See squid.conf below.. Any other config files you need to see?

The users authenticating via ldap on phones are in an Active directory group listed in the file /etc/squid/full_access.txt - They do get full internet access when authenticating via kerberos.

I've checked they are entering the correct passwords - although there are special characters in the passwords eg. `^( - Not sure if that could make a difference. Like I said, it works when running basic_ldap_auth on the command line.
