So how does the ldif generated by slaptest differ from what you are loading? If you slapcat your config that doesn't work, and compare it to the slapcat of what was generated from slaptest, what are the differences? Can you provide a gdb backtrace of the segmentation fault? --Quanah -- Quanah Gibson-Mount Sr. Member of Technical Staff Zimbra, Inc A Division of VMware, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

(ITS#7573) back-perl not working with cn=config
by benintechnologies＠yahoo.fr 11 Apr '13

11 Apr '13

Full_Name: Ben Version: 2.4.34 OS: Debian 6.0.4 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (41.79.217.116) Hi, I'm unable to set up a back-perl backend directly in cn=config mode. However, if I set it up in slapd.conf mode, and then convert it to cn=config mode, it works fine. It's not convenient, because I have to set all my perl backends up before converting to cn=config. Here's the ldif file I'm using to set up a back-perl backend in cn=config mode (it's inspired from the files I get by converting slapd.conf into cn=config with slaptest) # Load dynamic backend modules dn: cn=module,cn=config objectClass: olcModuleList cn: module olcModulepath: /usr/local/libexec/openldap olcModuleload: back_perl.la # Database settings dn: olcDatabase=perl,cn=config objectClass: olcDatabaseConfig objectClass: olcDbPerlConfig olcDatabase: perl olcSuffix: dc=mydomain,dc=org olcAddContentAcl: FALSE olcLastMod: TRUE olcMaxDerefDepth: 15 olcReadOnly: FALSE olcRootDN: cn=Manager,dc=mydomain,dc=org olcRootPW:: c2VjcmV0 olcSyncUseSubentry: FALSE olcMonitoring: FALSE olcPerlModulePath: /usr/local/etc/openldap/perl olcPerlModule: SampleLDAP olcPerlFilterSearchResults: FALSE And here's what I get when I try to load the file: ldapadd -Y EXTERNAL -H ldapi:/// -f perl-backend.ldif SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 adding new entry "cn=module,cn=config" adding new entry "olcDatabase=perl,cn=config" ldap_result: Can't contact LDAP server (-1) After that, if I start OpenLDAP I get a segmentation fault: root@ldap:/tmp# /usr/local/libexec/slapd -u openldap -g openldap -h "ldap:/// ldapi:///" -d 16383 . 51585496 perl backend db init Segmentation fault Like I said, if I set back-perl up in slapd.conf mode and then convert it to cn=config, everything works fine.

(ITS#7570) fix MDB_GET_MULTIPLE and MDB_NEXT_MULTIPLE behaviour
by claude.brisson＠gmail.com 11 Apr '13

11 Apr '13

Full_Name: Claude Brisson Version: HEAD OS: linux 64 URL: ftp://ftp.openldap.org/incoming/0001-fix-MDB_GET_MULTIPLE-and-MDB_NEXT_MULT… Submission from: (NULL) (84.103.74.130) In a db with MDB_DUPSORT flag, when there is only one DUP data for a key, F_DUPDATA is not set for this key, and there is no sub-cursor. In this case, the current behaviour of MDB_GET_MULTIPLE and MDB_NEXT_MULTIPLE is broken because they make the assumption that there is always a sub-cursor for DUP data, which is only true for keys with more than one DUP data. This patch address this specific issue. Notice: I, Claude Brisson, hereby place the following modifications to OpenLDAP Software (and only these modifications) into the public domain.

With -Q you get no useful information when an error occurs. Judging from the fact that no one has noticed this omission in the 6 years since -Q was added, I don't believe this particular feature has been of any importance one way or the other. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#7569) Patch: fixed a group enumeration bug in nssov
by tedcheng＠symas.com 10 Apr '13

10 Apr '13

Full_Name: Ted C. Cheng Version: HEAD OS: Solaris 8, 10, Linux URL: https://dl.dropbox.com/u/94235048/symas2255.patch Submission from: (NULL) (76.174.250.179) Importing a patch from Symas #2255 that fixed a group enumeration bug in nssov. The "rc" variable was not initialized in nssov write_group function. Theoretically, this bug should affect all platforms. Solaris 8 (64-bit) caught the bug because rc got a non-zero value when not initialized.
