(ITS#8786) Allow OpenLDAP to start as non-root
by akram.benaissi＠gmail.com 08 Dec '17

08 Dec '17

Full_Name: Akram Ben Aissi Version: 1.1.10 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (77.154.204.242) Hi, We want to run OpenLDAP in containers without root privilege, nor root user id. Actually, we start it with user uid=100000009, gid=0 And we do proper chgrp 0 and chmod 0770 on require directories. Because of this: https://github.com/winlibs/openldap/blob/master/servers/slapd/user.c#L158 we have that: Could not set real user id to 100000009 It would be better to check that setuid is required only if asked user is different from actual user. Does it make sense ?

Can you suggest that how we could implement password quality/strength in this version of openldap. Regards, Sunita Kashyap Manager(Programming) ONGC

(ITS#8784) SIGBUS in mdb_page_touch

Full_Name: Sergey Z Version: LMDB_0.9.19 OS: Android URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (2620:119:5001:2242:9215:2763:ff1b:ae35) Hey guys, We are using LMDB 0.9.19 in our Android project and sometimes we are getting SIGBUS in mdb_page_touch(). We can't reproduce this issue on our side but we have plenty of crash reports from our users (about 400 daily): SIGBUS libLMDBAndroid.so.mdb_page_touch ( mdb .c :2412) libLMDBAndroid.so.mdb_page_search ( mdb .c :5610) libLMDBAndroid.so.mdb_freelist_save ( mdb .c :3128) libLMDBAndroid.so.mdb_txn_commit ( mdb .c :3606) This is probably a platform specific issue because 95% of crashes happened on Android 7.0. I would greatly appreciate if you help to shed a light on this - any ideas what might goes wrong or what might cause such an issue. Thank you, Sergey

(ITS#8783) LMDB on network share path is inconsistent after put data

Full_Name: Sergey Brester Version: all, also latest master 4d5e2d2a2ac38b9d56b6ba73187c325024718167 OS: windows URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (80.154.98.131) If I save many data into LMDB file placed in network share, only the latest key is really in the database after reopen. Tested single threaded (1 process, 1 thread). No matter which flags supplied to mdb_env_open... So repeateable writing of 10 keys (total 960 times) should result in: Target-state: 10 keys { "some-key-0": "951", "some-key-1": "952", "some-key-2": "953", "some-key-3": "954", "some-key-4": "955", "some-key-5": "956", "some-key-6": "957", "some-key-7": "958", "some-key-8": "959", "some-key-9": "960" } After reopen of database you'll see: Actual-state: 1 key { "some-key-9": "960" } Doing the same on local drive works fine and actual state is equal target state.
