(ITS#7118) [PATCH] Improve SASL plugin handling
by thomas＠koeller.dyndns.org 26 Dec '11

26 Dec '11

Full_Name: Thomas Koeller Version: 2.4.28 OS: Linux x86_64 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (80.171.14.55) I had a problem with slapd always segfaulting. A little debugging revealed that slapd allocated the thread-safe version of 'struct ldapoptions', since it is linked with libldap_r.so. However, the destructor function ldap_int_destroy_global_options() invoked during cleanup seemed to be the non-threadsafe version which assumes a different layout of 'struct ldapoptions' (the ldo_mutex field is missing). I noticed that that SASL loaded all its plugins, including the 'ldapdb' module which is present in my SASL installation, and that ldapdb.so was linked against the non-threadsafe libldap.so. I still do not quite understand the exact reason why this confusion arose, because AFAIK theoretically both libraries should be able to co-exist. However, I did not investigate that problem any further, because I think that loading all sasl plugins is just wrong, because slapd only uses its own internal auxprop module and does not need any of them. I tried the proposed method of excluding ldapdb by having a slapd.conf file containing 'pwcheck_method: auxprop' and 'auxprop_plugin: slapd',but that did not improve anything. I therefore changed slapd to no longer load any sasl plugins whatsoever. With this change, everything works fine. Btw., my SASL installation is cyrus-sasl-2.1.25. Here is the patch I created, along with the required legalese: The inlined patch below is derived from OpenLDAP Software. All of the modifications to OpenLDAP Software represented in the following patch(es) were developed by Thomas Koeller <thomas(a)koeller.dyndns.org>.

(ITS#7114) Password synchronization is not working
by venkata.udumula＠yahoo.co.in 20 Dec '11

20 Dec '11

Full_Name: venkata reddy Version: 2.4.26 OS: Windows server 2008 R2 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (170.252.70.4) Hi, I am setting up a Forefront Identity Manager (FIM) infrastructure. I installed the FIM software. Our Active Directory is already exists. And I have to use another LDAP system for testing the my FIM setup. I chose OpenLDAP for Windows, as i am comfortable with only windows applications. I am assuming that your Tech support team would have some idea of what FIM does. I have setup the management agents on the FIM synchronize server to FIM, AD and OpenLDAP. For FIM and AD management agents are available by default in the FIM synchronization server. But for OpenLDAP i used OpenLDAP XMA management agent provided by sourceforge. With the management agents I am able to move the user and group objects between all the systems successfully. When a new user is created the password is moved to the OpenLDAP system successfully. But when I change the password in the FIM portal, it should automatically update it in all the systems. It is updating in the FIM and AD. But not in OpenLDAP. I am not aware of any configuration settings I have to change to make it work in OpenLDAP. Could you please help me resolving this issue? At the time of installation instead of using the default port numbers I used 50000 for LDAP and 50001 for LDAPS. Is it a problem? Thanks,

(ITS#7113) broken read-only replica results in assertion failure and crash on master slapd process
by kacarstensen＠csupomona.edu 19 Dec '11

19 Dec '11

Full_Name: Kevan Carstensen Version: 2.4.28 OS: gentoo linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (134.71.248.23) During a heavy update load, replication from our master to one of our read-only ldap replicas started failing due to locking errors on the replica. Dec 14 04:01:08 pip-dev slapd[12645]: bdb(dc=csupomona,dc=edu): Lock table is out of available lock entries Dec 14 04:01:08 pip-dev slapd[12645]: => bdb_idl_delete_key: c_get failed: Cannot allocate memory (12) Dec 14 04:01:08 pip-dev slapd[12645]: conn=-1 op=0: attribute "memberUid" index delete failure Dec 14 04:01:08 pip-dev slapd[12645]: null_callback : error code 0x50 Dec 14 04:01:08 pip-dev slapd[12645]: syncrepl_entry: rid=001 be_modify failed (80) Dec 14 04:01:08 pip-dev slapd[12645]: do_syncrepl: rid=001 rc 80 retrying (these are due to an incorrect DB_CONFIG on the replica and are not related to this issue; I include them in case their impact on how/when the replica connects to the master are important) After about ten minutes of the replica trying and failing to start its syncrepl again, the master slapd crashed. Nothing in the master slapd logs specifically references the crash or indicates why it happened. Shortly after the replica broke, some unusual messages started showing up in the logs on the master: Dec 14 03:50:11 fosse slapd[22596]: connection_read(65): no connection! Dec 14 03:50:22 fosse slapd[22596]: send_search_entry: conn 7535053 ber write failed. Dec 14 03:50:32 fosse slapd[22596]: send_search_entry: conn 7535061 ber write failed. Dec 14 03:50:42 fosse slapd[22596]: send_search_entry: conn 7535065 ber write failed. Dec 14 03:50:56 fosse slapd[22596]: send_search_entry: conn 7535068 ber write failed. Dec 14 03:51:06 fosse slapd[22596]: connection_read(65): no connection! Dec 14 03:51:06 fosse slapd[22596]: connection_read(65): no connection! These continued until the crash, persisted after the master slapd was successfully restarted, and went away when I turned the broken replica off. I found similar behavior in a development setup similar to our production setup. There is one master, and there are two read-only replicas configured to replicate from the master with the following syncrepl stanza: syncrepl rid=1 provider=ldaps://master-2.ldap.csupomona.edu/ type=refreshAndPersist retry="10 10 60 +" searchbase="dc=csupomona,dc=edu" bindmethod=simple binddn=cn=slapd-syncrepl,ou=user,ou=service,dc=csupomona,dc=edu credentials=__PASSWORD__ (there are two replicas because I couldn't reliably produce a crash with one replica) The replicas have a DB_CONFIG that causes their replication attempts to fail with the same error as we saw in our production setup. The master database is initialized so that the replicas have a lot of changes to catch up on, as was the case when our production setup failed. Even with loglevel -1, there's nothing specifically referencing the crash in the master slapd's logs. There's an assertion failure in the backtrace: slapd: daemon.c:942: slapd_clr_write: Assertion `((slap_daemon[id].sd_index[(s)]) != -1)' failed. Program received signal SIGABRT, Aborted.

Full_Name: Nikolay Bogdanov Version: 2.4.23 OS: Debian/Ubuntu URL: ftp://ftp.openldap.org/incoming/sysinfo.txt Submission from: (NULL) (95.221.182.198) Dear ñolleagues, We used open ldap for three years. But some weeks ago we disided to restructurate our LDAP server. We did it, but there are a lot of users in the company. So we enabled the "rwm" overlay and added "oldDn" field in a schema. Futhermore, we use "memberof" overlay. As a result users can bind with their old dn. But after that slapd stops with deadlock everyday. What can you advice for us? And what information should we provide to solve this problem? (strace, gdb log, db_stat or something else?) With best regards, Nikolay Bogdanov. CJSC Flant.

I have reproduced the problem on 2.4.27. The mentioned ldapsearch query seems to have a high probability of success if run immediately after server start, which also seems true on 2.4.28. I threw in an extra Debug() line and op->op_protocol == 2 at the check. I'm rebuilding with as many debugging symbols enabled as possible to try to figure out what's going on.
