Search control forwarding
by Javier Sanz 30 Sep '10

30 Sep '10

Hi, Is there any way to make back_meta or back_ldap forward server controls used in the queries to the LDAP servers?. I have a configuration where a back_meta acts as a proxy to an Active Directory, and currently clients are unable to make searches which return more results than the page size configure int AD, which by default is 1000, because, altough both their clients and AD support paged searches, back_meta does not forward it AFAIK. Thanks, Javier

ACL Question
by Diego Lima 30 Sep '10

30 Sep '10

Hello all, I have the following structure on my LDAP server: ou=Misc,dc=diegolima,dc=org ou=Users,dc=diegolima,dc=org Under users I have some user accounts, such as cn=user1,ou=Users,dc=diegolima,dc=org. I'd like to allow users to create an OU under ou=Misc as long as the OU had the user's name, such as ou=user1,ou=Misc,dc=diegolima,dc=org for user1 or ou=user2,ou=Misc,dc=diegolima,dc=org for user2, however I wouldn't like to simply create an ACL such as: access to dn.exact="ou=Misc,dc=diegolima,dc=org" by * add as this ultimately allows user1 to create an ou named "ou=user2,ou=Misc". What I first tried was adding an ACL like this: access to dn.regex="^ou=([^,]+),ou=Misc,dc=diegolima,dc=org" by dn.exact,expand="cn=$1,dc=diegolima,dc=org" write by * none However I receive an error telling me that I need write access to the parent entry to create this, and if I use the first ACL I seem to be able to create OUs without any naming restriction. Is there even a way to accomplish this? Thank you very much! -- Diego Lima

AD authentication over open ldap
by Florian Harmuth 30 Sep '10

30 Sep '10

Hello all, at the moment i try to realize an authentication against an active directory over a ldap server. With my attached config this to works if i provide the a bind dn like this "username(a)mydom.lan". A few of our servers try to authenticate the users with a dn like this "uid=username,dc=mydom,dc=lan". Is it possible to convert this dn to the other format before sending it to the aactive directory server? Best regards and sorry for my terrible english flo <slapd.conf> include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/inetorgperson.schema # Where the pid file is put. The init.d script # will not stop the server if you change this. pidfile /var/run/slapd/slapd.pid # List of arguments that were passed to the server argsfile /var/run/slapd/slapd.args # Read slapd.conf(5) for possible values loglevel 65535 # Where the dynamically loaded modules are stored modulepath /usr/lib/ldap moduleload back_ldap moduleload rwm database ldap suffix "dc=mydom,dc=lan" rebind-as-user yes uri "ldap://10.1.2.210 ldap://10.2.2.210" protocol-version 3 overlay rwm rwm-map attribute uid samaccountname rwm-map attribute member memberOf rwm-map objectclass inetOrgPerson user </slapd.conf>

Samba 3.5.5 with ldap backend crash slapd 2.4.23 !!!
by Frank Bonnet 30 Sep '10

30 Sep '10

Hello We use here Openldap 2.4.23 server running on a FreeBSD 8.1 server compiled on the server from the FreeBSD ports. It runs well since weeks. We also use a Samba server 3.5.2 with ldap backend on a Linux Debian Lenny server compiled from source on the server, everything was running well ... Last Monday I decided to upgrade the Samba server to the latest "Stable" release ( 3.5.5 ) then the nightmare begins ... Few minutes after I restart ( reboot the server ) the samba server the slapd daemon violently crashed. After few restart it was still the same : slapd works well if samba is stopped , Linux clients can authenticate without problem, if I start samba daemons , windows clients begin to connect and after few seconds slapd crash ... Any infos welcome ! Thanks

rfc2307bis and samba woes
by Victor Mataré 29 Sep '10

29 Sep '10

Hi list, Has anybody else gone through this posixGroup vs. groupOfNames pain? I mean, what kind of a design accident is this? Samba 3.4 seems unable to deal with rfc2307bis (which makes posixGroup auxiliary). I'll definitely talk to the samba list on this, too, but maybe somebody can tell me what the status of the rfc2307bis mess is, anyway. Looks to me like this whole issue has been rotting at the ietf for like 10 years and nobody seems to care about it. Except openSuSE, who allegedly use it by default. No idea how they made samba work with it, though. In my naïve mind the patch should be almost trivial (just use groupOfNames as structuralObjectClass and add a dummy member), but I suspect it's not in vanilla samba because of the vague status of rfc2307bis. So... any insight on this whole rfc2307bis scenario is highly appreciated. Thanks a lot in advance.

