+/*
+ * Uncommenting this will enable the built-in debug logging of the openldap
+ * library. The debug log level can be set using the CURL_OPENLDAP_TRACE
+ * environment variable. The debug output is written to stderr.
+ *
+ * The library supports the following debug flags:
+ * LDAP_DEBUG_NONE 0x0000
+ * LDAP_DEBUG_TRACE 0x0001
+ * LDAP_DEBUG_CONSTRUCT 0x0002
+ * LDAP_DEBUG_DESTROY 0x0004
+ * LDAP_DEBUG_PARAMETER 0x0008
+ * LDAP_DEBUG_ANY 0xffff
+ *
+ * For example, use CURL_OPENLDAP_TRACE=0 for no debug,
+ * CURL_OPENLDAP_TRACE=2 for LDAP_DEBUG_CONSTRUCT messages only,
+ * CURL_OPENLDAP_TRACE=65535 for all debug message levels.
