Wel first, great, you made it to install it,
Yes, but your auth pop-up can be normal, but we need more info, this can be multple things.
So, few small questions.
1) is the time in sync with the proxy and AD server?
2) Did you set the krb5.conf with or without the enctypes types?
3) Which browser are you using?
4) Did you configure the browser to use the kerberos auth?
5) Did the PC join the domain, and are u using a domain user login?
6) Does kinit user at REALM work? ( kdestroy to remove the user ticket )
7) Last, does the proxy server have an A and PTR record?
Also check this site, review your settings.
https://ping.force.com/Support/PingFederate/Integrations/How-to-configure-supported-browsers-for-Kerberos-NTLM
And last tip your auth line.
auth_param negotiate program /usr/lib/squid/negotiate_kerberos_auth -s HTTP/hostname.domain.org at DOMAIN.ORG
Can also be a problem so test, if the upn is setup incorrectly, then above does not work, below the should work.
auth_param negotiate program /usr/lib/squid/negotiate_kerberos_auth -s GSS_C_NO_NAME
add -d to get more debug info.
greetz,
Louis

Onderwerp: missing negotiate_kerberos_auth on my squid
Hello All;
Configured the steps require for kerberos authentication as given at http://wiki.squid-cache.org/ConfigExamples/Authenticate/Kerberos
but instead of SSO to work when we try to open url; it is prompt for username and password, when passing credential it is not authenticating.
attached is our squid config for your reference.
Kindly let us know what went wrong.
we are using windows 2012 AD.
Thanks & Regards

Thanks louise for reply.
but
Should be include imo. -- not sure what is imo
Shoud be in any Squid-3.2 and later.
And on my debian server its locate here.
/usr/lib/squid/negotiate_kerberos_auth - check the path but it is not there on my linux box.
Did you enable : --enable-auth-negotiate=kerberos,wrapper on compile ? ---- NO didn't gave this option while compilation
Run squid –v to check it. -- we have"--enable-auth-negotiate" only and some other configured option.

Agreed.

It is not possible today: Converting ICAP headers into annotations
understood by Squid ACLs is only supported for eCAP services.
IIRC, somebody posted a patch (on squid-dev) with a similar feature for
ICAP, but that implementation needed to be redone to be officially
accepted (IMO). I do not know whether the author will adjust their code
to follow my recommendations. Perhaps you can do it for them.

Hi
I am using squid as a reverse.
#http_port 80 accel defaultsite=202.53.13.19
https_port 443 accel cert=/var/www/html/webrtc/imp/teleuniv.net.crt
key=/var/www/html/webrtc/imp/teleuniv.net.key
cafile=/var/www/html/webrtc/imp/intermediate.crt defaultsite=202.53.13.19
no-vhost
#this ACL is url path specific which accepts only portal urls and deny
others.
acl portal urlpath_regex ^/portal6may
cache_peer 172.20.36.144 parent 80 0 no-query originserver name=portalserver
cache_peer_access portalserver allow portal
cache_peer_access portalserver deny all
http_access allow portal
cache_peer 172.20.36.150 parent 443 0 no-query originserver ssl
sslflags=DONT_VERIFY_PEER login=PASS connection-auth=off name=teleuniv
acl our_sites dstdomain 202.53.13.19
http_access allow our_sites
cache_peer_access teleuniv allow our_sites
cache_peer_access teleuniv deny all
SO when i try to access the url MailScanner warning: numerical links are often malicious: https://202.53.13.19/ I get the following
error
"The following error was encountered while trying to retrieve the URL: The
system returned: (111) Connection refused; The remote host or network may
be down. Please try the request again."
It only gives for 172.20.36.144 not for the urlpath acl. But this happens
only sometimes. When I physically go to that server (172.20.36.150) and
click on the wired connection (one of the LAN options using linux). It
works again. I am very confused

If it ended with some kind of server issues else then the logs, then it would be considered not nice.

Hello ;
I have installed latest squid 3.5.19 on red hat Linux yesterday. That
means I am new to squid and linux.
able to start the squid and its working fine.
now we are trying to authenticate user via Kerberos with windows AD. but
facing issues.
followed the steps provided on
http://wiki.squid-cache.org/ConfigExamples/Authenticate/Kerberos
But unable to find negotiate_kerberos_auth on my Linux box at any
location.
now I need to know where i can find/download negotiate_kerberos_auth and
compile it to make authentication successful.
Thanks & Regards
