| 14:10 | <danboid> alkisg, I'm back to investigating why LTSP doesn't like nslcd for LDAP. There are two oddities with LTSP/nslcd. The first is that when I run `su - LDAPUSER` on a LTSP client it logs me straight in instead of asking for a password like I'd expect but
| |
| 14:11 | alkisg, When I run `getent passwd LDAPUSER` on the LTSP client I get incorrect info but the same nslcd config gives me correct info when not using LTSP
| |
| 14:12 | Most notably the UID and GID are incorrect, as is my full user name
| |
| 14:14 | The UID and GID are incorret when I run `getent passwd LDAPUSER` under LTSP+nslcd but they are correct when I run Ubuntu 20.04 + nslcd w/o LTSP
| |
| 14:15 | Could this be because LTSP uses a different PAM library to LTSP?
| |
| 14:16 | nslcd uses a different PAM library vs LTSP?
| |
| 14:16 | alkisg, nsld uses libpam-ldapd

| 14:18 | <danboid> I tried tried on rsyslog debugging for PAM but the rsyslog debug logs were huge and I wasn't finidig anythig to dio with PAM
| |
| 14:19 | plus, they only worked in my VM and not on the LTSP client for some reasin
| |

| 14:20 | <danboid> It seems to me that my nslcd config is fine but its clashing with something in LTSP
| |
| 14:20 | or LTSP expects PAM to be handled differently?
| |
| 14:26 | I don't know if its relevant to LTSP but by browsing packages.ubuntu.com I can see sssd-ldap depends upon sssd-common whic in turn depends upon libpam0g, which is obviously not the same as libpam-ldapd as used by nslcd
| |
| 14:28 | I think most of LTSP is shell scripts so I'm not sure this matters?
| |
| 14:50 | ogra` is now known as ogra | |
| 15:04 | <alkisg> danboid: I think it would be much easier for you to hire someone to solve these issues in a couple of hours instead of trying for weeks :)
| |
| 15:04 | I don't think that issue is related to the LTSP code. No, LTSP doesn't use any different PAM libraries...
| |
| 16:04 | <danboid> I don't want to give up just yet! No-one is shouting at me yet :)
| |
| 16:05 | Looking at /usr/share/pam-configs/ltsp opn the client I can see its using Additional mode without me specifying it ltsp.conf, which is prob what it should be doing
| |
| 16:06 | <alkisg> Additional is correct for your use case, as you don't want LTSP to do the authentication, you just want it to do the sshfs mount
| |
| 17:54 | <danboid> alkisg, /run/ltsp/pam/LDAPUSER/shadow doesn't look right on my LTSP client/ The second field contains pamltsp. I'd expect this field to be a hash of the users password, if its used conventionally
