Hi Sarfraz,
You didn't say which helper you are running and with which options. The
message you get should have nothing to do with authentication but with
authorisation (if you use kerberos_ldap_group). You may get a similar
message on the Windows client as part of the Kerberos exchange in the TGS
reply.
Can you do an AD search for an entry with
userprincipalname=HTTP/squidkhi1.mailserver.mcb.com.pk ?
What encryption types you get when running klist -ekt <squid.keytab> ?
2008 may require AES ( If you check the wiki
http://wiki.squid-cache.org/ConfigExamples/Authenticate/Kerberos you will
see how to create a keytab for 2008 )
Regards
Markus

Subject: Re: Keytab client not found in kerberos database
Hi Sarfraz,
Which helpers do you run ? The message you see is most probably from the
kerberos_ldap_group helper and means that when the helper tries to
authenticate to AD the AD entry with an attribute
userprincipalname=HTTP/<squid-fqdn> can not be found.
squid-fqdn being the name you have in your squid keytab ( You can check
with klist -kt <squid.keytab> if you use MIT or ktutil -k <squid.keytab>
list for Heimdal).
