Battling to load the password backend

Using opensuse 15.6 Leap
samba version
4.19.8+git.422.34307c5a3aa-150600.3.15.1

ls /usr/lib64/samba/pdb/ -lh
total 228K
-rwxr-xr-x 1 root root 142K May 5 08:09 ldapsam.so
-rwxr-xr-x 1 root root 42K May 5 08:09 smbpasswd.so
-rwxr-xr-x 1 root root 38K May 5 08:09 tdbsam.so

the smb.conf has the line
passdb backend = tdbsam

sudo pdbedit -L
[sudo] password for root:
added interface br0 ip=192.168.0.9 bcast=192.168.0.255 netmask=255.255.255.0
No builtin backend found, trying to load plugin

Does /var/lib/samba/private/passdb.tdb exist?

Can you read from the database ok by checking an existing samba user?
sudo pdbedit -v <username>
Or does that generate errors?

What happens if you try adding a samba user with
sudo smbpasswd -a <username>

sudo smbpasswd -a smart

Please share the current working “[global]” section of smb.conf…
sed -n '/^\[global\]/,/^\[/{p}' /etc/samba/smb.conf
Note my use of formatted text. Please do the same when posting commands and output (refer to the </> button in the forum editor).

Also:

5

Run strace…
sudo strace -e openat pdbedit -v smart 2>&1 | grep tdbsam

[global]
workgroup = WORKGROUP
passdb backend = tdbsam
usershare allow guests = yes
printing = cups
printcap name = cups
printcap cache time = 750
cups options = raw
map to guest = Bad User
logon path = \%L\profiles.msprofile
logon home = \%L%U.9xprofile
logon drive = P:
force user = smart
netbios name = SERVER
os level = 33
name resolve order = bcast host lmhosts wins
wins support = Yes
ntlm auth = yes
public = yes
unix password sync = Yes
server min protocol = SMB2_10
obey pam restrictions = yes
pam password change = yes
usershare owner only = false
usershare path = /var/lib/samba/usershares

If I use this below as a share folder, I cannot add filename and folder.
[tmp]
write list = smart,ashleigh
valid users = smart,ashleigh
path = /home/smart/tmp
inherit acls = Yes

With the share folder below I can add and delete / create file.
But when I open a document, it goes into read-only mode.
[Listings]
path = /home/smart/Windows/Listings
force create mode = 777
create mode = 777
force directory mode = 777
write list = smart,ashleigh
valid users = smart,ashleigh
directory mode = 777
inherit acls = Yes

7

…and the strace command?

8

openat(AT_FDCWD, “/usr/lib64/samba/pdb/tdbsam.so”, O_RDONLY|O_CLOEXEC) = 3

9

Ok, that checks out as expected. The installed samba packages are consistent?
zypper se -si samba

Please post the output as preformatted text as already requested. Go back and read my post about that.

Ok so I decided to find a newer version of Samba. Now it looks like it’s working. Not giving me read-only in opening a document.
