Hi everyone I'm looking for some inspiration because I am drawing a complete blank! A few years ago I set up my company's squid boxes - a pair of servers both identically configured and using LDAP authentication against an Active Directory domain. It took quite some time to get it all working properly but eventually it all got going and ran smoothly. I then left the company for a spell and now find myself back and detailed with rebuilding the squid servers onto newer boxes because the hardware is a little long in the tooth and now the software is too - the original servers were on RHEL 3 boxes and the subscriptions to get updates were never renewed.
One of the servers failed and has been replaced with a newer box which I have built, as instructed, with CentOS 5. All seems okay but when I transplant the config file from the (now very hard-working) live machine I am getting an LDAP error with the lookup. Clearly I either missed installing something fundamental when I built the server (the idiot scenario) or something has changed syntactically with the options but I have searched diligently through the man pages and can't find any reason why what did work no longer works. Here is the line from squid.conf working on the live box (2.5.STABLE3): auth_param basic program /usr/lib/squid/squid_ldap_auth -b "dc=cs-plc,dc=salvesen,dc=com" -D "cn=Ldap User,ou=users,ou=ND House (slh / wel),ou=UK,dc=cs-plc,dc=salvesen,dc=com" -w (password) -f "(&(sAMAccountName=%s)(memberOf=CN=InternetUsers,OU=Groups,OU=ND House (slh / wel),OU=UK,DC=cs-plc,DC=salvesen,DC=com))" -h 10.1.2.1 -p 3268 The new box where this doesn't work is at 2.6.STABLE6. Attempts to authenticate result in the logfile showing: squid_ldap_auth: WARNING, LDAP search error 'Bad search filter' Has anybody got any insight? At present I've cut back the filter to -f "sAMAccountName=%s" which is at least forcing authentication but not checking the group membership.
