I've found an old post taking about edirectory, so i modified the query like that: usr/sbin/squid_ldap_group -Z -D cn=squid,o=laboratorio -w "novell" -b o=laboratorio -s sub -f "(&(objectClass=User)(cn=%u)(groupMembership=cn=%g,o=laboratorio))" -h 192.168.0.205 -p 389 and now just entering username groupname shows OK. So it looks like on the ldap filter, for the groupname i had to specify manually the context where it is, even if it is under the search base. Now i have to test it on the browser login page. Thanks Gonzalo >>> "Gonzalo Morera" <gmorera@xxxxxxxxxx> 31/1/2011 10:32 AM >>> I saw now that if i enter the query on the bash: usr/sbin/squid_ldap_group -Z -D cn=squid,o=laboratorio -w "novell" -b o=laboratorio -s sub -f "(&(objectClass=User)(cn=%u)(groupMembership=%g))" -h 192.168.0.205 -p 389 when cursor blinks i enter: username group Then i've got squid_ldap_group Warning, ldap search error "invalid dn syntax" So it looked like the query sent is incorrect. But if i enter: username cn=groupname,o=context Then i';ve got Connected OK and groupfilter OK So it looks like this is my issue, the query sent is incorrect. From bash i can easily modify it and add cn=group,o=context to perform the search but how can i apply that to the acl? here im lost. Thanks a lot Gonzalo >>> "Gonzalo Morera" <gmorera@xxxxxxxxxx> 31/1/2011 09:45 AM >>> Hi all After getting familiar with the squid_ldap_auth, i'm still having some issues with squid_ldpa_groups. I'm getting familiar with squid acl ( i've been working last years with novell bordermanager what is quiet different) and i can not make it work I've got two groups, internet_r and internet_nr. I'm using a pl file to allows users with the novell client installed, transparently access internet. That works fine as the pl scrip gets the network ip address of the client. But, with no novell client install, the default ldap_auth method has to be used, so users get a log in page to enter name and password. After done it, same page appears and after 3 times and access denied is seen. No matter if i use a user on group internet_r (with access) or internet _nr ( no access) the results are the same. THe login page keeps returning till the access denied. so i'm doing something wrong with squid_ldap_group and acl. Looking at lan traces, i saw nothing and access.log file showed no errors, only the url user wanted to go. Var/log/message showed as well no indication of any error. So how can i see in more details what is happening? This is my squid.conf #Recommended minimum configuration: auth_param basic program /usr/sbin/squid_ldap_auth -Z -D cn=squid,o=laboratorio -w novell -b o=laboratorio -s sub -f "(&(objectclass=User)(cn=%s))" -h 192.168.0.205 -p 389 auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off #Default: # none #external_acl_type directory_group %LOGIN /usr/sbin/squid_ldap_group -R -b "ou=servicios,o=laboratorio" -D "cn=admin,o=laboratorio" -w "synergy" -f (&(objectClass=person)(uid=%v)(groupMembership=cn=%a,ou=servicios,o=laboratorio))" -h 192.168.0.205 -p 389 # external_acl_type IPUser ttl=7200 %SRC /etc/squid/squid_edir_iplookup.pl # #este vale external_acl_type ldap_group %LOGIN /usr/sbin/squid_ldap_group -R -b "o=laboratorio" -D "cn=squid,o=laboratorio" -w "novell" -f (&(objectClass=inetOrgPerson)(cn=%u)(groupMembership=%g))" -h 192.168.0.205 -p 389 external_acl_type ldap_group %LOGIN /usr/sbin/squid_ldap_group -Z -D cn=squid,o=laboratorio -w "novell" -b o=laboratorio -s sub -f "(&(objectClass=User)(cn=%u)(groupMembership=%g))" -h 192.168.0.205 -p 389 Message looks good when loading: Jan 27 12:26:59 oes2sp1 squid[11312]: Squid Parent: child process 11314 started Jan 27 12:26:59 oes2sp1 squid[11314]: Starting Squid Cache version 2.5.STABLE12 for i686-pc-linux-gnu...
