Hai Rowland,
Yes, the configs below are currently working on Debian Jessie, in production.
Only debian packages are used from Jessie.
and sorry for the big email, i alway try to keep is short but that never works
out ... :-/
The apache config, is a setup for Zarafa Single Sign On.
basicly this setup,
https://community.zarafa.com/pg/blog/read/18332/zarafa-outlook-amp-webaccess-sso-with-samba4
which works great. I tested this one on debian wheezy and jessie and ubuntu
12.04 and 14.04
The site explains the settings.
for this settins : KrbServiceName HTTP
if you create your spn like : samba-tool spn add HTTP/zarafa-server
you can force the use of the HTTP, without it, it can be http/zarafa-server
also, which you dont want.
spn's must be an exact match.
>> KrbMethodNegotiate On
>> KrbMethodK5Passwd Off
disable the use of password based authentication for Kerberos v5
Users are not allow to type a password here, the must be passthrough auth with
kerberos.
so if it fails to authenticate you wil never reach the website, and that what i
want.
( if i did understand these settings well )
i have 2 setups for my apache, want for internal user, (above).
and one for external user, not posted here, only a select group of users is
allowed to use
webmail from outside the office. We dropped outlook here, and started use-ing
zarafa-webapp.
This was needed to make sure certain info can not be leaked out of the office.
And for the squid configs. The order is also the order in my working config.
first kerb auth, used for passthrough authentication, with firefox and Internet
Explorer,
( same as needed for my zarafa server) no passwords are typed here.
Then the ldap AD auth, then ldap basic auth.
Kerberos for internal AD/users.
LDAP AD, for users which dont authenticate in the AD, but which do need
internet. typed password
LDAP Basic, for my quest users. typed password.
Radius is the next step, but im not here yet. ;-)
There is a only 1 men IT department here.. me.. so lots of things to do.
This is the full set i have for squid.
I've made this setups, because there are lots of "not working/to
complex/half" setups/howtos.
Depending on how you want to use your squid, you select the config files.
squid-01-01-auth-GSS.conf => auth_param negotiate program /usr/bin/ntlm_auth
--helper-protocol=gss-spnego
Works only with samba4 , not tested yet.
squid-01-01-auth-KERB.conf => auth_param negotiate program
usr/lib/squid3/negotiate_kerberos_auth
-s HTTP/hostname.internal.domain.tld at INTERNAL.DOMAIN.TLD
the kerberos ticked is used for auth. no UID needed. no passwords are typed.
here, extra settings are needed in the pc's. I used GPO for that, also
needed for the zarafa SSO.
for that see the site :
https://community.zarafa.com/pg/blog/read/18332/zarafa-outlook-amp-webaccess-sso-with-samba4
which explains a lot.
squid-01-02-auth-AD-ldap.conf => auth_param basic program
/usr/lib/squid3/basic_ldap_auth -R (-R do not follow referencials )
-D ldapbind at internal.domain.tld resulting in the userPrincipalName or
sAMAccountName AD entries.
NO uid needed, passwords are typed.
squid-01-03-auth-ldap-basic.conf => auth_param basic program
/usr/lib/squid3/basic_ldap_auth -v 3 -f uid=%s
you also see a different way for the ldapbind user, this one also works with
samba 3. ( not het tested on samba4, but should works also)
resulting in the UID for the users. so UID is needed, passwords are typed.
squid-01-01-auth-NTLM.conf auth_param ntlm program /usr/bin/ntlm_auth
Should works with samba3 and samba 4 but this one is not tested yet.
-- i use include *.conf for my squid setup and the numbers in the file names,
make that i can put extra settings in.
without touching any other squid config, imo this makes the squid config more
easy to handle.
I have 2 squid server, with 1 user for the SPNs.
Created like this. username=squid-proxy
samba-tool user create squid-proxy --description="Unprivileged user for
SQUID-Proxy Services" --random-password
samba-tool user setexpiry squid-proxy --noexpiry
echo "setting HTTP SPN on the proxy user (proxy1)"
samba-tool spn add HTTP/proxy1.internal.domain.tld squid-proxy
samba-tool spn add HTTP/proxy1.internal.domain.tld at INTERNAL.DOMAIN.TLD
squid-proxy
echo "setting HTTP SPN on the httpd user (proxy2)"
samba-tool spn add HTTP/proxy2.internal.domain.tld squid-proxy
samba-tool spn add HTTP/proxy2.internal.domain.tld at INTERNAL.DOMAIN.TLD
squid-proxy
samba-tool domain exportkeytab --principal=HTTP/proxy1.internal.domain.tld
/root/keytabs/proxy1.keytab
samba-tool domain exportkeytab --principal=HTTP/proxy2.internal.domain.tld
/root/keytabs/proxy2.keytab
and the ldapbind users, which can be used for multiple things.
samba-tool user create ldap-bind --description="Unprivileged user for LDAP
bind connections" --random-password
samba-tool user setexpiry ldap-bind --noexpiry
When done, you must reset the password to a know password, the password wil not
expire.
and we put the password in the file /etc/squid3/private/ldapbind
this is used for my zarafa setup.
!! zarafa has 2 users hardcoded zarafa-linux and httpd-linux !!
samba-tool user create zarafa-linux --description="Unprivileged user for
Zarafa Services" --random-password
samba-tool user create httpd-linux --description="Unprivileged user for
Apache/zarafa Services on HOSTNAME.DOMAIN.TLD" --random-password
samba-tool user setexpiry zarafa-linux --noexpiry
samba-tool user setexpiry httpd-linux --noexpiry
samba-tool spn add zarafa/hostname.domain.tld zarafa-linux
samba-tool spn add zarafa/hostname.domain.tld at INTERNAL.DOMAIN.TLD
zarafa-linux
samba-tool spn add HTTP/hostname.domain.tld httpd-linux
samba-tool spn add HTTP/hostname.domain.tld at INTERNAL.DOMAIN.TLD httpd-linux
samba-tool domain exportkeytab --principal=zarafa/hostname.domain.tld
~/keytabs/hostname-zarafa-zarafa.keytab
samba-tool domain exportkeytab --principal=HTTP/hostname.domain.tld
~/keytabs/hostname-http-zarafa.keytab
and dont forget to set the needed rights on the apache keytab file
chown www-data:www-data hostname-http-zarafa.keytab
chmod 400 hostname-http-zarafa.keytab
Greetz,
Louis
