Default f16 beta: kerberos credentials expired

Hi,

F16 beta, whenever I log in, tells me "Network credentials have
expired" or, as the message puts it, "Your Kerberos credentails have
expired." (sic). I didn't know I had any up to this point. Choosing
list tickets in the notification shows I don't have any tickets,
choosing get ticket brings up an error message saying "Kerberos
Authentication Error" and "Couldn't acquire kerberos ticket: Cannot
resolve network address for KDC in realm "EXAMPLE.COM"'."

Does anyone know why this might happen?

Thanks

It is happening because of one of two things. Either the
krb5-auth-dialog is broken and isn't recognizing that krb5_cc for the
user doesn't exist, and that it shouldn't complain, OR it isn't started
with -a (that is LOWERCASE -a) which will cause it to not start if you
have no valid credentials.

It appears that whoever set it up in Fedora15/16 (I just upgraded from
14) has it as -A and not -a. I use kerberos so, it really doesn't affect
me. You may want to file a bug.
