication_ldap_sasl_log_status Command-Line Format --authentication-ldap-sasl-log- status=# System Variable authentication_ldap_sasl_log_status Scope Global Dynamic Yes SET_VAR  Hint Applies No Type Integer Default Value 1 Minimum Value 1 Maximum Value ( ≥  8.0.18) 6 Maximum Value ( ≤  8.0.17) 5 For SASL LDAP authentication, the logging level for messages written to the error log.
