Hi Christopher,

No reason really, just using DES keys for testing.  Once I get this 
working I'll move up to better encryption.

Changed the values on all that stuff, I guess I'm just paranoid....  :)

Everything on the Solaris box is in /etc/krb5/.

I can kinit OK.  I get a ticket successfully.

I can do this:

kinit -kt /etc/krb5/krb5.keytab nfs/
kinit -kt /etc/krb5/krb5.keytab host/

with no errors.   When I do a klist then I get:

Ticket cache: FILE:/tmp/krb5cc_0
Default principal: host/ at MYREALM.COM
Valid starting                Expires                Service principal
06/19/06 11:21:20  06/20/06 11:21:20  krbtgt/MYREALM.COM at MYREALM.COM
         renew until 06/19/06 11:21:20

Does this mean that things *should* be working, but they aren't?  That's 
scary...  :(  I tried kinit'ing as nfs/ and then 
tried to mount but got the same error in the logs...

Thanks for replying by the way!

ciao, erich
