Thanks for the response, Guido. That was as I thought - that it was a client sending some kind of bad credentials; still doesn't tell me *which* client though! And as authenticator log entries aren't time stamped I can't even try to correlate them with TCP_DENIED entries in access.log. As asked in the OP, is there a debug_level parameter that can be used to trace requests sent to authenticator helper processes? None of the candidates in debug-sections.txt seem quite right, unless section 28 is the one. Regards Euan
