Ver2.4.23 - Delta syncrepl stops responding
by david m 19 Dec '11

19 Dec '11

I have a problem that has just started happening in the last few weeks. Replication of modifications and/or adds from one LDAP node to the other will work fine ( repl time <1s) for a while, then suddenly stop working all together. The only way to get replication working again is to restart each node 2 or 3 times (sometimes it comes back after 2 restarts, sometimes it takes 3). On the last restart, I usually find that one node is stuck in an infinite loop trying to process a transaction from the other node's accesslog - the only way to get around this is to delete the the accesslog entry (see below for accesslog entry and slapd output). Any ideas?

When I try to activate vacation on the webmail-system roundcube (the webmailer and the plugins are working fine) it says the the activation is stored, but when I have a look into the logs of round cube, they say: [16-Dec-2011 11:20:29] Could not add new values to attribute vacationActive: Object class violation: LDAP_OBJECT_CLASS_VIOLATION (65): [16-Dec-2011 11:20:29] Could not modify entry: Could not add new values to attribute vacationActive: Object class violation: LDAP_OBJECT_CLASS_VIOLATION: (1000): The slapd-logs shows the following when I try to activate vacation: conn=1221 op=4 MOD dn="cn=admin,dc=domain,dc=de" slapd[14608]: conn=1221 op=4 MOD attr=vacationActive serv slapd[14608]: slap_queue_csn: queing 0xb58969b6 20111216110200.012914Z#000000#000#000000 serv slapd[14608]: Entry (cn=ldapadmin,dc=folkwang-hochschule,dc=de), attribute 'vacationActive' not allowed serv slapd[14608]: entry failed schema check: attribute 'vacationActive' not allowed serv slapd[14608]: conn=1221 op=4 RESULT tag=103 err=65 text=attribute 'vacationActive' not allowed The following is my vacation.schema which I add to /etc/ldap/slapd.conf: attributetype ( 1.3.6.1.4.1.39116.1.1.11 NAME 'vacationActive' SINGLE-VALUE EQUALITY booleanMatch DESC 'A flag, for marking the user as being away' SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 ) attributetype ( 1.3.6.1.4.1.39116.1.1.12 NAME 'vacationInfo' SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 DESC 'Absentee note to leave behind, while on vacation' EQUALITY octetStringMatch ) attributetype ( 1.3.6.1.4.1.39116.1.1.13 NAME 'vacationStart' SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 DESC 'Beginning of vacation' EQUALITY octetStringMatch ) attributetype ( 1.3.6.1.4.1.39116.1.1.14 NAME 'vacationEnd' SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 DESC 'End of vacation' EQUALITY octetStringMatch ) attributetype (1.3.6.1.4.1.39116.1.1.15 NAME 'vacationForward' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} DESC 'Where to forward mails to, while on vacation' ) # # Objects start here # objectclass ( 1.3.6.1.4.1.39116.1.2.10 NAME 'vacation' SUP top AUXILIARY DESC 'Users vacation status information' MUST vacationActive MAY ( vacationInfo $ vacationStart $ vacationEnd $ vacationForward ) ) I imported a user with the object class vacation and the attributes vacationActive, vacationInfo . into my ldap database. There the import looks fine. The user has got the privileges to modify the vacation attributes. But when I try to modify the entries via vacation-plugin on roundcube, the above errors occur. Can anybody give me some advices, please? Thanks Andreas

OpenLDAP for Central Auth?
by Craig T 19 Dec '11

19 Dec '11

Hi, Has anyone successfully deployed OpenLDAP for central auth in a very mixed unix environment? With Host based access control? Plus any documentation would be really great. My needs; - Central Auth - Host based access control (e.g. user "John" from group "accounts" can't log into "development servers". - Caching for Client logins on laptops. I figure SSSD will be useful here? - Encryption (This looks pretty straight forward in the OpenLDAP 2.4 doco) Client OS's involved; - Solaris 9/10 - Fedora 15/16 - Centos 5/6 cya Craig

Adding an object class with required attributes to an existing entry
by Nick Milas 16 Dec '11

16 Dec '11

Hi, I want to add a new objectclass using an ldif; this objectclass requires some attributes (according to schema). I can't make it work. For posixAccount class, required attributes are: cn gidNumber homeDirectory uid uidNumber I already have cn and uid. I am trying: dn: uid=userx,ou=people,dc=example,dc=com changetype: modify add: ObjectClass objectClass: posixAccount uidNumber: 1700 homeDirectory: /var/members/userx gidNumber: 48 loginShell: /bin/false and it fails. I've tried other ways too, like including existing objectclasses in the LDIF (I've read about that in a blog), using a separate add statement for optional attribute loginShell, etc. but nothing worked. If the ObjectClass to add does not specify REQUIRED attributes in the schema, there is no problem in adding it. How should I formulate the LDIF? Please advise. Thanks, Nick

Mozilla NSS / OpenLdap 2.4.23 cert not readable?
by Aaron Bennett 16 Dec '11

16 Dec '11

Hello, I'm trying to grok Mozilla NSS prior to deploying Openldap 2.4.23 on RHEL 6.2. I've been working through creating a self-signed cert and I think I have one that works. At least, if I do: [root@animal ~]# certutil -d /etc/pki/nssdb/ -L Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI its Cu,Cu,Cu animal.clarku.edu p,p,p the its cert is the one I used to sign. If I do: [root@animal ~]# certutil -d /etc/pki/nssdb/ -L -n animal.clarku.edu Then I see a normal looking cert: Certificate: Data: Version: 3 (0x2) Serial Number: 00:96:7c:e7:ea Signature Algorithm: PKCS #1 SHA-1 With RSA Encryption Issuer: "CN=ITS Self Signed" Validity: Not Before: Mon Dec 12 16:01:27 2011 Not After : Mon Mar 12 16:01:27 2012 Subject: "CN=animal.clarku.edu,O=Clark University ITS,L=Worcester,ST= Massachusetts,C=US" Here's what I've got in cn=config: olcTLSCACertificatePath: /etc/pki/nssdb/ olcTLSCertificateFile: animal.clarku.edu If do those commands as the ldap user with sudo -u ldap, I get the same output. I can even run "certutil -V -n animal.clarku.edu -u SR -d /etc/pki/nssdb/" and I get "certificate is valid". However when I start slapd, I get: [root@animal slapd.d]# service slapd start animal.clarku.edu is not readable by "ldap" [WARNING] Starting slapd: [ OK ] What am I missing? Thanks, Aaron --- Aaron Bennett Manager of Systems Administration Clark University ITS

Ldap+Nfsv4+kerberos *nix / *bsd puzzle.
by Harry Coin 16 Dec '11

16 Dec '11

Hello group! Looking for guidance on an ldap+NFS4+Kerberos puzzle in a mixed OS local environment. Simple demo case, four computers on a little net. box 1: Running openlap server, kerberos KDC, kadmin, lets say it's running freebsd, doesn't matter. nfs server & client. box 2: Linux box. nfs server & client. box 3: *bsd/Solaris box. nfs server & client. box 4: misc user box, could be *bsd or *nix. Networking: Nfs4 secured with kerberos. That means No uid/gid numbers on the wire, only user@box. NSS is active on all boxes, reaching out to the ldap server on box 1 for info for what is not in the local passwd file searched first. Popular package X gets installed on box 2 and box 3. Package X is a drop-root privilege package, has its own uid/gid!=0. It is active on the net, might write log files or get data files via nfs on either of the other two computers in the setup. The maintainers for package X in the *bsd world have chosen a different number for the uid / gid for the package X daemon than the maintainers for package X have chosen in the *nix world. Those get written in the local passwd file on each system at package X install / download time. Note: Package X does _not_ get installed on the ldap server box #1, or box #4. There is no entry in the #1 or #4 system's passwd file for nss to find for the daemon associated with package X. nfsuserd via nss must find the package X user in ldap or the files will be unreadable or seem 'owned' by nobody:nogroup on 1 or 4 if say config or log files edited/accessed from there. Puzzle: What should the posixAccount uidNumber and gidNumber value be in ldap for uid=packageXdaemon? Alternatives: 1: Choose no entry, leave it out of the ldap db: PackageXDaemon's files will be owned by nobody:nogroup on box 1. Security Fail. 2: Choose *nix for the uid/gid in the ldap database on box 1. Fail: The files will be stored with a uid/gid that might collide with another account in the passwd database on the *bsd server. 3: Choose *bsd for the uid/gid in the ldap database on box 1: Fail: The *nix user on box 4's nfsuserid will get the bsd uid/gid from ldap which could create files not actually owned by something colliding in the *nix passwd database on box 4. 4: Instead storing all the users once under an ou=Account... create ou=AccountBSD and ou=AccountNix, duplicate the whole account tree but vary the apropos uid/gid pair under each tree with all the other remaining equal, manage collisions when amending the database. Not so pretty. 5: Edit the schema to replace uidNumber and gidNumber with uidNixNumber / uidBsdNumber & etc. for gid. Breaks code expecting standard uidNumber gidNumber in the default ldap schemas. There are so many packages that could be X, you can imagine not wanting to have to qualify and patch all of them to use a common uid/gid number. (And it gets even worse in a mixed nfs3 / nfs4 environment where uid/gid numbers actually go over the wire in some cases, and user@box in others, let's leave that to the side for now). I'm leaning toward #5 to avoid storing all the other account information under two different trees. But I'd prefer a scheme were there is a not-edited standard schema tree stored once under 'ou=Account' but with a different overlay for the uid/gid elements if looked up as AccountNix or AccountBsd. I'm sure someone has done battle with this already, what's the right answer? Thanks Harry Coin

slapdindex
by Allan E. Johannesen 16 Dec '11

16 Dec '11

First, I'm running 2.4.27 A year and a half ago, running 2.4.something-less-than-27, we installed a device which queried LDAP and was causing a load on the ldap servers. I found it was looking for an attribute we didn't have. I indexed the attribute and I believed that the load was reduced. I did not add the objectclass which offered the attribute to our objectclasses. Was I imagining things? Recently, we have another black box that queries ldap. I can't control the attributes which it requests. I added the attributes to the index and ran the slapindex and no new .bdb files were generated, even using the -q -t flags, which claims to truncate a database before scanning for the attribute. That sounded like a way to maybe trick it into making an empty database, but no dice. As an experiment, I ran slapadd to create a new database, with those attributes in the index list. It didn't add any of them, nor did it create that single attribute which I believed I had "fixed" last year. I'm reasonably sure that prior openldap versions of both slapindex and slapadd would create the index for an attribute listed as indexed without it appearing in the data. I'm curious to know if I was wrong that indexing an attribute would speed the search even if the attribute did not appear in the schemas used. Also, does this mean that I have to add whatever schema that new ldap-client black-box wants to search in order to make the index in order to reduce that client's ldap server load? Thanks for any insights.
