LDAP - Samba
by Terry Haley 30 Dec '08

30 Dec '08

Ok, I'm trying to wrangle this under control with this setup I've inherited and have run across a few speed bumps. Here's the state of things as is. I've made a few changes to the setup thinking that I've fixed an issue or two and have in fact only confused myself and possibly my configuration. The downside is that I don't know a few key passwords that was used in the original setup. (yay no overlap with my predecessor). I have a samba server acting as my PDC with an LDAP server used for authentication. Question #1: the password contained within the LDAP directory for my 'admin' account should = the 'rootpw' entry in slapd.conf correct? Question #2: the 'ldap admin dn' entry in my smb.conf file should equal the 'rootdn' entry in my slapd.conf file, afterwhich, this should be updated to samba using smbpasswd -w correct? Question #3: the 'admin users' entry within the smb.conf are the users that allow access to the domain correct? Currently, what I'm working with here is that I don't know the 'admin, samba or the samba-admin' passwords. The samba-admin account is just an LDAP admin account but Not the root account. This should be fixed to the above question 2 yes? I would like to change all of these passwords but am fearful that I could make things worse. Also, regarding the components on my network (machines specifically), will there be an issue if I change the 'samba' account (domain account) password with their ability to connect to the domain?

Constant corruptions
by Jason Voorhees 30 Dec '08

30 Dec '08

Hi there: I'm still having problems with my OpenLDAP 2.3.27 from CentOS 5. I know that index directive in slapd.conf causes the creation of .bdb files in /var/lib/ldap, right? If I have this in slapd.conf: index uid,smtpAuth eq,pres ... so in some moment uid.bdb and smtpAuth.bdb will be created in /var/lib/ldap, right? When I create my ldap tree using slapadd and an LDIF file then several .bdb files get created under /var/lib/ldap, but some other no because of there are no attributes of that type in LDIF file. But when OpenLDAP is already running thanks to a simple search like "(smtpAuth=TRUE)" then slapd tries to create smtpAuth.bdb but that's when it fails. I get this message: slapd[11954]: bdb(dc=redtube,dc=com): /var/lib/ldap/smtpAuth.bdb: Permission denied slapd[11954]: bdb_db_cache: db_open(smtpAuth) failed: Permission denied (13) Does anybody know why slapd isn't able to create new index files? Permissions and ownership are totally correct. Any help? :( P.D.: I'm running openldap in a centos paravirtualized with Xen. It could be this the problem?

Thanks!!! That's it! Like you said, I changed my TLSconfiguration.ldif file to point to "dn: cn=config" and it worked. I've once already seen the olcTLS* in the olcGlobal, however, I am new to LDAP backend database configuration, only used slapd.conf before. Thank you very much for the solution!

