I just updated my f15 system to yesterday's updates (08.iii.2011), those including kernel-2.6.38-0.rc8.git0.1.fc15 &c. I rebooted the machine, as I wanted to run the new kernel. When kdm logged me in, I saw 2 keys with a red 'x' in the system tray. Hovering over it shows "Your credentials have expired" and when I clicked it, an empty window appeared, and after a long, long delay, it filled in with the following information: Couldn't acquire kerberos ticket: 'Cannot resolve network address for KDC in realm "EXAMPLE.COM"' What is this and why is it appearing? I don't know what kerberos is and I don't think I have used it in 12 years of linuxing. What do I do about it to fix it? -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
