We build with, % CPPFLAGS="-I/usr/local/krb5/include -I/usr/local/include/sasl" \ CFLAGS="-g" ./configure ... % make The 'CFLAGS' environmental will make sure the '-g' is injected into all generated makefiles. You can add -D_GNU_SOURCE there as well. We experienced the problems you described with <2.4.17. 2.4.17 fixed many of the segfault causes. We didn't repeat our stress test with multimaster and 2.4.17+ though, since we determined that deltasync was good enough for our purposes. It may very well be that 2.4.17+ would crash in multimaster mode with our stress test. The traceback you provided looks very similar to what we were seeing. If I have time I could run a test with 2.4.18 and multimaster and see what the results are... --- Tracy Stenvik University Computing Services 354843.

We are trying out the 2.4.18 release with a syncrepl Multi-Master setup and are experiencing similar problems as mentioned above. It will shut down with a segfault after heavy processing/updating of about 3000-17000 entries. We can reproduce this in about 10-20 minutes of heavy load. However, in this short execution time we can't find any signs of memory leakage. Unfortunatly I can't get any good tracebacks from gdb. I've tried compiling openldap with: export CPPFLAGS="-D_GNU_SOURCE -g". And also --enable-debug with /configure. Any pointers? This is the traceback I get, but I guess it isn't very helpful without the complete debugging information: (gdb) where #0 0x00007fc7e24fb8eb in syncprov_op_mod (op=0x7fc7aedb37d0, rs=<value optimized out>) at syncprov.c:1970 #1 0x000000000049531a in overlay_op_walk () #2 0x0000000000495e7a in ??

(ITS#6297) Allow hex in serverID directive

Full_Name: Rein Tollevik Version: CVS HEAD OS: Irrelevant URL: Submission from: (NULL) (2a01:600:0:1:21c:23ff:feab:61cd) Submitted by: rein The serverID directive is specified as a decimal integer value, but its hexadecimal value is used everywhere else. I.e in the syncrepl cookies and the ID field of the CSN attributes. This can be a bit confusing, so it would be nice if the hex value could be used in the configuration as well. A patch that allows this with an 0x prefix is coming. -- Rein Tollevik Basefarm AS

(ITS#6296) Strong bind doesn't work in slapd-ldap when used by slapd-relay or slapo-translucent
by mrubas＠kerio.com 17 Sep '09

