If I replace the pam_stack.so entries in /etc/pam.d/kde with the entries in /etc/pam.d/system-auth, it works without any delay. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Use the kdm login manager 2. Type in the username 3. Experience the delay before being allowed to enter the password Actual Results: A delay of 3-4 seconds even on my quickest machines Expected Results: No delay Additional info:
Does kdm still exhibit the same problem if you replace its PAM configuration with the one used by gdm, or xdm? If it does, then I'm suspecting it's a kdm bug.
Yes, kdm still exhibits the same problem if I replace kde with gdm in /etc/pam.d. They were the same except for a tab on the last line.
Created attachment 50344 [details] kgreeter patch that doesn't check for empty password
In talking with the KDE guys, they figured out the problem. It seems that when using the [Enter] key, it would try the username with a blank password. If that didn't work, it would go to the password entry. Using [Tab] would alleviate the timeout. The fix was a patch to kgreeter.cpp commenting out one line. They have entered it into CVS.
There may be more to this problem than what was found by the KDE folks. I find that the delay is associated with the display of the Red Hat logo. In my case I'm connecting via XDMCP. When the login screen first comes up there is no logo. If I type in my username and then try to tab to the password field, the focus remains stuck in the username field *until* the Red Hat logo finally gets around to being display. Then focus moves to the password field and I can proceed normally. If I wait for the Red Hat logo go come up before I even start typing my username, then there is no delay between the username field and the password field.
This has been fixed for a while...
