| 22:09 | <MRH2> hi i am trying out mint 18 with ltsp pnp and am running in to 2 issues
| |
| 22:09 | I can;t seem to login from a locked screen (there is login prompt but password is not accepted)
| |
| 22:09 | after resuming from suspend there is no login prompt
| |
| 22:10 | has anyone else experienced similar?
| |
| 22:10 | <quinox> it tries to unlock using auth on the client itself
| |
| 22:10 | we use LDAP, screensavers work properly when the clients also authenticate there
| |
| 22:11 | I've never tried resume
| |
| 22:11 | <MRH2> i figured the users and hashed passes were part of the img
| |
| 22:11 | and it would read those
| |
| 22:11 | ?
| |
| 22:11 | <quinox> when you login on an LTSP client it actually attempts to login on the server
| |
| 22:11 | <MRH2> yes
| |
| 22:12 | <quinox> you might be able to copy the hashed passes but it would get out-of-sync as soon as someone changes their password
| |
| 22:13 | might not be a big problem
| |
| 22:14 | <MRH2> ok so the hashed passes aren;t part of the generated image?
| |
| 22:14 | <quinox> nope, not by default AFAIK
| |
| 22:15 | <vagrantc> there is LDM_HASH_PASSWORD feature which works around the problem
| |
| 22:15 | er, LDM_PASSWORD_HASH
| |
| 22:16 | <MRH2> could i mount the directory via sshfs?
| |
| 22:16 | <vagrantc> what directory?
| |
| 22:17 | resuming from suspend ... i'm amazed that works at all
| |
| 22:18 | the best workaround we currently have for allowing local authentication is LDM_PASSWORD_HASH, or setting up proper LDAP or other remote authentication
| |
| 22:18 | <MRH2> i was thinking of a cut down version of /etc
| |
| 22:19 | <vagrantc> why not use LDM_PASSWORD_HASH=true in lts.conf, rather than committing to write code that doesn't exist
| |
| 22:19 | <MRH2> i'll have a look at LDM_PASSWORD_HASH
| |
| 22:19 | <vagrantc> should be supported in ldm 2.2.14
| |
| 22:19 | <MRH2> ok
| |
| 22:19 | trying it now
| |
| 22:19 | <vagrantc> no idea how well supported mint is at this point
| |
| 22:20 | <MRH2> does that mean i need to generate a new img for every new user?
| |
| 22:20 | <vagrantc> no
| |
| 22:21 | it hashes the password at login time and stores it on the client
| |
| 22:22 | basically, LDM logs into the server with ssh using the password provided by the user, mounts the homedir via sshfs, and starts a local session
| |
| 22:22 | with LDM_PASSWORD_HASH=true, it also hashes the password locally so that local authentication works
| |
| 22:23 | it doesn't allow changing the password from the running session though, as that doesn't propegate to the server.
| |
| 22:23 | (well, technically it allows it, but will not be preserved across reboots

| 22:55 | <MRH2> that's ok about not changing passwords
| |
| 22:56 | still testing
| |
| 22:56 | thanks
| |
| 22:56 | i'll try a reset
