Multi-master syncrepl config: excluding olcSaslHost from replication
by Kyle Brantley 22 Aug '15

22 Aug '15

I'm working on a full multi-master slapd setup, where both the cn=config database as well as the actual database are fully replicated. All access to the slapd instances is gated with GSSAPI (the only notable exception being the syncrepl users, which I'm working on converting over to GSSAPI anyway). However, I need to be able to configure olcSaslHost on a per-server basis. Server A will have a different value for olcSaslHost than server B will. While I want to replicate cn=config, I don't want to replicate the olcSaslHost attribute. I've tried two things, and neither have worked: 1) Configuring exattrs="olcSaslHost" in the olcSyncrepl statements for cn=config. * This allows me to configure the attribute, but as soon as there is any other change to cn=config, it wipes the attribute out across all of the nodes. 2) Updating the ACL for the syncrepl user to not have access to the olcSaslHost attribute. * Unfortunately, this has similar behavior to the above: making a change on one node will wipe the olcSaslHost attribute out of all of the nodes. How best can I go about doing this? I was hoping that olcSaslRealm was multi-value and could be configured in a manner similar to olcServerID, but that isn't the case. I was hoping that denying access to the attributes (via ACL or olcSynrepl config) would make the syncrepl engine ignore the attribute, but because it can't see it on the node where the attribute was changed, but it can see it on the downstream nodes, it wipes the attribute out entirely. Any help / suggestions welcome. Thanks, --Kyle

ClearText Passwords in slapcat: please provide some inputs
by Manuel Afonso 21 Aug '15

21 Aug '15

Hi people, I am using ubuntu and phpldapadmin to manage openldap. I have here a big issue: when using phpldapadmin/openldap, all the times there is (for each user/entry) a field with cleartextPassword: <cleartextpassword> (this is seen in slapcat output) What I want is to put in place a mechanism where there is no plain text field with the password in clear in each entry of openldap. I have read about ppolicy overlay, slappasswd and so on but so far I was not able to figure out how to avoid this annoying clear text password available when I do a slapcat (as root of course) Does anybody had such an issue ? Any ideas or links to point for a solution? Another question: is it possible that this clear text password is somehow needed for the correct operation of openldap? Thanks a lot for your time and (I hope) help. Kind regards, Manuel - Lisbon PT This is what I got for the user mafonso (me) when doing a slapcat > output : (as can be seen there is the field cleartextPassword: with pass in clear text) dn: cn=mafonso,ou=***,dc=***,dc=***,dc=***,dc=pt objectClass: ****Person objectClass: mailAccount objectClass: sambaSamAccount objectClass: posixAccount objectClass: top givenName: Manuel sn: Afonso displayName: Manuel Afonso cn: mafonso mailacceptinguser: 1 maildrop: mafonso(a)***.pt intranetRole: cn=**,ou=**,ou=**,dc=**,dc=**,dc=**,dc=pt ... portalRole: *** ... gidNumber: 516 sambaSID: *** uidNumber: 1399 uid: mafonso homeDirectory: /home/mafonso intranetStatus: U sambaAcctFlags: [UX] loginShell: /bin/false mailacceptinggeneralid: mafonso@**** mailacceptinggeneralid: ***(a)**.**.**.pt userPassword:: e1N.... cleartextPassword: <cleartextpassword> sambaNTPassword: D6... sambaLMPassword: 45...

Re: Slapd is coming down

Hello quanah! Yes, I know, my SO killed the slapd because it was configured. But I don't have any other service in the server, only the openldap. Quanah, below follow the information: - Openldap-syncrepl: 2 GB - Openldap-translucent: 567 MB Now, about the slapd process.

