I have the same issue trying to login locally using xdmcp and Xephyr.

Same issue.  Can not login with Kdm via a remote screen.  Kdm seems to be
failing with a memory problem, but only on a remote connection.  Local seems to
work corretly

We had this same problem, and copying kdm from fc6 fixed it.  This machine was
originally an FC6, and got upgraded to FC7.  Remoted logins have been working
fine until today, so perhaps it was some recent updates?

appears to be induced by ICEauthority patch, see bug #247455

kdelibs-3.5.7-9.fc7 has been pushed to the Fedora 7 testing repository.  If problems still persist, please make note of it in this bug report.

kdelibs-3.5.7-9.fc7 has been pushed to the Fedora 7 stable repository.  If problems still persist, please make note of it in this bug report.

Even after bug #247455 was fixed, I can still reproduce this, at least using
vnc-server and/or vnc-ltsp-config.  I get a login screen, but after providing
username/password, the vnc session dies. ??

unsuccessful kdm login

this partial log file has two attempts to login using kdm.
local login - a successful one (10:29)
remote xdmcp - an unsuccessful one (10:49)

updating:
kde-settings (3.5-29.fc7) to 3.5-30.fc7
kde-settings-kdm (3.5-29.fc7) to 3.5-30.fc7

didn't solve this issue.

please tell me if i can help in any way !

is this solved ?

it holds us from upgrading 10 servers that work as terminal servers.
if you need any help, please tell me what to do :-) 

this seems related to the ConsoleKit patch, i rebuilded my kde without this
patch and all work without any problems.

Can someone confirm this ?

what are the packages i need to download and install to confirm this ?

sorry i may be wrong but download
ftp://download.fedora.redhat.com/pub/fedora/linux/development/source/SRPMS/kdebase-3.5.8-5.fc8.src.rpm

install it, comment the line %{?_with_hal:%patch27 -p1 -b .consolekit}

and launch the build using:

rpm -ba kdebase.spec

soory but this is only if you have kde 3.5.8
which kde do you have installed ?

we use : kdebase-3.6.7-13  on  fc7

should i upgrade to kde 3.5.8 in rawhide to test this ?
can i just enable the respective repositories and upgrade (kde) ?

maybe just get the kdebase 3.5.8 from rawhide ? is it enough ?

(i have a testing server, so i don't mind messing it up)

:-)

it would be better to keep the same Kde to have a point of comparison :)
i can't find a source rpm for your version.

Can someone point where to find it ? 


thanks

I can do a scratch build with the patch disabled for testing purposes.

rex : please :-)

rex: which build kdebase in koji should i try ?

no news, no scratch build exists, yet.  

I think it's a given that consolekit integration is to blame here.  Omitting
consolekit support isn't an option, so what really is needed is to debug what's
going wrong and simply fix it.  Help, advice, assistance welcome.

I have been through the following routine just for confirmation on fully
updated Fedora 8 on x86-64
rpm -i kdebase-3.5.8-5.fc8.src.rpm
cd ~/rpmbuild/SPECS
Edit out two lines ref to consolekit in kdebase.spec
export QA_RPATHS=$[ 0x0001|0x0010 ]        This was needed for rpmbuild to work
rpmbuild -bb kdebase.spec
Extracted only kdm from resultant rpm
X and Xephyr will now login successfully - Sound errors given though,maybe more
Xnest works as above but has additional problems
Had a look at kdebase-3.5.8-consolekit-kdm.patch
It meant zero to me I'm afraid !!
What happens next?

Apparently Mandriva issued a fix for this on November 14:
http://www.mandriva.com/en/security/advisories?name=MDKA-2007:110
http://qa.mandriva.com/show_bug.cgi?id=34786
Now we just need to snatch their fixed patch.

Found the diffs, will fix ASAP.

Arg, all this silliness with distros keeping separate patches... 

My Christmas wish, let the ConsoleKit patch/support get accepted upstream,
please please, pretty please:
http://bugs.kde.org/147790

Perhaps our Mandrake friends could help with the upstream integration too...
hint hint. :)

Perhaps our (oops, edited) Mandriva friends could help with the upstream
integration too... hint hint. :)

adapted consolekit (from Mandriva)

Here's my quickly munged version of Mandriva's consolekit patch that applies
against kdebase-3.5.8 (I'm doing some local mock builds now for testing).

Patch confirmed mm-mm-good.  Now to kick off a some test builds.

update candidate builds pending:
F-7: http://koji.fedoraproject.org/koji/taskinfo?taskID=264431
F-8: http://koji.fedoraproject.org/koji/taskinfo?taskID=264441

I'm pretty sure these should address our problems here, but if anyone else could
confirm it for us, that would be great.

I looked at the diff of the diff ;-) from the CVS commit message and it looks 
OK (it has the 2 changes from Mandriva). Thanks for having taken care of this. 
(I would have done it today otherwise.)

We need to update the KDE 4 version of the patch too, for kdebase-workspace, 
though.
