Hi Guys, I have been running squid with AD authentication and security group authent= ication for the last 6 months, and suddenly squid failed with the following= message (squid): Too many queued ntlmauthenticator requests. Iam using samba-3.4.8-59.fc12.x86_64 samba-winbind-clients-3.4.8-59.fc12.x86_64 samba-common-3.4.8-59.fc12.x86_64 samba-client-3.4.8-59.fc12.x86_64 samba-winbind-devel-3.4.8-59.fc12.x86_64 samba-winbind-3.4.8-59.fc12.x86_64 Squid Cache: Version 3.0.STABLE24 configure options: '--prefix=3D/usr/local/squid' '--enable-auth=3Dntlm,bas= ic' '--enable-external-acl-helpers=3Dwbinfo_group' and also iam getting the following error [2010/10/18 10:28:58, 3] winbindd/winbindd_cm.c:1597(connection_ok) connection_ok: Connection to for domain xxx is not connected (but if I use the net join command it says joined to domain) According to my squid report normally there are 700 people connecting to th= e proxy, but now its says winbind maximum connection exceeds 200, but iam = confusing about that. Appreciate your help on this. Best regards, Tharanga
