[Ltsp-discuss] LDAP/AD user can log into shell at client but not at the splash screen. Local user, neither.

[David Groos]

Hi again,

After patching (https://bugs.launchpad.net/ltsp/+bug/1610304) as described
in my just-posted forum e-mail, I got some interesting results with the
logins.

1. I applied patch and rebooted the server (though didn't try to update
ltsp image)
2. Booted a fat client, then tried to login w/admin user account, didn't
work.
3. Returned to server, Right-clicked on client "2A" icon in Epoptes
window:
a) execute --> open terminal --> Root, locally.
4. In client "local, root terminal": cat /var/log/auth.log (sorry, can't
copy/paste): Loading Image...
5. Repeated with an LDAP/AD user and got exactly same results (nothing
extra printed to log)
6. At client pressed "Ctrl + Alt + F2" and dropped me into a login shell
7. Tried to login w/the admin account but said, "login incorrect " and
in the log added these 3 lines (also same results for attempt with normal
local user): Loading Image...
8. at client tried to login with LDAP user and it works! log added these
3 lines: Loading Image...

*Summary*: Neither local nor LDAP user can log in at client. When dropping
into shell, however, LDAP user can log in but local can not.

Any ideas?

Thanks,
David

X01-localapps is a client-side script, so if you didn't run
ltsp-update-image, you didn't change anything at all.

Makes sense, thanks again.

Sounding like time to do a fresh install. I poked around in the logs as to
why this happens:

sudo ltsp-update-image --cleanup /
[sudo] password for xyz:
^Crmdir: failed to remove '/tmp/tmp.f6EaWaAzef': No such file or directory

and nothing sticks out.
