[squid-users] Re: Kerberos: HTTP/<host> and not HTTP/<host.fqdn>@FQDN

Hi Nick,

  This is a unusual setup. I wonder how you could get it to work as a keytab
extraction changes usually the AD entry and therefore the key for your
2nd/3rd squid server. I suggest to create three separate AD entries and
remove any SPN for HTTP/<short-hostname>.

Regards
Markus

Hi list,

I think I have a problem with one of my SPNs/keytab - wondered if someone
could confirm this:

3 x squid boxes on different sites, squid1, squid2 and squid3 are their
hostnames. I have one AD account with the SPNs of all on it. Using fqdn for
the proxy address to 2 of them results in Kerberos tickets:
HTTP/<squid1>.fqdn_at_FQDN and HTTP/<squid2>.fqdn_at_FQDN and everything is fine.

However on the third one I get a ticket: HTTP/squid3@ i.e. No fqdn or @FQDN

I have both 'squidx' and 'squidx.fqdn' in my AD SPN for all boxes. I'm
thinking the working two are using the squid.fqdn and the non-working one is
using just 'squid3' hence the issue. Does this sound feasible. I think the
answer is drop the 'squidx' from my SPNs and stick with the 'squidx.fqdn',
regenerate my keytab and that's it.

I have cloned one of the working squid boxes and replaced the non-working
one, so this leads me to believe it is the SPN/keytab and not the server.

Thoughts welcome!
