site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Hi list, I'm running a cluster of Mac's with kerberized nfs, and I keep getting this rather cryptic error message in my log: We are running SGE (sun grid engine), and the above error prevents us from writing to nfs directories. So far, our solution is to reboot the machine. I'm wondering if anyone has had similar experiences, and if anyone knows what error code 19777 actually means? Here's an answer from the maintainer: You can read more about kerberized NFS in Leopard here: http://docs.info.apple.com/article.html?artnum=306694 -- Terry _______________________________________________ Do not post admin requests to the list.

The message implies that the kerberos library attempted to pop up a window to obtain a kerberos login because you're lacking a ticket. You'll normally get a kerberos ticket when you log in through the loginwindow or the screen saver. You get the message if you try to access a kerberized NFS mount without a kerberos ticket - in this case it was user 501 - which looks like a local UID - not a network one. You can verify your kerberos creds with the klist command - or attempt to establish one with kinit. This email sent to site_archiver@lists.apple.com