Too many executing vs syncrepl
by Jorgen Lundman 29 Sep '10

29 Sep '10

Hello list, So we are in the middle of a major upgrade of our OpenLDAP software, so it is a bit unfortunate that I have to track down issues at the same time. os: Solaris 10u8 x86 old: openldap-2.3.41 db-4.2.52.NC-PLUS_5_PATCHES new: openldap-2.4.23 db-4.8.30.NC We noticed that syncrepl stopped on pop01, pop03 and pop06 yesterday and fell behind. The only hints in slaplog was: Sep 28 11:23:09 pop06.unix slapd[29027]: [ID 968320 local4.debug] do_syncrep2: L DAP_RES_INTERMEDIATE - NEW_COOKIE Sep 28 11:24:44 pop06.unix slapd[29027]: [ID 763815 local4.debug] connection_inp ut: conn=123099 deferring operation: too many executing Sep 28 11:24:44 pop06.unix slapd[29027]: [ID 763815 local4.debug] connection_inp ut: conn=123099 deferring operation: pending operations Sep 28 11:24:48 pop06.unix last message repeated 72 times and there were no more syncrepl messages until we restarted slapd, 2 hours later. I wonder if the syncrepl connection received "too many executing". Is that possible? Can we make it so sync connections get higher priority as it were. In this case, it is new-ldap syncrepl to old-ldap for loopback lookups (dovecot). Now, I would guess that getting "too many executing" is undesirable. Googling around it seems that what happens is that; one connection has more than half of the connection-pool operations already, and gets deferred. What does "one connection" mean? From one IP (all connections are over loopback, except for syncrepl), or is it operations from one-tcp-stream? Or it some other kind of cookie, like rid? Can I get slapd to tell me which connection it actually means? Having looked at the sources, it does not seem to have that ability, but I could always add our own prints. At least to get the IP of the requester. (I tried "conns" in LogLevel, but it prints all select() calls, and is unfortunately unrealistic to run on live servers. Currently I have 'stats' running.) Or rather than hacking at the sources, should I invest in getting the overlay "monitor" to run? Would it show why we receive "too many executing". I have also noticed a considerable performance drop when moving from old version to new version, and not entirely sure if that is something we can do something about.

Hi Quanah, you're right. Those weren't my configuration but only an indication of the order in which those "groups" of directives appear in my slapd.conf config file. This is my exact fragment of configuration which involves overlays: BEGIN ------------------------------------ overlay ppolicy ppolicy_default "cn=default,ou=Policies,dc=lan,dc=mycorp.it" ppolicy_use_lockout ppolicy_hash_cleartext ppolicy_forward_updates overlay syncprov syncprov-checkpoint 50 10 syncprov-sessionlog 150 overlay auditlog auditlog /srv/logs/ldap/ldap03_audit.log overlay accesslog logdb cn=log03,dc=mycorp.it logops all logold (objectclass=inetOrgPerson) logpurge 7+00:00 04:00 logsuccess FALSE overlay sssvlv sssvlv-max 4 sssvlv-maxkeys 5 overlay memberof memberof-group-oc groupOfNames memberof-member-ad member memberof-memberof-ad memberOf memberof-dn cn=Manager,dc=lan,dc=mycorp.it memberof-dangling ignore memberof-dangling-error 80 memberof-refint TRUE END ------------------------------------ I use dynamic modules.

You obviously still have a lot to learn about using mailing lists, though. 1) Don̈́'t top post. 2) Reply to the list, not to individuals. http://www.freebsd.org/doc/en/articles/mailing-list-faq/etiquette.html is a good place to start. -- Bjørn

Hi, Please reply to the list. On 09/28/2010 08:55 PM, Cole wrote: > Sorry about the config files. I've attached them. These files are > exactly them same on the server and the client, according to diff. If the config files are identical while you have OpenLDAP running on one system and not on the other, I would assume some differences between the files would be useful. Anyways, from your config files, you need to learn how to use ldapi:// in your libnss-ldap.conf file. Good luck :-) -- Bjørn
