--- Comment #1 from Snorre Jensen sno...@jens1.no 2010-05-12 12:09:00 ---
edited /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
and replaced configure_x section with this:
configure_x() {
if boolean_is_true $CONFIGURE_X ; then
${CONFIGURE_X_COMMAND:-/usr/share/ltsp/configure-x.sh}
else
if [ -n ${X_CONF} ] [ -f ${X_CONF} ]; then
echo Using customized xorg.conf
cp -v ${X_CONF} /etc/X11/xorg.conf
fi
fi
}
and now its working as expected :)
I don't know if it is the right way to fix this, but its working

Now the joke comes: using the thinclient as a diskless workstation makes the java app run perfectly smooth, but because it's a real thinclient and hence low on performance, the boot process took very long, apps took very long to show up, and playing youtube didn't nearly work fluently. Most likely this is related to use (or not) of shared memory (MIT-SHM). As an example, Direct Rendering Interface (DRI) requires shared memory as I understand it. Diskless clients by design do not share memory. I suspect that you might get comparable speeds on lowfat clients even with locally executed applications, if you can tell them to disable use of MIT-SHM. For GTK applications like the Gimp you will pass the option --no-shm. There are probably similar options for Qt-based applications. Now you got me confused. Or maybe I got you confused first.

password synchronization

Yes i'am the one finishing the package in Debian 3.0 format, with all the latest change and triggers ;-) Will be ready for end of the week, or maybe sooner ... depending on my head and 3.0 version packaging ;-) Benoit, to test gosa some more, we need the package(s) in the debian repository. I committed most (some polishing might be needed) that is needed to use gosa in debian-edu-squeeze to debian-edu-config. As soon as the gosa package is available in testing people can start to have a closer look and test, criticize and flame or celebrate and give their ok to keep going on in that direction. Great will hurry to finish it. Can you give an estimate how long this may take? (We could start with something in experimental too if that helps. Perhaps it makes sense to have even non-perfect packages in the repositories anyway, to test some more and fix remaining bugs in the meantime). I promise i will be finished and ready to upload no later than friday That sounds all great! Many thanks in advance. I am looking forward to include and test your work. :) Best regards, Andi -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

We haven't looked into getting it in mainline or in OpenLDAP yet as we are still testing it. There have been some issues in multi-realm kdc/kadmin setups, but those should be fixed now in the Launchpad version. We should get out tools to setup ldap+kerberos and manage users with the overlay really soon now. I hope to be able to think about packaging after that.

Mundt: As of today, compile debian-edu-config from svn and install it. Does this changes popup on the DVD cd-edu-testing-nolocal-dvd/debian-edu-amd64-i386-DVD-1.iso in the next days? First, a new debian-edu-config package has to be built and after that it takes about 10 days until it will be available in testing and on the dvd. I suggest to wait at least until we have gosa available (promised to happen this weekend, so 10 days later it'll be in testing). Currently I work on the integration of kerberos too. So far, I have prepared the script to create principals and the homedirs whenever a user is created in gosa (postcreate hook): That works fine :). For password synchronization some more work/ideas are needed; I'll probably send a draft of the script to discuss that later. I have also a nearly ready script to integrate the kdc-setup in the installation, see here, 'will commit the latest version later: http://svn.debian.org/wsvn/debian-edu/trunk/src/debian-edu-config/share/debian-edu-config/tools/kerberos-kdc-init?sc=1 The only thing missing is some password stuff (you need to enter the root password for the kerberos master key which is not(?) available during installation). For now, perhaps first use that script from the command line after installation and then integrate it. So, all in all anything works in principle, (I already created a user in gosa, homedir and principle were created automatically; and I logged out and in again with the new user using kerberos). To have all that out of the the box, it'll probably take one more fixing round ;-). So to answer your question: As soon as I see a chance that most stuff works and is committed to svn, I'll ask Holger or Petter to upload a new package if that does not happen earlier anyway. Don't want to promise anything, but it looks very promising at least to me! Regards, Andi -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

ldap/gosa postcreation and kerberos password synchronization
Hi all, [first, congrats to the gosa-guys for their latest release ;-)] I am currently thinking about how to handle the post-creation, post-password-change and related stuff properly. So far, I use the draft-script attached below which is run by the gosa postcreation hook (www-data added to sudoers file) to handle all needs: 1.: A (posix) user is created in gosa: The script called as /usr/bin/sudo /usr/sbin/gosa-pp %uid creates homedir and corresponding principal with random password. This works fine. 2.: Now, the password for the new user is entered in gosa. I figured out that the passwordHook=/usr/bin/sudo /usr/sbin/gosa-pp is called with just the password as argument. Unfortunately there is no uid attached, so I do not know how to set the attached password for the user just(?) created. (Currently, the script tries to create a homedir for a user with uid=password, so this has to be fixed too.) 3.: Assume, the user changes his password in gosa now. In this case gosa-pp is called as: gosa-pp uid oldpw newpw As you see below, with root's almighty power the new password is enforced, but there is no check if the old password is known by the executing party. Issue 3 can probably be solved by executing the change as the principal the password corresponds to. But what about issue 2? Are there any better solutions, hints and tips around? Thanks in advance, Andi Here's most of the gosa-pp script: #!/bin/sh [...] NUMARGS=$# PREFIX=/skole HOSTNAME=$(hostname -s) LDAPHOST=ldap BASE=dc=skole,dc=skolelinux,dc=no USERID=$1 case $NUMARGS in 1) ## lookup user and create home directory and principal: ldapsearch -xLLL -h $LDAPHOST ((uid=$USERID)(objectClass=posixAccount)) \ cn homeDirectory gidNumber 2/dev/null | \ while read KEY VALUE ; do case $KEY in dn:) USERNAME= ; HOMEDIR= ; GROUPID= ; USERDN=dn=$VALUE ;; cn:) USERNAME=$VALUE ;; homeDirectory:) HOMEDIR=$VALUE ;; gidNumber:) GROUPID=$VALUE ;; ) test $HOMEDIR || continue echo $HOMEDIR | grep -q ^$PREFIX/$HOSTNAME || continue test -e $HOMEDIR continue cp -r /etc/skel $HOMEDIR chown -R $USERID:$GROUPID $HOMEDIR kadmin.local -q add_principal -randkey -x $USERDN $USERID logger -p notice Home directory \'$HOMEDIR\' and principal \'$USERID\' created. ## send a welcome-email: cat EOF | /usr/lib/sendmail $USERID Subject: Welcome to the mail-system [...] EOF ;; esac done ;; 3) USERDN=`ldapsearch -xLLL -h ldap ((uid=$USERID)(objectClass=posixAccount)) dn | sed s/: /=/` OLDPW=$2 NEWPW=$3 ## FIXME: make sure that $OLDPW is correct kadmin.local -q change_password -pw $NEWPW $USERID 1/dev/null logger -p notice Password for \'$USERID\' changed. ;; *) logger -p warning Invalid number of arguments for $0. esac exit 0 -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.
