This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Comment 3 Simo Sorce 2007-03-15 09:38:41 EDT
Do you still have this problem with later releases?
Can you reproduce this at will?
Does it happen only with that client registration (machine named SORIN), or does
it happen for all clients?
Comment 4 Sorin Sbarnea 2007-03-15 09:45:19 EDT
With the latest release I cannot confirm this bug anymore.
Comment 5 Simo Sorce 2007-03-15 12:15:40 EDT
then I close it as fixed with current release, thanks for helping.
