![]() Smb.conf is done before the first login, there will be Win9x access Work with lanman support, so unless a corresponding modification of 3.2.0 also turned off the default for client plaintext auth=.īefore 3.2.0 all three were turned on by default. Samba version 3.2.0 turned off lanman support by default, both on the client ( client lanman auth=) and the server ( lanman auth=).

Interestingly enough, I have a Windows 10 PC at home connected to this domain as well, and I can log on using domain accounts on that one too.For the best books on Troubleshooting, Rapid Learning and Personal Productivity. I'm guessing this is something to do with nssswitch and pam modules, but I can't currently figure out what is misconfigured. Any hints as to what may be wrong here would be greatly appreciated. On member PCs all of these work fine and getent group returns full lists of users. However trying getent passwd MYDOM\\someuser gives me nothing while getent group MYDOM\\somegroup gives me correct info for the said group except it's members - the list is empty. ![]() Using samba-tool to retrieve user info also gives me all information on my users. On the AD DC I can retrieve users using wbinfo -u.

This is so strange because domain member PCs (Ubuntu 20.04 as well) can login using domain accounts without issues, albeit they do so via SSSD and not winbind. And I haven't been able to log on using domain accounts eversince. It did allow me to log on locally but then the server demanded a reboot. In all honesty I can't think of what I broke because it just stopped - my screen got locked through inactivity, and when I tried to unlock it the machine refused my correct password. I use the server which runs this Samba instance as my primary workstation, so I need to be able to log on to it using domain accounts, and up until today I was able to do so. I've been trying to setup Samba AD DC on Ubuntu 20.04 for a good while now and with some success.
