I have KDE installed in my archLinux with kdm to login. But it always shows a notification dialog with "authentication failed" about every 2 minutes.

I use a kdm to login and I have enter the user name and password. Why does it show "authentication failed"?

Anyone who encountered this problem can help me?

Finally this problem disppear because I reinstall kde.Thanks for all of you!

Are you sure the issue is with KDM, and not with a Telepathy account, KMail or a similar application? (since you can actually log into the session, else you would not see the notifications I presume) –  Gallaecio Nov 10 '12 at 17:25
    
I'm sure the issue is with KDM because I made it run as a daemon. –  itlodge Nov 11 '12 at 10:43

This is indeed very annoying. In my case on Fedora 19, the culprit was PackageKit. Apparently if you mistype the root password once, PackageKit will forever bother you with anonymous "Authentication Failed" popup messages.

Removing packagekit is a brute force solution:

sudo yum remove packagekit

You will need to manually update your system with your package manager, e.g. yum.
