(ITS#6892) Segfault in Syncprov overlay

Full_Name: Duncan Idaho Version: 2.4.25 OS: RHEL 5.5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (204.10.36.147) In my configuration slapd segfaults within a few hours repeatably when a NULL value is somehow passed as a filter to test_filter in the syncprov overlay. I'm running "threads 64" as I have 62 consumers connecting and this was required to prevent unrelated searches from timing out when all the consumers connect at once. Program received signal SIGSEGV, Segmentation fault.

(ITS#6891) pcache crashes after 2.4.25 upgrade; complains of unclean shutdowns and missing DB_CONFIGs after every restart
by tgates81＠gmail.com 05 Apr '11

Full_Name: Tyler Gates Version: 2.4.25 OS: Ubuntu 10.04 LTS URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (65.184.61.44) After upgrading from 2.4.24 to 2.4.25 my pcache overlay using hdb backend first failed to start with messages complaining about a missing suffix. Now that I've added one I'm getting the following message: hdb_db_open: database "dc=example,dc=com": unclean shutdown detected; attempting recovery. hdb_db_open: warning - no DB_CONFIG file found in directory /var/lib/ldap: (14).#012Expect poor performance for suffix "dc=example,dc=com". slapd starting bdb(dc=example,dc=com): PANIC: fatal region error detected; run recovery last message repeated 3 times But DB_CONFIG does exist and has proper permissions and the unclean shutdown message repeats after every restart. I've never had to add the suffix to the pcache backend database before and the documentation examples (http://www.openldap.org/doc/admin24/proxycache.html) never mention it either.

(ITS#6890) SHA2 Password Hashing not working
by sudharma.thikkavarapu＠siemens.com 04 Apr '11

04 Apr '11

Full_Name: SUDHARMA Version: $OpenLDAP: slapd 2.4.23 (Apr 4 2011 13:48:06) OS: AIX URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (161.134.39.30) Hello, we are planning to encrypt the password using SHA2 so i have followed the steps that are required to use slapd-modules/passwd/sha2 in openLDAP code. I have modified the slapd.conf file to load the correct libraries etc.. when i try to generate the hash value for a password i get the following error. testdev# slappasswd -h {SHA512} New password: Re-enter new password: Password generation failed for scheme {SHA512}: scheme not recognized I have to mention that i had problems compiling the sha2 source code with the cc compiler but when i use the xlc i had no issues and compiled the source successfully. Here are the commands xlc -I/home/openldap-2.4.23/include -g -c slapd-sha2.c xlc -I/home/openldap-2.4.23/include -g -c sha2.c xlc -G -I/home/openldap-2.4.23/include -g sha2.o slapd-sha2.o -o slapd-sha2.so hope i haven't done anything wrong. Please suggest me how to make this work. Thank you much for your help. Best Regards, Sudharma

(ITS#6889) client libraries not linked against libfetch when building with it
by delphij＠FreeBSD.org 04 Apr '11

04 Apr '11

Full_Name: Xin LI Version: 2.4.25 OS: FreeBSD URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (206.40.55.65) When OpenLDAP is configured with fetch(3) support on FreeBSD, client libraries are not linked against libfetch.so, but rather link it against management binaries. This would cause problem when the consumer does not explicitly request libfetch.so linkage. We currently have a very brute force fix in FreeBSD port to solve this: http://www.freebsd.org/cgi/cvsweb.cgi/ports/net/openldap24-server/files/pat…

Re: (ITS#6888) slapd 2.4.23 terminating with 'SIGABRT'

The reason we are running 5 clients (each with 10 threads) performing concurrent wildcard searches on "unindexed attributes", is purely and simply.... load testing. the test seems reasonable enough that (with our current configuration) slapd should be able to handle it with terminating with a 'SIGABRT'... am i wrong in assuming this?