ACL rule: getting crazy with it.
by Simone Taliercio 20 Aug '15

20 Aug '15

Hi All, I've Jasig CAS connected to OpenLDAP for users authentication. My LDAP Schema is the following: dc=com dc=companyA,dc=com ou=user,dc=companyA,dc=com dc=companyB,dc=com ou=user,dc=companyB,dc=com I would like to give to a specific user (cn=admin,ou=user,dc=companyB,dc=com) the ability to create inetOrgPerson objetcs under ou=user,dc=companyA,dc=com and the restriction to have only search access to ou=user,dc=companyB,dc=com where actually some attributes should be hidden (such as userPassword). I tried several ACL but always with one strange problem: a user is able to login via CAS. Then, he/she logouts and if try with a different account then LDAP returns DN_RESOLUTION_FAILURE. That issue is occurring even with a simple ACL such as: access to * by self write by anonymous auth by users search The only way to workaround that issue is removing any ACL or leaving "by users read". As DN bind I'm using dc=com. Any suggestion? I cannot understand if focusing on CAS for this issue, or ACL LDAP side. Thanks a LOT for the support! Simone

0.9.16 build problems for android
by Kristoffer Sjögren 19 Aug '15

19 Aug '15

Hi This is a long shot. Just upgraded LMDB to 0.9.16 for lmdbjni (Java bindings for LMDB) and when building for android-ndk-r10e I get a build error complaing about undeclared PTHREAD_MUTEX_ROBUST [1]. The build procedure uses automake and is quite complex because of Java JNI bindings but maybe the build error/output rings a bell anyway? The build works fine with LMDB 0.9.15. Cheers, -Kristoffer [1] src/mdb.c:4636:49: error: 'PTHREAD_MUTEX_ROBUST' undeclared (first use in this function) [2] Full build output - http://pastebin.com/JwreP0dZ [3] agcc #!/bin/bash $NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc --sysroot=$NDK/platforms/android-19/arch-arm -DMDB_DSYNC=O_SYNC $@

Upgrading OpenLDAP from 2.4.39 to 2.4.41
by Brian Wright 18 Aug '15

18 Aug '15

We have a 2-way master production cluster actively running 2.4.39. We are wanting to upgrade to 2.4.41 (we haven't yet internally certified 42). What is the best practices around upgrading this cluster while keeping at least one of the servers online? Is it replication-safe to have one node on 2.4.39 and one on 2.4.41 for a short period? If not, I can temporarily comment out the syncrepl statements until both servers are on 2.4.41 and then reenable replication after both are upgraded. We can live with short inconsistency period between the servers during the upgrade of the servers until we can resume replication. Also, is the DB format fully compatible between these two versions or would it be better to reload the DB new from an LDIF backup on 2.4.41? Is there an upgrade doc somewhere that discusses these issues? Thanks. -- Signature *Brian Wright* *Sr. UNIX Systems Engineer * 901 Mariners Island Blvd Suite 200 San Mateo, CA 94404 USA *Email *brianw(a)marketo.com <mailto:brianw@marketo.com> *Phone *+1.650.539.3530** *****www.marketo.com <http://www.marketo.com/>* Marketo Logo

OpenLDAP proxy referral via SSL
by Declan O'Doherty 17 Aug '15

17 Aug '15

I am trying to set up an OpenLDAP server (2.40) on CentOS 6 that uses a proxy referral to another LDAP server (OpenDJ) , all via SSL/TLS The referral works if I do not use SSL but when I configure slapd.conf to require certs, I get an invalid password error: res_errno: 49, res_error: <Invalid password.>, res_matched: <> The proxy is configured to use SASL EXTERNAL binding but when connecting to the OpenDJ service, it binds anonymously: ldap_back_dobind_int: DN="<certificate DN>" without creds, binding anonymouslyldap_sasl_bind The same configuration works on Windows using OpenLDAP 2.38 Here is the configuration for the ldap backend in slapd.conf: database ldap suffix "ou=organization unit, o=organization" uri "ldaps://test.ldap.com:636/" chase-referrals yes idassert-bind bindmethod=sasl saslmech=EXTERNAL binddn="O=ORG,OU=ORGUNIT,C=US" tls_cacert="/path/to/ca cert.pem" tls_cert="/path/to/server cert.pem" tls_key="/path/to/server key.pem" tls_reqcert=demand mode=self Thank you
