2.2alpha3 with TDB support

   I'm currently testing Samba-2.2.0-alpha3 with TDB support. However,
with "security=user", I cannot add users to the smbpasswd database
using the command ``smbpassd -a -D10 alice alice'' as root.

   Without TDB support, Samba seems to work fine. This problem occurs
on both Digital Unix 4.0g and Linux 2.2. Anyway, the output of
smbpasswd when tdb support is builtin.

[root samba]# ./smbpasswd -a -D 10 alice alice
getpwnam(alice) called
Unable to open TDB passwd!Unable to open TDB passwd!endtdbpwent: closed password file.
Failed to add entry for user alice.
Failed to modify password entry for user alice

   I have not done anything (after ``make install'') to generate a
basic smbpasswd file. In addition, smbd and nmbd are NOT running. If I
have skipped a crucial step, then could someone tell me please. The exact 
same steps without TDB support works. I can provide my smb.conf file if

   Finally, I have a few questions about TDB in general.
1) Are there any docs regarding TDB which I can read other than source?

2) With TDB, the smbpasswd encrypted password file keeps the same
filename, but the format changes from a text-file to a binary tdb file.
Is this correct?

3) The smbpasswd scripts (eg addtosmbpass, convert_smbpasswd,
mksmbpasswd.sh) are useless for Samba with TDB support -- right?

4) Samba with TDB should scale better as the number of users increase
as everytime Samba forks, it doesn't have to read the whole TDB file
(say 5MB). Instead, it can jump directly to the user record.

5) What is the state of the TDB code in general? Is it "known to be
broken", "should work perfectly" or somewhere in between?

   On a different (minor) topic, I've noticed the following warning 
messages when compiling samba-2.2.0-alpha3 under Linux 2.2 with

the use of `mktemp' is dangerous, better use `mkstemp'

PS Yes, I am aware it's development code and that it may not work. I'm
also willing to do a bit of work, if only I knew what to do. However, I
read the message from Jeremy that Samba was being readied for release.
