Hi there

I need help in order to get PKINIT working on Fedora 14.
I have a running kerberos server with krb-server, krb-server-ldap and so 
on (1.8.2).
I also have installed krb5-pkinit-openssl.

The stuff works like a charm when running in "standard" kerberos, i.e. 
w/o pkinit.

Then we tried to set up pkinit according to the instructions found at 
http://k5wiki.kerberos.org. In particular, we checked carefully, our certs.

However, the behaviour does not seem correct.

We issue a kinit -X x509_user_identity=<DN found in the client cert> 
<principal> on the client side (another Fedora instance with software 
certs).
With Wireshark, we see that an AS-REQ is sent to the server. However, it 
does not seem to convey any certificate (pa-data type = 149).

Then the server replies with ERR_PREAUTH_REQUIRED (the principal that is 
used has its preauth option set).  Is this normal ?

As a result of this, the standard AS_REQ/REP procedure seems to be 
played (as a password is requested on the client side).

The problem is that even when recompiling pkinit with DEBUG set, we 
cannot see anything....

Any help (very) greatly appreciated.

Thanks
Pascal
