Hi guys,
Kevin:
As stated in my first email, the linux box is running on a 2.6.35
kernel, heimdal 1.3.3-1 (the version was not mentioned in my email),
As Kevin says, it would be worth trying MIT kerberos instead of heimdal
if you can, as that is generally better tested.
--b.
rpcbind-0.2.0-2, nfs-utils-1.2.2-3, and the distro is arch-linux.
Bruce: I would rather find an "easier" (configuration-specific) way
to overcome my problem instead of delving into the code, since I am
not a developer (I am an admin :)). Nevertheless, when I used
google.com/searchcode for _gss_get_mechanism_cred I found that there
is a libgss/g_glue.c that defines this function in the following way
(the site is svn://svn.genunix.org/on/trunk<http://google.com/codesearch/p?hl=en#m0BoFGhUuEY/&q=_gss_get_mechanism_cred>):
/*
* Glue routine for returning the mechanism-specific credential from a
* external union credential.
*/
gss_cred_id_t
__gss_get_mechanism_cred(union_cred, mech_type)
const gss_union_cred_t union_cred;
const gss_OID mech_type;
{
int i;
if (union_cred == (gss_union_cred_t)GSS_C_NO_CREDENTIAL)
return (GSS_C_NO_CREDENTIAL);
for (i =0; i< union_cred->count; i++) {
if (g_OID_equal(mech_type,&union_cred->mechs_array[i]))
return (union_cred->cred_array[i]);
}
return (GSS_C_NO_CREDENTIAL);
}
where you can see that the guy returns a cred_array[i] element, that
obviously is null, because (most probably) the if statement above
did not match any "compatible" mechanisms during the recursion.
Maybe I am totally wrong, since I haven't checked the code
thoroughly, but I think that the problem is located somewhere in
this code segment.
As I stated before, I was rather hoping to avoid this procedure,
since I decided to use the linux distro for my clients due to its
'out-of-the-box' and 'everything-is-supported' benefits as
(slightly-)opposed to fbsd (which I use in all my servers and
personal computers, and "love" as an operating system) can be a bit
more "demanding" when out-of-the-box-general-purpose issues are
involved. The thing is that the client will be used as a
general-purpose student pc in a university lab.
Thanx again for your help,
if anybody could direct me somewhere else I would be delighted to know so!

Ok Bruce and Kevin,
I'll try and do that. I only hope that MIT-client is compatible with
Heimdal-server (if I manage to install it on archlinux through AUR...:)).
