Hi Jeroen,
Do you use Active Directory as ldap server ? My automated test says it is
not. I use this check to determine the group attribute check.

the end of the whole listing

I'm trying to replace my basic ldap authentication by kerberos single

NP: Despite what some claim, SSO is not unique to NTLM and Kerberos
authentication. It is a behaviour of the tools used. As such it can be done
with *any* authentication type if the tools used perform the necessary
behaviour.
The user can succesfully login with single sign on, but I have
restriction on groups and that is where it goes wrong.
What exactly does this "going wrong" look like?
Also, what version of Squid are you working with?
(the "squid -v" output please)
I would like to use -r to trim the domain name, but when I do so it
seems to work even less.
Someone any ideas what to try, I believe the system is loking wrong in
active directory but adding -b OU=Users,DC=yyy,DC=local does not help
me further
You have some things looking for ".local" and others for ".LOCAL". I'm not
sure if case insensitivity exists in all those places they are being used,
so that is one potential cause of problems.

-d
acl XXX_InternetAllowed external XXX_InternetAllowed
acl XXX_Adult external XXX_Adult
...
http_access deny auth !XXX_InternetAllowed
The above says the users entire login is to be rejected if they are not a
member of the XXX_InternetAllowed group.
That should work but it is better to reject failed logins fully first, then
do the group checks separately.
Like this:
http_access deny !auth
http_access deny !XXX_InternetAllowed all
http_access deny XXX_Adult XXX_AdultX
you could gain a fair bit of performance back by making that check the
dstdomain before the slow external lookup:
http_access deny XXX_AdultX XXX_Adult all
http_access allow localnet
http_access allow localhost
http_access deny all

Looks like it is working to me.
The helper tries several methods of locating a server, two fail but the
third seems to work and produces the above result.
