Hi to all.
I want to block web.whatsapp.com in some users.
But i already have those users in other group.
I suppose this is not a problem if i put the acl in some order... but its
not working.
For example, i have group
I-FULL: user1, user2, user3
I-RESTRINGIDOS: user1
This is my config file
####GRUPOS DE IP
acl sin_autenticacion src "/etc/squid/listas/sin_autenticacion.lst"
###Kerberos Auth with ActiveDirectory###
auth_param negotiate program /lib64/squid/negotiate_kerberos_auth -s
HTTP/squid.domain.lan at DOMAIN.LAN
auth_param negotiate children 35 startup=0 idle=1
auth_param basic credentialsttl 2 hours
auth_param negotiate keep_alive on
external_acl_type i-restringidos %LOGIN
/usr/lib64/squid/ext_kerberos_ldap_group_acl -g i-restringidos at DOMAIN.LAN
external_acl_type i-full %LOGIN /usr/lib64/squid/ext_kerberos_ldap_group_acl
