I'm running FreeBSD 6.1-RELEASE and installed samba-3.0.22,1

Here is the global section of my /usr/local/etc/smb.conf:

[global]
workgroup = OFFICE
server string = Samba Server
passdb backend = tdbsam
logon script = scripts\logon.bat
logon path = \\%L\Profiles\%U
logon drive = H:
logon home = \\%L\%U
domain logons = Yes
os level = 35
preferred master = Yes
domain master = Yes

After a fresh install of samba smbpasswd gives this:
[root@aldebaran ~]# smbpasswd -a admin
New SMB password:
Retype new SMB password:
Unable to open/create TDB passwd
Unable to open/create TDB passwd
pdb_getsampwnam: TDB passwd (/usr/local/private/passdb.tdb) did not
exist. File successfully created.
Segmentation fault: 11 (core dumped)

Then it gives this:
[root@aldebaran ~]# smbpasswd -a admin
New SMB password:
Retype new SMB password:

TDBSAM version too old (0), trying to convert it.
TDBSAM converted successfully.
Added user admin.

After that, samba seems to work properly.

If I touch /usr/local/private/passdb.tdb after a fresh install of samba
I have directly the second behavior (no segfault) and then again samba
is operational.

What did I miss?

You possibly found a bug in the port. Contact the maintainer or file a pr.

HTH,

Thanks. I did contact the maintainer.

I tried with FreeBSD 6.0-RELEASE and samba-3.0.14a_1,1 from the ToolKit disk.
When I first use smbpasswd I only have the account_policy_get failures
(no segfault).

BTW I searched the web about the account_policy_get failures but couldn't
find any explanation exept that it is safe to ignore those messages when
smbpasswd is used for the first time.
Can someone shed some light on them?

Regards,
Thierry.


My guess, without looking at the source code, is that smbpasswd tries to access passwddb.tbd before adding the first password. Since the file is empty, it's an invalid file and generates errors.

HTH,
Micah
