https://bugs.openldap.org/show_bug.cgi?id=9524 Issue ID: 9524 Summary: Removing last entry in database triggers MDB_PROBLEM Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- With a fresh database, if you have have an open read transaction, and you create a new entry in a write transaction and commit it, and then create a new transaction and delete that entry, when you commit, it will return an MDB_PROBLEM from approximately line 4408 from the mt_loose_count/dirty_list check. This seems to occur on mdb.master3, but not mdb.master. Here is a minimal example/test-case of how to reproduce: MDB_env* env; mdb_env_create(&env); int rc, flags = 0; mdb_env_open(env, "test", flags, 0664); MDB_txn* readonly_txn; mdb_txn_begin(env, nullptr, MDB_RDONLY, &readonly_txn); MDB_txn* txn; MDB_dbi dbi; mdb_txn_begin(env, nullptr, 0, &txn); mdb_dbi_open(txn, nullptr, MDB_CREATE, &dbi); MDB_val val; val.mv_data = (void*) "test"; val.mv_size = 4; mdb_put(txn, dbi, &val, &val, 0); mdb_txn_commit(txn); mdb_txn_begin(env, nullptr, 0, &txn); mdb_del(txn, dbi, &val, nullptr); rc = mdb_txn_commit(txn); // this returns MDB_PROBLEM (let me know if this should be submitted differently) -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9911] New: MDB_PROBLEM: Unexpected problem - txn should abort, because of mdb_page_loose

Reverting this commit solves the problem. This commit seems to be a non essential optimization. But you will see into it as i am not so familiar with the refactoring that Hallvard Furuseth did back in July 2017. It would be nice to have an official fix from you, instead of this revert I did temporally to be able to continue working. -- You are receiving this mail because: You are on the CC list for the issue.

Using self signed certificate causes ldap_sasl_bind_s() error
by rinchive＠gmail.com 20 Sep '22

20 Sep '22

Hi. I'm trying to use C code of your gitlab repository to make a program that can bind to remote LDAP server. I have some problems with using self signed certificate in openldap server. When I try to connect to remote LDAP server with SSL connection, ldap_sasl_bind_s return this error : "Can't contact LDAP server (-1) additional info: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed (self signed certificate in certificate chain) " At the same time, server prints like this : 632973de conn=1018 fd=12 ACCEPT from IP=172.17.0.1:57250 (IP=0.0.0.0:636) TLS: can't accept: A TLS fatal alert has been received.. 632973de conn=1018 fd=12 closed (TLS negotiation failure) I use docker image to build an openldap server for test and made my own CA certificates, server's private key and certificate for TLS connection. On client program side, I set some options related to TLS connection. I set LDAP_OPT_X_TLS_REQUIRE_CERT to LDAP_OPT_X_TLS_NEVER, and set LDAP_OPT_X_TLS_CACERTDIR, LDAP_OPT_X_TLS_CACERTFILE to the path that server's CA certificate file is stored. I think I set all options that I can do on client side, but client always verify server's certificate and return "certificate verify failed (self signed certificate in certificate chain)" this error. It is okay to bind without TLS negotiation on client program. Also I made a connection with the server using LDAPAdmin which is windows ldap client program and it makes TLS connection successfully. Is there other option or some codes to be executed to make a secure connection using self signed certificate? I've been struggling with this error for a couple of weeks and not able to find a solution. Can I make a TLS connection with the server that uses the self-signed certificate?

[Issue 8912] incorrect rootDSE (namingContexts)
by openldap-its＠openldap.org 15 Sep '22

15 Sep '22

https://bugs.openldap.org/show_bug.cgi?id=8912 --- Comment #8 from Cliff <cwheat(a)sterlingandzoe.info> --- Thank you for the reply and my apologies for the lack of clarity. Upon further testing, I was unable to reproduce the behavior using a command line application, ldapsearch. I should have done that before submitting the bug. If you have been assigned this issue then please close it. I hope this is more clear: When attempting to display all of the subordinate partitions in the root partition I was only able to see a portion. Those displayed results were all of the same naming context, relative DN c=* or o=*. There is some form of filtering done by the LDAPBrowser GUI. This does not happen using ldapsearch. The problem is not in slapd as I initially thought. Thanks again for your reply. --Cliff On Monday, September 12, 2022 at 12:44:54 PM EDT, <openldap-its(a)openldap.org> wrote: https://bugs.openldap.org/show_bug.cgi?id=8912 --- Comment #7 from Quanah Gibson-Mount <quanah(a)openldap.org> --- (In reply to Cliff from comment #6) > On Fedora Core 36, > @(#) $OpenLDAP: slapd 2.6.2 (Aug 15 2022 00:00:00) $ > openldap > Included static backends: > config > ldif > monitor > mdb > using LDAP Browser\Editor v2.8.1: > > While attempting to add subordinate naming contexts off of base DN "" > (RootDSE), slapd will only show such subordinate naming contexts if they are > of the same RDN attribute.

Hello, I honestly have no idea what you're trying to say here, but it seems thoroughly unrelated to this issue. If you feel that you've found an actual bug, then you should file something new with complete reproduction steps. If you're having issues understanding how to execute queries to OpenLDAP correctly please email the openldap-technical list.
