I have been endlessly searching for what went wrong, and can't figure it out. There is a lot that I still don't understand about working with samba on Ubuntu, so if something looks noobish, I am sorry.

Before I updated my ubuntu server, sharing was acting normal and the teacher account was able to authenticate, when I updated though, it stopped working.

I'm using Ubuntu server:
Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily

and samba: Version 4.1.17-Ubuntu

When I try to map a network drive from a windows computer (windows 10 in this case, also used windows 7 with similar results), i get the following log results in /var/logs/samba/log.(ip address of windows) :

check_ntlm_password:  Authentication for user [teacher] -> [teacher] FAILED with error NT_STATUS_NO_SUCH_USER

[2016/01/06 14:00:51.944975,  3] ../source3/auth/auth_util.c:1593(do_map_to_guest_server_info)

  No such user teacher [HeritageFileServer] - using guest account

From the windows machine I am logging in as HeritageFileServerteacher, i also tried HERITAGEFILESERVERteacher, and just teacher, in the past, the first one worked just fine.

If I type sudo pdbedit -L -v, which as I understand, is supposed to list my samba users, I get this:

Obviously teacher exists, and the password is very simple, so I'm certain i'm not getting it wrong, I even reset the password to make sure by using smbpasswd.

I ended up setting the important folders to allow guest accounts so the teachers could access the drive, meanwhile I'm trying to get the log to show that it successfully authenticated. Here is my smb.conf file (I have share and Share as the original folders that are now open to guests, while Shared is my test folder that I am trying to get to work with authentication):

Anybody know what is wrong?

Open a terminal and try this:

sudo smbpasswd -a < username>

Here, < username> is your username. Now, you will be prompted to set and retype new password.

Then, restart the smb service:

sudo service smbd restart

Now, try to open the shared location the usual way. Type the username and the new password you have just set.

You should be able to log in now.
