Re: [K12OSN] RE: K12ltsp login

I did remove the no_root_squash option from my /etc/exports file and restarted the nfs daemons (portmap, nfs-common and nfs-kernel-server in that order). Just to be sure, I restarted the k12ltsp server, and I get the same results - i.e.- after I enter my user name and password the login screen goes blank and eventually returns to the login screen again asking for my username. ???

So I've conquered the .dmrc problem, got the ltsp box (apparently) talking to the ldap server, successfully remote mounting users /home directories via nfs and yet I still cannot login.

Does anyone have any further ideas on how to make this work? I'm still thinking along the lines of somehow tracking the authentication requests to the ldap server to see if I am getting that far. And if I am, how are those requests being handled by the ldap server?

I'm starting to get anxious about the amount of troubles I am having getting this to work. Perhaps last weeks posts re: the complexity of linux and ltsp REALLY are worth paying some attention to...

Thanks in advance for any help!!

Thanks Rob, that fixed it! Unfortunately it brought up another problem: now my login screen goes blank after I enter my username and password and eventually returns to start all over again, i.e.- asking for username and password. Any help would be greatly appreciated. Thanks,

I don't know why that would happen, but...

If you have completed all the permissions/ownership changes that you think you need, and you don't need to create users' home directories on login, then you may no longer need the "no_root_squash" option.  I don't think that option is required for "normal" LTSP usage.  Try removing that option and restarting the nfs server, then see if your server behaves normally.   Note that in the future instead of setting the "no_root_squash" option to change permissions on the nfs mounted files, you could ssh into the nfs server as root and change them there.
