Hi Rob,
What happens when you type kinit HTTP/proxyserver.paragould.psd on your kdc
server ? Do you get a password prompt ?

Hi Markus,
I created the service principal with kadmin on the apple server. The
actual command was kadmin.local -q "add_principal
HTTP/proxyserver.paragould.psd". I used kadmin also to export the keytab.
Here's exactly what I did:
xserve:~ root# kadmin.local
Authenticating as principal root/admin@xxxxxxxxxxxxxxxxxxxx with password.
kadmin.local: xst -k proxyserver.keytab
HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
Entry for principal HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
with kvno 5, encryption type Triple DES cbc mode with HMAC/sha1 added to
keytab WRFILE:proxyserver.keytab.
Entry for principal HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
with kvno 5, encryption type ArcFour with HMAC/md5 added to keytab
WRFILE:proxyserver.keytab.
Entry for principal HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
with kvno 5, encryption type AES-128 CTS mode with 96-bit SHA-1 HMAC added
to keytab WRFILE:proxyserver.keytab.
Entry for principal HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
with kvno 5, encryption type AES-256 CTS mode with 96-bit SHA-1 HMAC added
to keytab WRFILE:proxyserver.keytab.
kadmin.local: q
xserve:~ root# klist -k proxyserver.keytab
Keytab name: WRFILE:proxyserver.keytab

HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
HTTP/xserve.paragould.psd@xxxxxxxxxxxxxxxxxxxx
http/xserve.paragould.psd@xxxxxxxxxxxxxxxxxxxx
That last command to list the http principals confused me and I'm not
familiar with kerberos at all really. Is it showing there are http service
principals for both proxyserver.paragould.psd and xserve.paragould.psd or
does the KDC automatically add a http service principal for itself too? In
this case, xserve.paragould.psd is the KDC server running on OS X Server
10.6.2 and proxserver.paragould.psd is the squid server running on CentOS
5.5. I copied the exported proxyserver.keytab to /etc/squid/ on the host
proxyserver.paragould.psd and made sure the squid user had read access to
it. Running kinit squidserver and giving it's password works I think.
klist after that shows:
[root@proxyserver squid]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: squidserver@xxxxxxxxxxxxxxxxxxxx
Valid starting Expires Service principal
12/08/10 15:38:42 12/09/10 01:38:42
krbtgt/XSERVE.PARAGOULD.PSD@xxxxxxxxxxxxxxxxxxxx
renew until 12/09/10 15:38:42
Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached
I'm sure I've missed something or messed something up but I'm at a loss as
what it is or where to even start looking. Thanks for any help!
Regards,
Rob

Hi Rob,
It looks like your kdc does not know about the service principal
HTTP/proxyserver.paragould.psd@xxxxxxxxxxxxxxxxxxxx
How did you create the entry and keytab ?
