Hi all, Since upgrading to squid 2.6-S1 I get a lot of these in cache.log: assertion failed: authenticate.c:836: "auth_user_request != NULL" This restarts squid every 30 minutes or so. I call ntlm as follows: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param ntlm keep_alive on Samba is working well and I don't see any errors in the samba logs. --- Chris Covington IT Plus One Health Management 75 Maiden Lane Suite 801 NY, NY 10038 646-312-6269 http://www.plusoneactive.com
