I am on Ubuntu Server 20.04, running Samba version 4.11.6-Ubuntu. I need to modify a Samba user account, but I am unable to open sam.ldb due to it apparently not being present. Here is the output:
$ samba-tool user edit username
ltdb: tdb(/var/lib/samba/private/sam.ldb): tdb_open_ex: could not open file /var/lib/samba/private/sam.ldb: No such file or directory

self.connect(url, flags, options)

super(SamDB, self).connect(url=url, flags=flags,
I cannot list users either. I haven't tried any other subcommands yet.
I checked the folder it's referring to. Here are the contents:
$ ls
msg.sock netlogon_creds_cli.tdb passdb.tdb secrets.ldb secrets.tdb
The Samba server is running only as a File Server. I'm not running an LDAP (as far as I know). I installed Samba originally under Ubuntu Server 18.04. Other than adding shares to the .conf file I've never made any modifications to the installation.