TLS config causes Object class violation
by forumuser＠online.de 28 Dec '08

28 Dec '08

Recently I upgraded my Ubuntu Server 8.04 to 8.10 and had to reconfigure OpenLDAP (installed by apt-get) through slapd backend database (I used slapd.config before). I have reconfigured OpenLDAP by "sudo dpkg-reconfigure slapd" and confirmed all prior settings, however the old database was moved to /var/backup/ and a fresh one was generated (please see config tree at the end). The problem is, I get following error message..: ldap_modify: Object class violation (65) additional info: attribute 'olcTLSCACertificateFile' not allowed (even olcTLSCertificateFile, if I leave out olcTLSCACertificateFile... olcTLS* seems "not allowed") ..when I try to configure TLS by ldapmodify: ldapmodify -D cn=admin,cn=config -W -x by entering this: dn: olcDatabase={1}hdb,cn=config changetype: modify add: olcTLSCACertificateFile olcTLSCACertificateFile: /etc/ssl/certs/cacert.pem - add: olcTLSCertificateFile olcTLSCertificateFile: /etc/ssl/certs/servercert.pem - add: olcTLSCertificateKeyFile olcTLSCertificateKeyFile: /etc/ssl/private/serverkey.pem The config tree is as follows (I will change "mydomain" and ACL later): dn: olcDatabase={1}hdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: {1}hdb olcDbDirectory: /var/lib/ldap olcSuffix: dc=mydomain,dc=org olcAccess: {0}to attrs=userPassword,shadowLastChange by dn="cn=admin,dc=mydomain,dc=org" write by anonymous auth by self write by * none olcAccess: {1}to dn.base="" by * read olcAccess: {2}to * by dn="cn=admin,dc=mydomain,dc=org" write by * read olcLastMod: TRUE olcDbCheckpoint: 512 30 olcDbConfig: {0}set_cachesize 0 2097152 0 olcDbConfig: {1}set_lk_max_objects 1500 olcDbConfig: {2}set_lk_max_locks 1500 olcDbConfig: {3}set_lk_max_lockers 1500 olcDbIndex: objectClass eq Here's my "sudo apt-cache show slapd" packet information: Package: slapd Priority: optional Section: net Installed-Size: 3872 Maintainer: Ubuntu Core Developers <ubuntu-devel-discuss(a)lists.ubuntu.com> Original-Maintainer: Debian OpenLDAP Maintainers <pkg-openldap-devel(a)lists.alioth.debian.org> Architecture: i386 Source: openldap Version: 2.4.11-0ubuntu6 Replaces: apparmor-profiles (<< 2.1+1075-0ubuntu4), ldap-utils (<< 2.2.23-3), libldap2 Provides: ldap-server, libslapi-2.4-2 Depends: libc6 (>= 2.4), libdb4.2, libgcrypt11 (>= 1.4.0), libgnutls26 (>= 2.4.0-0), libldap-2.4-2 (= 2.4.11-0ubuntu6), libltdl7 (>= 2.2.4), libperl5.10 (>= 5.10.0), libsasl2-2, libslp1, libtasn1-3 (>= 0.3.4), libwrap0 (>= 7.6-4~), unixodbc (>= 2.2.11-1), zlib1g (>= 1:1.1.4), coreutils (>= 4.5.1-1), psmisc, perl (>> 5.8.0) | libmime-base64-perl, adduser Pre-Depends: debconf (>= 0.5) | debconf-2.0 Recommends: libsasl2-modules, apparmor (>= 2.1+1075-0ubuntu6) Suggests: ldap-utils Conflicts: apparmor-profiles (<< 2.1+1075-0ubuntu4), ldap-server, libltdl3 (= 1.5.4-1), umich-ldapd Filename: pool/main/o/openldap/slapd_2.4.11-0ubuntu6_i386.deb Size: 1466528 MD5sum: 41047db9f250c0e73e2e3c43c5d90f5a SHA1: 4c23c98d55851fef7ec4ff5e4fa8d7cd1c885da9 SHA256: 107e5df3dea5a0571a2f99df1d7c919247a4223a991a99e8393b0915e39f1fc9 Description-de: OpenLDAP-Server (slapd) This is the OpenLDAP (Lightweight Directory Access Protocol) server (slapd).

Named pipe to local ldap slave fails when master is down.
by Jan Hugo Prins 27 Dec '08

27 Dec '08

Hi I've got a strange thing yesterday. The server that is doing my master ldap went down due to some software glitch. Al my MDA's are running there own slave ldap so they don't have to go to the master server, but what surprised me, the slaves didn't want to service anything on there named pipe while the master server was down. Why is this? The MTA's also use the ldap on the MDA's but they didn't have any problem during this master ldap outage. The only difference between the MDA's and the MTA's is that the MTA's connect to ldap with TCP/IP while the MDA's connect to ldap with a named pipe. I use syncrepl for replication. My master server is running version 2.4.12 on Fedora 10. My slave servers are running 2.3.43 on Fedora 7. In the near future I want to make this master server a dual master setup with a different server that I'm currently building. But for now I have just one master. This really breaks my whole anti SPOF setup. Can anyone tell me what is causing this? Greetings, Jan Hugo Prins

CSN too old, ignoring, N-way multi-master replication
by Adrien Futschik 24 Dec '08

