(ITS#8879) remove stale link in admin guide
by michael＠stroeder.com 17 Jul '18

17 Jul '18

Full_Name: Version: OS: URL: Submission from: (NULL) (213.240.182.26) There is a stale link in this section of the admin guide: https://www.openldap.org/doc/admin24/overlays.html#Password%20Policy%20Conf… Points to https://symas.com/blog/?page_id=66 which says "No Results Found" In general the admin guide should IMO not point to volatile external resources.

(ITS#8878) PBKDF2 Is Broken (1 in 64 hashes)
by jroose＠gmail.com 16 Jul '18

16 Jul '18

Full_Name: Jon Roose Version: HEAD OS: Linux URL: Submission from: (NULL) (68.134.180.197) The b64_to_ab64 function within the pbkdf2 password module is incorrect. When str[0] == '+' this function fails to convert that first character to a '.' The file in question is here: contrib/slapd-modules/passwd/pbkdf2/pw-pbkdf2.c and occurs at line 62 in the current version of the file. This occurs because when you write while (*p++), it changes the pointer and skips over the first character of str. This needs to be replaced with a for loop such as: for(char* p = str; *p; p++) This is a significant bug in this module, because it causes the hash algorithm to fail to be replicable by outside hash implementations 1 out of every 64 hashes on average.

The command output clearly shows that you are attempting to modify an entity that does not exist. If you need assistance with configuring OpenLDAP, please contact the openldap-technical(a)openldap.org mailing list, or one of the support services listed at <https://www.openldap.org/support/>. This ITS will be closed.

(ITS#8875) [Patch] Performance problems in back-mdb with large DITs and many aliases
by hbohnenkamp＠united-internet.de 06 Jul '18

06 Jul '18

Full_Name: Henrik Bohnenkamp Version: >= 2.4.44, HEAD OS: Ubuntu 18.04, Coreos 7.5 URL: https://github.com/hbo/openldap-mdb-deref-problem Submission from: (NULL) (77.176.95.241) This is a followup to http://www.openldap.org/lists/openldap-technical/201805/msg00065.html When MDB is used as backend database and with large DITs (O(10^6)) with many alias entries (O(10^5)), search requests with deref=always and scope=sub will take prohibitively long. Servers with a high request rate might become utterly unresponsive. This problem is not present in the HDB backend. In this issue I want to contribute two things: - a means to demonstrate the problem; this in the form of two scripts (bash/python) which set up a large test DIT and start two slapds (one HDB, one MDB) to allow easy comparisons of the performance - a patch to fix the problem The patch is certainly not production ready (or, if it is, it needs still exhaustive testing to inspire confidence), however, I think it is far enough to at least discuss the approach. Both the scripts and the patch, together with instructions how to use the former can be found here: https://github.com/hbo/openldap-mdb-deref-problem I am looking forward to discuss the patch.

There may still be releases of FreeBSD that linked libfetch against com_err, for whatever reason. You'd need to check that libfetch exists, and then check that linking against libfetch by itself succeeds or fails. (And if it fails, put com_err back in and try again.) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