17 Sep '09

Full_Name: Martin Rubas Version: 2.4.18, 2.4.15 OS: Windows, Linux/Ubuntu URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.113.184.10) Hello. I have to use slapd-ldap in "strong bind" mode which means that user binds using its own credentials and no identity assertion is performed. If slapd-ldap is the only module that is processing request then everything works fine. If slapd-ldap is processing an request forwarded from slapd-relay (with slapo-rwm) or request to database with slapo-translucent then the authentication problem occurs. First detected in OpenLDAP 2.4.15 but still present in 2.4.18. === Test Setup === Let's suppose that we have remote LDAP server with disabled anonymous binding. It could be Active Directory or OpenLDAP with following configuration: # --- config for remote server (remote.host.net) --- # [cut-off] command schema, slapd files & logs definitions # Load of modules: modulepath /usr/lib/ldap moduleload back_hdb.la # VERY IMPORTANT: Disable anonymous binding disallow bind_anon # Configuration Database database config rootdn "cn=admin,cn=config" rootpw secret # realone.net - local Repository database hdb suffix "dc=realone,dc=net" rootdn "cn=admin,dc=realone,dc=net" rootpw secret directory /var/lib/slapd/realone.net index objectClass eq index cn eq index uid eq Let's say there is a common content in database: # --- Directory content (just an overview) --- dn: dc=realone,dc=net # top, domain dn: ou=people,dc=realone,dc=net # organizationalUnit dn: ou=groups,dc=realone,dc=net # organizationalUnit dn: cn=idassert,dc=realone,dc=net # simpleSecurityObject,organizationalRole dn: cn=admin,dc=realone,dc=net # same as above dn: uid=super.account,ou=people,dc=realone,dc=net # inetOrgPerson,posixAccount, shadowAccount dn: uid=power.account,ou=people,dc=realone,dc=net # same as above dn: uid=basic.account,ou=people,dc=realone,dc=net # same as above dn: cn=admins,ou=groups,dc=realone,dc=net # posixGroup dn: cn=users,ou=groups,dc=realone,dc=net # same as above I want to use another OpenLDAP server that is configured with slapo-translucent: # --- config for local server (trans.local.net) --- # [cut-off] command schema, slapd files & logs definitions # Configuration Database database config rootdn "cn=admin,cn=config" rootpw secret # realone.net - local database extending the remote one database bdb suffix "dc=realone,dc=net" directory ./database/realone.net index objectClass eq index cn eq index uid eq overlay translucent uri ldap://remote.host.net:389/ chase-referrals true rebind-as-user true ... or with slapd-relay (this is probably very very very rare use case but I used it for debugging): # --- config for local server (relay.local.net) --- # [cut-off] command schema, slapd files & logs definitions # Configuration Database database config rootdn "cn=admin,cn=config" rootpw secret # domain (forwarded to remote repository) database ldap suffix "dc=realone,dc=net" uri ldap://remote.host.net chase-referrals yes # domain alias database relay suffix "dc=virtual,dc=net" relay "dc=realone,dc=net" overlay rwm rwm-suffixmassage "dc=virtual,dc=net" "dc=realone,dc=net" === Test Cases === Now, we can do usual search: ldapsearch -x -w secret -h <host-D <bindDN-b <baseDN-s sub "(objectClass=inetOrgPerson)" dn displayName mail (in my environment I should receive 3 records below ou=people,dc=realone,dc=net). But the story is getting interesting here. The command works only in cases that slapd-ldap is used directly: =================================================================================================== # | Host | BindDN | BaseDN | Result --+-----------------+----------------------------+-------------------+----------------------------- 1 | remote.host.net | cn=admin,dc=realone,dc=net | dc=realone,dc=net | Success (3 records) --+-----------------+----------------------------+-------------------+----------------------------- 2 | trans.local.net | cn=admin,dc=realone,dc=net | dc=realone,dc=net | Failure: Anon.bind.n.allwd. --+-----------------+----------------------------+-------------------+----------------------------- 3 | relay.local.net | cn=admin,dc=realone,dc=net | dc=realone,dc=net | Success (3 records) --+-----------------+----------------------------+-------------------+----------------------------- 4 | relay.local.net | cn=admin,dc=realone,dc=net | dc=virtual,dc=net | Success (3 records) !!!! --+-----------------+----------------------------+-------------------+----------------------------- 5 | relay.local.net | cn=admin,dc=virtual,dc=net | dc=virtual,dc=net | Failure: Anon.bind.n.allwd. =================================================================================================== The failures of case #2 and #5 are not expected because the connection to remote server is handled by slapd-ldap configured the same way like in case 3. The success in case #3 is correct (although I didn't expected it) and it was guide to solution. I noticed that each time the request fail the LDAP connection is correctly opened and bind request is successful. But the search request was processed using a new connection that was created for it and anonymous bind executed with failure. === Debugging === While debugging, I found that ldap_back_getconn() is called by ldap_back_bind() as well as ldap_back_search() request handlers. For operations other then op_bind it tests whether connection associated with Operation (op->o_hdr->oh_conn) was used for authentication in previous step. If slapd-ldap is NOT using identity assertion then it checks Operation using SLAP_IS_AUTHZ_BACKEND macro whether op->o_conn->c_authz_backend is not NULL and is equal to current backend. This test works fine is the slapd-ldap backend is the only which processes the LDAP request because op->o_conn->c_authz_backend is set in the binding handler of the frontend module - fe_op_bind(). In this, case the test succeeds and connection created during the binding is used also for searching. If the slapd-ldap module is used as nested module in slapo-translucent (case #2), then the fe_op_bind() sets variable op->o_conn->c_authz_backend to the backend extended by slapo-translucent. Macro SLAP_IS_AUTHZ_BACKEND returns false and a new LDAP connection is allocated causing failure due anonymouse binding. If the slapd-ldap module is target for slapd-relay then it behaves similar way. In case #5 the bind request is forwarded to slapd-ldap but slapd-relay is associated with connection as the backend who did the bind (op->o_conn->c_authz_backend) and subsequent search request fails the same way like above. The success in case #4 is a kind of singularity ;-) - bind request is forwarded directly from frontend to slapd-ldap and therefore op->o_conn->c_authz_backend is set correctly, the subsequent search request goes first to slapd-relay which forwards it to slapd-ldap but SLAP_IS_AUTHZ_BACKEND test succeeds. === Patches uploaded to ftp.openldap.org === mrubas(a)kerio.com-090917.slapd_back-relay_op.c.2_4_15.patch mrubas(a)kerio.com-090917.slapd_back-relay_op.c.2_4_18.patch mrubas(a)kerio.com-090917.slapd_overlays_translucent.c.2_4_18.patch Note: There is probably a better way how to fix that. I guess, that fix to slapd-ldap binding handler would be more efficient but I didn't find the right place to add code assigning the auth. backend to connection.

I haven't been able to monitor it constantly over its lifespan, as it takes anywhere from 24 to 36 hours of our load before failure, but what I have observed is that slapd continually grows (slowly) over the course of the test until it can't malloc any more. Core sizes run around 640Mb. The largest '__db' element is 1.9Gb. So, slapd behaves as if there's a slow memory leak, somewhere. Unless the delta syncrepl mechanism (on producer) has an insatiable memory appetite. Our test suite is heavy on updates, including mods to large-memeber groups (with 120K+ members). The consumer slapd never dies, and more or less keeps up with the change load from the producer. > > (If so, is it warranted given your load or is there a leak, etc etc...and of > course make sure you're up to date on the surrounding packages, OpenLDAP > isn't the only thing that can leak.) > openldap-2.4.17 db-4.7.25 (patch level 4) openssl 0.9.8e Red Hat Enterprise Linux Server release 5.4 Tracy

Actually no. slapd/main.c does lutil_CommenceStartupProcessing( serverName, slap_sig_shutdown ); which causes liblutil/ntservice.c:lutil_ServiceCtrlHandler() to call slap_sig_shutdown(-1). (The handler is stored in stopfunc.)

I have to extend this. The reported issue, slapd core dumping, only occurs if a sasl bind is initiated, slapd will not teminate on a simple bind. -Dieter --=20 Dieter Kl=C3=BCnter | Systemberatung http://dkluenter.de GPG Key ID:8EF7B6C6 53=C2=B037'09,95"N 10=C2=B008'02,42"E

(ITS#6287) ACL state cache problems
by rein＠OpenLDAP.org 08 Sep '09

08 Sep '09

Full_Name: Rein Tollevik Version: CVS HEAD OS: Irrelevant URL: Submission from: (NULL) (2a01:600:0:1:21c:23ff:feab:61cd) Submitted by: rein The ACL state cache appears to be broken, there are at least three problems with the current implementation: 1) The as_vi_acl is always NULL, which causes value-independent caching to newer function. Which is where the cache would be most useful.. 2) The current access mask is lost when the acl where processing can continue for a value dependent attribute is stored. I.e, if incrementally assigned access masks is in use it restarts with the wrong mask. 3) Access is always denied if a combined add/replace or delete/replace operation is performed on an attribute with a value-dependent acl. Yes, it is a completely stupid thing to do as the added or deleted value will be immediately replaced. Problem noted when debugging a stupid application.. A patch that fixes these problems is coming. -- Rein Tollevik Basefarm AS

Please keep replies to the ITS. OK, I understand. In this case, slapadd(8) needs to be able to load a LDIF without operational attrs and create them accordingly. Still, there's room for warning in that case if slapadd(8) is done for a database configured to use syncrepl. p.