24 Dec '08

I'm starting a new thread to make it easier to understand my problem. I'm testing N-way multimaster replication with OpenLDAP 2.4.13. I'm able to successfully import data into an instance and have my two masters to sync correctly but then when I try to add a new entry in one of the two masters, I'm getting strange messages : let's say we have m1 & m2 (m1 & m2 are on the same server): I initial import data into m1, it is successfully imported into m2 (at least it looks like it). Then I'm trying to add an entry on m2 (cn=adrien-externe.futschik(a)edfgdf.fr,ou=personnes,o=edfgdf,c=fr). I'm getting strange message on m1 & m2 : m1 log :(repetitively) [...] Entry ou=administrateurs,o=gazdefrance,c=fr CSN 20081224125950.481561Z#000000#001#000000 older or equal to ctx 20081224125950.481561Z#000000#001#000000 Entry cn=adrien-externe.futschik(a)edfgdf.fr,ou=personnes,o=edfgdf,c=fr changed by peer, ignored syncprov_search_response: cookie=rid=004,sid=002,csn=20081224125950.481561Z#000000#001#000000;20081224130148.522455Z#000000#002#000000 do_syncrep2: rid=005 LDAP_RES_SEARCH_RESULT [...] m2 log : (repetitively) [...] master where I added an entry : do_syncrep2: rid=004 LDAP_RES_INTERMEDIATE - SYNC_ID_SET do_syncrep2: rid=004 LDAP_RES_SEARCH_RESULT do_syncrep2: cookie=rid=004,sid=002,csn=20081224125950.481561Z#000000#001#000000;20081224130148.522455Z#000000#002#000000 [...] Is this a bug ?

Re: Fwd: CSN too old, ignoring - and therefore not syncing
by Adrien Futschik 24 Dec '08

I'm facing a similar problem. I'm testing N-way multimaster replication with OpenLDAP 2.4.13. I'm able to successfully import data into an instance and have my two masters to sync correctly but then when I try to add a new entry in one of the two masters, I'm getting strange messages : let's say we have m1 & m2 (m1 & m2 are on the same server): I initial import data into m1, it is successfully imported into m2 (at least it looks like it). Then I'm trying to add an entry on m2 (cn=adrien-externe.futschik(a)edfgdf.fr,ou=personnes,o=edfgdf,c=fr). I'm getting strange message on m1 & m2 : m1 log :(repetitively) [...] Entry ou=administrateurs,o=gazdefrance,c=fr CSN 20081224125950.481561Z#000000#001#000000 older or equal to ctx 20081224125950.481561Z#000000#001#000000 Entry cn=adrien-externe.futschik(a)edfgdf.fr,ou=personnes,o=edfgdf,c=fr changed by peer, ignored syncprov_search_response: cookie=rid=004,sid=002,csn=20081224125950.481561Z#000000#001#000000;20081224130148.522455Z#000000#002#000000 do_syncrep2: rid=005 LDAP_RES_SEARCH_RESULT [...] m2 log : (repetitively) [...] master where I added an entry : do_syncrep2: rid=004 LDAP_RES_INTERMEDIATE - SYNC_ID_SET do_syncrep2: rid=004 LDAP_RES_SEARCH_RESULT do_syncrep2: cookie=rid=004,sid=002,csn=20081224125950.481561Z#000000#001#000000;20081224130148.522455Z#000000#002#000000 [...] Is this a bug ?

Different shells ¿how to workaround?
by Jordi Espasa Clofent 24 Dec '08

24 Dec '08

Hi all, I'm just learning OpenLDAP; I'm hope it isn't a silly question. I've mounted a OpenLDAP (version 2.4 in a FreeBSD 7.x platform) as account authentication server and all works fine. The clients are FreeBSD and GNU/Linux Debian. One problem I've found is related to loginShell field in posixAccount schema. It's because of when I was setting up the servers, I've configured /bin/csh as the default shell for the users It's ok in FreeBSD clients (csh exists in default instalation), but you get an error when you try to authenticate a Debian client. ¿Why? Simple, the default shell in Debian is /bin/bash, not the defined /bin/csh. Currently, do you have two options to workaround this issue: * install csh in Debian clients and assure that the binary path is /bin/csh * make a symlink /bin/csh which point to /bin/bash At present, I've chosen the second option. ¿Is correct this workaround or maybe I don't know some other obvious method to get it? -- Thanks, Jordi Espasa Clofent
