ppolicy: pardon password history
by hercherf＠hrz.uni-marburg.de 21 Apr '15

21 Apr '15

Hi list, I have made a tiny modification to the ppolicy-module. The aim is to go easy on people who forgot their password, or forgot to deploy their recently changed password to all devices (think of laptops, smartphones, etc.). Whenever a login fails due to a invalid password, the ppolicy-module will count this as a failure. After a configurable number of password failures in a given time, ppolicy will take action and - for example - lock the acount. I have tried to tweak this behaviour: When the password is found in the password history, the ppolicy-module will not count this as a password failure. If anyone is interested in this, please find the attached patch which also includes a working example configuration/testcase. Best regards, Florian -- Florian Hercher | Hochschulrechenzentrum | Philipps-Universität Marburg Hans-Meerwein-Str. 6, 35032 Marburg | fon +49-(0)6421-28-21036

Fwd: [Patch] Allocating sparse files on Windows
by Colin LeMahieu 20 Apr '15

20 Apr '15

Apologies if this arrives twice, I sent it once two days ago before subscribing to the list and it hasn't appeared yet so I'm resending after subscribing. Memory mapping files on Windows requires the file size to match the size of the memory mapped region however in the current implementation this requires creating a file the full size of the environment which may be much larger than the actual amount of data in the database. This patch creates the database as a sparse file on Windows. Windows Explorer will report the file size as the size of the entire memory mapped region but the size on disk will be proportional to the size of committed data in the database. This can be checked by checking the "size on disk" property of the file. Let me know if this is posted incorrectly, otherwise feel free to modify the patch in whatever way is necessary for approval.

www.openldap.org not mobile-friendly
by Hallvard Breien Furuseth 14 Apr '15

It will drop in Google's ratings next week because it fails the <https://www.google.com/webmasters/tools/mobile-friendly/> tests. Maybe someone can fix the web pages up a bit? I'm too busy now. -- Hallvard

Fwd: Using sendfile with lmdb

Eric thank you I would have never considered that as an issue. I tried out your code and saw the problem. You saved me going down a rabbit hole.

Using sendfile with lmdb
by James Rouzier 02 Apr '15

02 Apr '15

Hey Guys, I am working on a proof of concept of a simple key value store service using lmdb as the back end. I am using sendfile to avoid an extra copy. I accomplished this by creating function to extract get the mmap ptr from the env so I can calculate the offset of data. I figured that function might be useful to the bigger community. If it does not fit in the bigger vision of lmdb it is fine not to include it. You will find the diff attached. Thank you James

slaptest-ldif -l <ldif> tool or slapadd option
by Hallvard Breien Furuseth 25 Mar '15

25 Mar '15

I'd like a slap tool which verifies an LDIF before I try to ldapadd/slapadd it. "slapadd -u -o value-check=yes" is fairly close. What does it fail to catch? I can think of: - Duplicate entries. - Missing entries (if the initial DB is expected to be empty). - Child entries before parents (OK for slapadd to at least back-<bdb,hdb,mdb>). - Issues which the tool can only catch if it opens the database, like attempts to add already-existing entries. I probably don't want to do that. - Issues which overlays like slapo-unique would reject. Can't do that, since the overlay won't have a non-empty DB to check against and slap tools do not use overlays anyway. Might special-case "unique" though, since the "duplicate entries" check will need uniqueness code anyway. -- Hallvard
