Hi, I have currently setup one of the squid proxy servers to use a /usr/lib/squid/wbinfo_group.pl to do group lookups. I am noticing a performance hit when using multiply groups after turning on logging every user authentication requires a lookup in all the groups. I am also using NTLM which also is hurting me. Can any one point me in a direction to make group lookups faster? Should I be looking at LDAP instead? Text file? Group membership does change as I kick students on and off the internet. Domain has 1000 users including students and staff. Running Version 2.5.STABLE3 Sample ACL?s acl network1 src 192.168.1.1-192.168.1.254 acl network2 src 192.168.200.1-192.168.200.128 acl staff external nt_group internet-staff acl junior external nt_group junior acl senior external nt_group senior http_access allow network1 staff http_access allow nettwork2 staff http_access allow network1 junior http_access allow network2 senior ? Any help or urls would be greatly welcomed. Ttyl, Allen Armstrong
