[Ltsp-discuss] cannot build fat client image on Ubuntu16.04

Discussion:

The LTSP server uses ldap,
the LTSP client uses ssh to authenticate to the LTSP server,
so the LTSP client uses ldap indirectly, not directly.

So, remove all the ldap bits from the chroot and try again.

Dear Alkis Georgopoulos,
Thanks for your advice!
I reinstalled all and have same trouble yet.
Installed Ubuntu Desktop 16.04 on XenServer7.0
-LTSP server
Installed ldap and set up to LTSP server
Installed ltsp-server
-not ltsp-server-standalone
Executed ltsp-build-client
-use /etc/ltsp/ltsp-build-client.conf to make fat client
The client can boot up and greeter (?) is displayed.
A local user can log in.
A ldap user cannot log in.

Sounds like either a misconfiguration or a bug, it's supposed to work
out of the box.
Unfortunately it would take too long to troubleshoot this over a mailing
list, maybe someone else could help...

Thanks for reply.

There are people who was able to install and use LTSP on Ubuntu 16.04, so I
think I miss a configuration...

Now I refer the following URL.

https://help.ubuntu.com/community/UbuntuLTSP

This site includes the information for various version. Are there better
site?

And, I am sorry for wrong mail title...

Are you able to login with ssh to the server using ldap credentials from a
regular Linux host? I suspect missing/incorrect config on the server.

Dear all,
I constructed fat client on Ubuntu Desktop 16.04 which is on XenServer 7.0.
Now a local user can log in, but a user registerd on ldap can not log in
the fat client.
I can find the message "Permission denied(Publickey, password)".
After log in by local user, I can switch ldap user by su - [ldap user
name].
And id [ldap user name], getent passwd and get ent shadow seems to work
properly.
-Install ltsp-server
I have already DHCP server so I did not chose ltsp-server-standalone.
-build-fat-client
-Install ldap client and nscd to fat client
-basic setting and rewrite nsswitch.conf and pam.d/common-passwd
I really need your help.

Yes, I can login with ssh to LTSP server from other machines, from Linux
and windows.

Dear all,
Thanks for your advice.

Today, I reinstalled Ubuntu Desktop 16.04 and set up ldap carefully and set
up LTSP.
I could construct fat client image and log in ldap users.

Perhaps, my configuration missed.
Thanks for your help heartly.

Hi Kentarou, did you record how you set up the LDAP on your system? I've
used likewise open (now powerbroker open) since 2010 to connect my Ubuntu
LTSP server to our districts AD servers. However, this year when I
attempted to switch from 14.04 to 16.04 I was unable to get AD
authentication to work with powerbroker open in the time available so we
are still using the old 14.04 setup. If you kept notes on how you setup
LDAP on your LTSP server or you have some web page you felt was especially
helpful, please share! Not sure when I will re-try solving this but it will
be good to have this info on record.
Thanks,
David

Hi, David,

I recorded the way to set up ldap. The constitution is asfollows.
-ldap + samba + various server
-samba doea not play role of AD.(I felt the bother to setup kerberos:p)
-I never use powerbroker.

If my setup seems to be useful, I will translate and send with e-mail(my
note is written by japanese)
Perhapse, I can inform the way to setup ldap for samba(PDC?).

Hi,David,
I adds to previous mail.

I used LTSP on ubuntu 14.04 and switched to 16.04.
But ldap server did not change.
I setup LTSP server as normal ldap client.

Can you login LTSP server by ldap user?

Hi Kentarou,

It looks like the setup you describe is pretty different from what I've
been using. Thank you for offering to translate your directions, I won't
ask for that now. In the upcoming summer (june-august) I will try to switch
from 14.04 to 16.04 again, first with powerbroker (maybe I mis-configured
when I set it up) and if that doesn't work I'll explore other methods--and
get on the ltsp-discuss list-serve. So I may ask for your support--and that
translation--then.

Hey Kentarou -- it's fine right now because I'm using my old 14.04 system!
In 6 months or so I will again try to solve the LDAP/AD problem with 16.04.
Thanks and best of luck to you as well!
