Full_Name: Howard Chu Version: 2.4 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (199.188.194.66) Submitted by: hyc syncprov can deadlock itself if a persistent search is active while a group entry controlled by autogroup is being modified. Fix coming shortly.

Unfortunately, I do not know how to reproduce this bug, but it is a recurring one. Maybe the following information can help you, - My software opens the database in MDB_NOSYNC mode, and performs a mdb_env_sync(env, 1) every second or less. A mdb_env_sync can happen at the same time of any other operation (i.e. mdb_txn_commit). I didn't put any lock mechanism. Could this expln n such situation ? - mapsize is currently 512MiB. Previous versions of the software set to smaller values (the database had not been rebuilt since). I'd be happy to provide more information if you need. Thank you for your support and this amazing IP. Regards

I checked and the appropriate credentials are used, nothing in the configur= ation changed between this version (2.4.39-8) and the previous one(s). These are the corresponding lines of the slapd.conf on the consumer: overlay chain chain-rebind-as-user FALSE chain-uri "ldap://ldap_provider:389" chain-rebind-as-user TRUE chain-idassert-bind bindmethod=3D"simple" binddn=3D"cn=3DManager,ou=3Datlas,o=3Dcern,c=3Dc= h" credentials=3D"ldap_manager_pw" mode=3D"self" #chain-tls start chain-return-error TRUE Unless you spot something wrong in the configuration attached to the initia= l mail, there should be something else different between this non-working v= ersion and the previous ones, Thank you and best regards, Diana On 17 Feb 2015, at 12:55, hyc(a)symas.com wrote: > Diana.Scannicchio(a)cern.ch wrote: >> Is there anybody that could help on this issue?=3D20 >> this version of openldap is not usable, so I would like to understand wh= ich=3D >> is the problem and if can be fixed. >> Thank you and best regards, >=20 > The error message you're referring to was added in the patch for this ITS >=20 > http://www.openldap.org/its/index.cgi/Software%20Bugs?id=3D6851;selectid= =3D6851 >=20 > Check that you've configured appropriate credentials if you're using idas= sert on the target URI. >>=20 >> Diana >>=20 >>=20 >> On 02 Feb 2015, at 20:56, diana.scannicchio(a)cern.ch wrote: >>=20 >>> Should not, I did not enable it in the slapd.conf. >>> =3D20 >>> Diana >>> =3D20 >>> On 02 Feb 2015, at 20:34, <michael(a)stroeder.com> <michael(a)stroeder.com>= w=3D >> ro=3D3D >>> te: >>> =3D20 >>>> Is SSL/TLS part of the game? >>>> =3D3D20 >>>> Ciao, Michael. >>>> =3D3D20 >>>> =3D3D20 >>>> =3D3D20 >>>> =3D3D20 >>> =3D20 >>> - >>> Diana Scannicchio >>> University of California, Irvine >>> ATLAS TDAQ SysAdmin group >>> Office: +41 22 76 75240 >>> OnCall: 164851 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>> =3D20 >>=20 >> - >> Diana Scannicchio >> University of California, Irvine >> ATLAS TDAQ SysAdmin group >> Office: +41 22 76 75240 >> OnCall: 164851 >>=20 >>=20 >>=20 >>=20 >>=20 >>=20 >>=20 >>=20 >>=20 >>=20 >=20 >=20 > --=20 > -- Howard Chu > CTO, Symas Corp. http://www.symas.com > Director, Highland Sun http://highlandsun.com/hyc/ > Chief Architect, OpenLDAP http://www.openldap.org/project/ >=20 >=20 >=20 - Diana Scannicchio University of California, Irvine ATLAS TDAQ SysAdmin group Office: +41 22 76 75240 OnCall: 164851

Re: (ITS#8027) ldapsearch -E deref=member: crashes slapd

Of course not. But slapo-deref is not installed or enabled by default. And since it is undocumented, no one would enable it by accident - most don't even know that it exists.

Re: (ITS#7796) LDAP_DEBUG_TRACE for "not indexed" log messages

Could you please add this patch to RE24? The amount of unneeded log messages in my setup with lots of ACLs using non-indexed filters is huge and I hate to maintain local build patches. Ciao, Michael.

(ITS#8061

I compiled a new instance of OpenLDAP from the git Master and the bug seems to be fixed. After parsing the git commits, I found a link back to a bug report : http://www.openldap.org/its/index.cgi/Software%20Bugs?id=7975;selectid=7975 It's similar to mine (but didn't come up in my searches, sorry) so my bug report can be closed.

(ITS#8061) Base object returned when searching with scope: singleLevel (1) when using mdb backend and paged results
by frederic.jacquot＠insa-lyon.fr 18 Feb '15

18 Feb '15

Full_Name: Frederic Jacquot Version: 2.4.40 OS: Ubuntu 14.04.1 LTS URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (134.214.252.20) Hi, I think I discovered a bug with OpenLDAP 2.4.40, using an mdb backend. If you do a simple search request with no pagination and a SingleLevel (1) scope, everything is ok. But if you enable pagination for the same search, the base will also be returned in the search results. This breaks RFC 4511, paragraph 4.5.1.2 (SearchRequest.scope) : "singleLevel: The scope is constrained to the immediate subordinates of the entry named by baseObject." To reproduce the problem, I compiled a fresh OpenLDAP 2.4.40 with --enable-mdb. I then created a root entry : dn: dc=my-domain,dc=com objectClass: dcObject objectClass: organization dc: my-domain o : my-domain You can now compare search results. This is for a simple search : ldapsearch -s one -h localhost -b "dc=my-domain,dc=com" -w secret -D "cn=Manager,dc=my-domain,dc=com" # extended LDIF # # LDAPv3 # base <dc=my-domain,dc=com> with scope oneLevel # filter: (objectclass=*) # requesting: ALL # # search result search: 2 result: 0 Success Which is ok. This is the same query with paged results enabled : ldapsearch -s one -h 134.214.182.252 -b "dc=my-domain,dc=com" -w secret -D "cn=Manager,dc=my-domain,dc=com" -E pr=100 # extended LDIF # # LDAPv3 # base <dc=my-domain,dc=com> with scope oneLevel # filter: (objectclass=*) # requesting: ALL # with pagedResults control: size=100 # # my-domain.com dn: dc=my-domain,dc=com objectClass: dcObject objectClass: organization dc: my-domain o: my-domain # search result search: 2 result: 0 Success control: 1.2.840.113556.1.4.319 false MAUCAQAEAA== pagedresults: cookie= # numResponses: 2 # numEntries: 1 The base object is returned, but shouldn't be. This behaviour shows an endless recursive directory hierarchy in some LDAP browsers (sometimes crashing them). It can also create endless loops in some applications querying the LDAP server (Canon Uniflow in my case). Regards, Frederic Jacquot INSA Lyon
