1. The password hash looks a bit like a crypt(3) hashing scheme. You shou=
ld=20
consult the crypt(3) man page on this system. There are {crypt} schemes w=
hich=20
uses several rounds.
2. You will find several such password modules in the source distribution=
in=20
directory contrib/slapd-modules/passwd/

(ITS#8115) Adding passwd hash schemes
by bruno_haleblian＠carrefour.com
Full_Name: Bruno HALEBLIAN
Version: 2.4.40 >

URL: https://api.drupal.org/api/drupal/includes!password.inc/function/_passwor...
Submission from: (NULL) (195.154.81.10)
Hi,
My goal is to import millions of accounts from a drupal DB to OpenLDAP.
preserving existing passwords. I plan to write a SQL to ldif script for that.
Problem :
These accounts come with a non-standard passwd hash scheme. I've attached drupal
link to source code in PHP.
Although it uses standard SHA512 and base64, the algo is a variant of multiple
sha512 + salt iterations. Looks like there's no way to convert to {SSHA512} or
something standard.
Supposing I can translate it to C, what is the best and cleanest way to
integrate this specific scheme?
Is there an "overlay way" to do this?
Do I Have to hack into passwd.c in lutils?
Has this kind of work already been done?
Goal : getting userPassword={DRUP7}$S$DNbBTrkalsPChLsqajHUQS18pBBxzSTQW0310SzivTy7HDQ.zgyG
to be supported
Regards,
BHa.

Looks OK. One minor nit - we discourage using strlen() (or most of the
libc str* functions, really). We particularly discourage runtime
calculations on compile-time constants (including string constants) -
use the STRLENOF() macro instead.

Thank you for your advice! I've simplified the patch (url stays the same).

Hello Howard,
Please accept my apologies, the issue was not related to LMDB. There have
been a data race in my code that was only triggered by fast writes.
Sorry for late answer, - your e-mail landed into the spam-folder, and I

Hello there, I have ran into an issue with LMDB, which I can reproduce at w=
ill,<br>
but it seems a specific one. The git commit is<br>
3368d1f5e243225cba4d730fba19ff600798ebe3<br>
And this commit and my issue seems to be related.<br>
<br>
1. I use MDB_NOTLS flag on environment open.<br>
2. if=C2=A0 I use MDB_NOSYNC flag for LMDB environment, the writer thread i=
s stuck<br>
after several transactions (writer thread backtrace):<br>

If you're having this problem in 0.9.14 then it is certainly not relate=
d to 3368d1f5e243225cba4d730fba19ff600798ebe3.<br>

You confirm that the issue does not occur in 0.9.13? Can you upload a test =

Hi Jan, there's no need to muck with the list of strings, just use
c->line instead of c->argv.
