Excuse me dear Douglas ,
but I'm French and my english sucks a little bit .
*) The machine is a windows XP Pro box.
Already belonging to a domain.
the ": (not that the computer pre-exist in"
Was a misspell of " (note that the computer pre-exist..."
*) The machine name is WWWSRVHOST which is ALSO is Host name under windows
as far as I know ? because on the Win2003 box it shows these spn : HOST/
WWWSRVHOST.... like this BEFORE any of our changes .
*)The AD Domain name on site was CCIAL.local (that is the way windows2003
spells a simple domain name.)
For trying to not pollute the case I tried to say it is just a FQDN (fully
qualified domain name) because if this is a trouble I will make them change
So excuse me for the misspelling between FQDN and FDN.
Next time I will take more time to re-read my post. Specially in a foreign
All this was to try not to give you too much annoying details which will
make you lose your time.
my app is a custom app with webserver (NO IIS) and provides some SSO
facilities via Java and SPNEGO. That's why I have to do all this stuff :
to get the keytab of the XP computer which hosts my web app.
This is needed for the SSO to work.
The web server uses some Java 6 techs including the JAAS layer for security
which is the one that allows the Kerberos token handshaking.
I talked about cygwin just because it seems mskutil works only under unix.
They don't have a "real" DNS as they are a simple organization ; just
windows boxes. So DNS setting is not a real problem here.

I hope I'm little bit more clear now ?!
( * ) ( * ) ( * )
My job is to give this infamous keytab for the app.
And for this to work in sun tutorials they ask for the keytab of the
computer hosting the webserver.
Now I must confess I'm lost :
It seems you are telling me I should make another spn's keytab but not the
machine's one ? I don't know how all this will work then as Sun was asking
for the machine's keytab.
I'm not at the office to try all these
Will be there only tomorrow afternoon or Monday.
Thank you for your time and your help.

(Some of you examples use FQDN, some FDN. You refer to the machine
as WWWSRVHOST but it also has a DNS hostname. You attempts
at obfuscating the information in the e-mail is making
it hard to understand your situation.
First of all, is the computer WWWSRVHOST a Windows machine?
Is WWWSRVHOST the name?
What is its DNS name?
Is it joined to the domain?
What is the AD domain name?
And you want to run a web server on it?
If this is all Microsoft servers and web servers, you should not
have to create any keytabs. It should be done for you.
Are trying to run some web server under cygwin?
If so use two seperate windows accounts, one for the host service
handled by windows join, and one for the HTTP service,
and use ktpass. (This keeps them seperate, and avoids the common
The account name does not have to be the spn.

No there is no. You should not need this with windows.

You said the computer was joined. Now you say it is no.
