Can you run both squid_kerb_ldap and squid_kerb_auth with -d. It should give
a lot more details to find out why it happens

Hello,
I'm having an issue with squid_kerb_auth. It seems not all proxy
requests are getting serviced. When falling back on NTLM the requests
come though fine.
My guess is subsequent GET requests made over Proxy_KeepAlive sessions
are not getting serviced. I confirmed this on a trace using Wireshark
where the client requests a page but Squid doesn't come back with an
answer. Is this a known issue?
I'm currently running squid3-3.1.6 and have seen this behavior both
with the include squid_kerb_auth and a seperately compiled binary.
squid.conf follows:
