MirrorMode vs MultiMaster Questions
by Ben Rockwood 16 May '11

16 May '11

I'm having some problems understanding the subtleties of MirrorMode vs MultiMaster configurations. Any help with the following questions would be helpful: 1) It looks like the only real difference between a MirrorMode and Multimaster configuration is whether or not the RIDs are different. In MirrorMode both sides have the same rid, in Multimaster they are different. Is that so? 2) Passing through the code, "MirrorMode" is really "Single Master" and MultiMaster is just "not Single Master". But the code path to determine whether it is single master or not confuses me. How does slapd actually determine this? 3) For MultiMaster, the docs show using syncrepl to replicate cn=config and the directory (or directories if you have more than one) independently. Is it really necessary to replicate cn=config if the configuration isn't changing? (What I'm really looking for here is to find out if there is state information in cn=config thats being used or if its simply a good idea to ensure the configs are the same by using syncrepl.) Thanks, benr.

Administrator for groups OpenLDAP with Samba Admins
by Juan Diego Calle 16 May '11

16 May '11

Hi, For weeks I have being reading about openldap, in the mailing lists, etc. Basically I have Samba with ldap and I need a GUI to administrate the users(I can use smbldap-tools and a shell, but not some of the administrators). I installed phpldapadmin, and I can log in with the user "Administrator", but I can change, remove or add any user or anything. I have read about people that have similar configurations to mine and solve this problem. Besides the user interface everything seems to work fine, the machines are logged to the domain, the samba server is a PDC. As far as I understand I need to create an ACL in /etc/openldap/slapd.conf for the group that is going to administrate, and the problem is because I am trying to grant permisions to the Group "Domain Admins", and domain admins is more like samba group. So far I can figure out why is not working the stuff I try, but I dont know how to fix it. It has to do with the objectclass. One of my ideas was to create an extra group, just for administrators, and called something like bofhs. I used this as a reference http://www.openldap.org/faq/data/cache/52.html dn: cn=bofh,dc=mydomain,dc=com,dc=ec cn: bofhs objectclass: groupofNames member: cn=administrator,dc=mydomain,dc=com,dc=ec Can I add something to the "Domain Admins" group so they can change data. But i had problems creating this group, didnt work, in some examples they use ou=Group, I dont understand what the ou thing does. Here is a sample of a backup of the ldap db, dn: dc=mydomain,dc=com,dc=ec objectClass: dcObject objectClass: organization o: Company dc: mydomain structuralObjectClass: organization entryUUID:

pwdInHistory question
by Bidwell, Matt 13 May '11

13 May '11

I'm running OpenLDAP 2.5.24 on 2 servers. I'm trying to enforce some security rules on client machines through the ppolicy overlay. All the lockout stuff works fine. I understand that pwdMinLength will not work by design because the password is hashed. I can't get pwdInHistory to work. If I set it to 5 I clearly see 5 pwdHistory entries, all hashed {crypt}, but I can go back and forth between two passwords without it rejecting them for being reused. My current theory is that it's not looking at the actual password to prevent reuse, but the hashed password, which is not going to be the same. Should it be working? Follow up question, shouldn't the password be stored {SSHA} and not {CRYPT} by default? Just to be clear, the password is being set on the client machine using passwd, not on the servers running OpenLDAP. Matt

Getting more info from ldap_auth in case of a quiet failure?
by a z 12 May '11

12 May '11

Hi everyone, I am definitely new to the list, openLDAP, Ldap in general, nssswitch, shadow, samba etc, but heck, we all have to start somewhere. Not really -that- new to application code, but yeah, I'm kinda young and working at an amateur/unemployed small business level, so by default yeah .. technical noob alert... I am having problems finding out why domain login is failing: Up until now I have had pretty good luck being able to figure out how to, for example, Get Ldap and nsswitch running well enough that ldap authenticates my ssh sessions against shadow.. Get a valid sambaSID or objectClass: sambaSamAccount into an ldif without relying on the smbldap_tools library, or writing new acls to put the samba domain admin in a different ou=. (This is why I am trying to work around smbldap_tools, of course I could probably change the UID) I have been through slapd.conf loglevel -1 all day long watching it request attributes that weren't in the ldif, I cannot see yet where in smbldap_tools it decides it needs root's uid, but it goes ahead and uses it to write updates even though there is another user with write access to the right attributes) I can join windows machines to the samba workgroup MYDOMAIN, and be given an opportunity to login to the samba server, so despite the weird unupported things I do, perhaps senselessly, I -think- I have the premise correct.. So I think this is failing on a bdb_index_read: failed (-30988) report. If anyone is still with me, thanks a ton. Before I go nuts enough to post the parts of slapd logging output I am pretty sure are okay, this is what the probable problems are: It just seems that uid=testuser and objectClass=sambaSamAccount should match this con=1011 string and the next time it fails it should be for the next problem Ill have, and not this one. May 14 00:13:34 localhost slapd[30055] => conn=1011 op=3 SRCH base="dc=MYDOMAIN,dc=com" scope=2 deref=0 filter="(&(uid=testuser)(objectClass=sambaSamAccount))" . . . May 13 00:13:34 localhost slapd[30055]: => slap_access_allowed: search access granted by read(=rscxd) May 13 00:13:34 localhost slapd[30055]: => access_allowed: search access granted by read(=rscxd) May 13 00:13:34 localhost slapd[30055]: search_candidates: base="dc=MYDOMAIN.dc=com" (0x00000001) scope=2 . . . May 13 00:13:34 localhost slapd[30055]: <= bdb_index_read: failed (-30988) and of course, the ldif I think it should be matching: dn: cn=testuser,ou=People,dc=MYDOMAIN,dc=com changetype: add objectClass: inetOrgPerson sn: testuser uid: testuser sambaSID: S-1-5-21-28598429-1396753209-3957328313-513 objectClass: sambaSamAccount sambaDomainName: MYDOMAIN Again, thanks. I look forward to seeing the list traffic every day, and yet more slapd -1 logs -- ⎼⎺⎺├@┼␊├├≤-␍⎼␊▒␍:/␤⎺└␊/⎼␤⎺#

Suitability of LDAP as DNS backend - PowerDNS LDAP backend moving to unmaintained status
by Nick Milas 12 May '11

12 May '11

Hi, We've been using for several months PowerDNS Authoritative Server v9.22 with LDAP backend (simple mode), using OpenLDAP (v2.4.22) for hosting our organization's domains (and reverse zones) and it has been working fine (low query times, reliable etc.) so we enjoy having all our organization's data stored/maintained in the same DIT in LDAP. However, as PowerDNS Authoritative Server is preparing for the next version (3.0), it seems that the LDAP backend will be unmaintained (see: http://mailman.powerdns.com/pipermail/pdns-users/2011-March/007547.html) as the LDAP backend developer is no more working on it (see: http://www.mail-archive.com/pdns-users@mailman.powerdns.com/msg03625.html). It has been alleged (see ref. above) that "We don't think that LDAP is a particularly good or interesting place to store DNS data. It will for example have big problems with PowerDNSSEC because of lack of ordering." Moreover, PowerDNS LDAP backend (although current open bugs are very few and of relatively low severity) lacks features (e.g. Notify, which we implement using custom script, cron and notify-dns-slaves, see: http://mailman.powerdns.com/pipermail/pdns-users/2010-October/007109.html) and is not being evolved any more. Additionally, LDAP/database backend projects for BIND9 (SDB and DLZ) do not seem very well maintained either. In any case we prefer PowerDNS approach where backend implementation is cleaner and direct. So, my questions: * From the above and your experience, do you consider LDAP should not be preferred as DNS backend? * Should LDAP be avoided as a DNS/DNSSEC backend? * Would any companies / developer(s) from the OpenLDAP world - perhaps already using or interested in using DNS with LDAP backend - would be willing to devote some time to fix a couple of small bugs and keep the very well-designed and developed PowerDNS LDAP backend in shape? We could even start some community donation effort (to support this development), but I don't know if there is sufficient usage/interest in the LDAP backend that would generate enough funds. In essence, should we drop LDAP as a DNS Record datastore, due to the lack of a properly maintained backend and/or unsuitability for (e.g. DNSSEC) evolution, or you think there IS interest for the maintenance / evolution of the LDAP backend by the OpenLDAP developers/community (even by becoming more openldap-oriented rather than being cross-platform)? Best Regards, Nick

Xymon syncrepl monitoring
by Johan Karlsson 12 May '11

12 May '11

Hi! While looking for OpenLDAP monitoring solutions, i found Buchan's Xymon/Hobbit script at http://staff.telkomsa.net/~bgmilne/xymon/ol/ I saw some previous discussion about it on this list so I thought I'd give it a shot. I'm wondering how it determines a syncrepl slave, cause when I added the test in Xymon on my syncrepl slave I get "Not a syncrepl slave". The graphs and counters are working though. Regards, Johan

Search by customized attribute in OpenLdap
by JOSE L MARTINEZ-AVIAL 11 May '11

11 May '11

Hi, I've installed OpenLdap, and defiened the following schema: attributetype ( 1.2.840.113556.1.4.221 NAME 'sAMAccountName' SYNTAX '1.3.6.1.4.1.1466.115.121.1.15' SINGLE-VALUE ) objectclass ( 1.2.840.113556.1.5.6 NAME 'securityPrincipal' SUP top AUXILIARY MUST (sAMAccountName ) MAY (mail)) I've created an entry as follows: dn: cn=John Smith,ou=External Users,dc=xxx,dc=yyy,dc=com cn: John Smith objectClass: person objectClass: securityPrincipal mail: test(a)test.com sn: Smith userPassword: myPassword sAMAccountName: smith Then I try to get the entry looking for (sAMAccountName='smith'), but it doesn't work. If I look for (cn='John Smith') it founds the entry. So what do I need to do in order to be able to search by sAMAccountName? Thanks Jose

Sorry for the spelling mistake using /usr/local/libexec/slapd -s 256 -h "ldaps:///" And getting the error "daemon: TLS not supported (ldaps:///)" is syslog, I have searched mailing list, the one possible reason mentioned was "openldap is not compiled with TLS support" but I have verified this using ldd. ldd /usr/local/libexec/slapd linux-vdso.so.1 => (0x00007fff1f7ff000) libdb-4.7.so => /usr/lib/libdb-4.7.so (0x00007f80960b4000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f8095e98000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x00007f8095c7e000) libdl.so.2 => /lib/libdl.so.2 (0x00007f8095a7a000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f8095843000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f809562c000) libwrap.so.0 => /lib/libwrap.so.0 (0x00007f8095423000) libc.so.6 => /lib/libc.so.6 (0x00007f80950c2000) /lib64/ld-linux-x86-64.so.2 (0x00007f8096428000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f8094ea9000) I'm not sure whether the problem in certificates could be the reason for this.
