LDAP Schema Changes During Replication
by Anton Chu 27 Oct '10

27 Oct '10

Hi Everyone, I've setup a basic consumer,provider model replication. I've added a new schema eduPerson to my provider server and now the consumer server cannot replicate. Here's the error I'm getting on my consumer server: Oct 21 22:32:08 webtest110 slapd[31984]: slapd starting Oct 21 22:32:08 webtest110 slapd[31984]: syncrepl_message_to_op: rid=000 mods check (objectClass: value #3 invalid per syntax) Oct 21 22:32:08 webtest110 slapd[31984]: do_syncrepl: rid=000 rc 21 retrying I have delete the eduPerson schema on my provider server, deleted the person (uid=jim) using those attributes in my DIT , and restarted the slapd process on both server but error still persists. Any insights appreciated.

Attribute Aliasing
by Russell Harmon 27 Oct '10

27 Oct '10

I'm trying to reconfigure my existing OpenLDAP server to expose personal information under multiple attributes. I'm doing this so that both Apple's contact application and my custom software will work. I've read about rwm-map in slapo-rwm, but although it makes the new attribute accessible, it hides the old one. I need both the new and old to be accessible. For example: I have an existing attribute for a cellular phone number "cellPhone". I want to make this accessible under both the attributes "cellPhone" and "mobile" Is this possible with OpenLDAP? Thanks Russell Harmon

bindpw in SSHA/MD5/CRYPT/...
by Frederic Hornain 27 Oct '10

27 Oct '10

Dear all, For already few weeks, I search for a mean to have an encypted bindpw password in /etc/ldap.conf on my Fedora Linux Ldap client. OK, I have perfectly understood a simple bind requires that the client has the *cleartext* password. Nonetheless, it seems it exists a SASL method which could permit without using Kerberos to have this functionality. - http://www.openldap.org/lists/openldap-technical/200809/msg00145.html - If someone could give me a hand on that, I would appreciate; Thanks a lot in advance for your time and your help. Best Regards Frederic ;) ----------------------------------------------------- Fedora-ambassadors-list mailing list Fedora-ambassadors-list(a)redhat.com

LDAP Backup and Restore
by Anton Chu 26 Oct '10

26 Oct '10

Hi All, I'm in need of figuring out how I can effectively backup my ldap server then restore it in case of crisis. I have a master and consumer ldap server running in replication mode with latest ldap 2.4 version on ubuntu 10. I have an idea on backup and restore procedures but I need verification. Backup procedures: 1. /etc/init.d/slapd stop 2. tar the following directories /etc/ldap /var/lib/ldap # tar -pczf compressed.tar.gz /etc/ldap/ /var/lib/ldap/ 3. convert the configs and dit to ldif sudo slapcat -n 0 > backup/config.ldif sudo slapcat -n 1 > backup/users.ldif 4./etc/init.d/slapd start Restore procedures: 1. Reinstall a fresh vanilla ubuntu ldap server 2. untar the compessed.tar.gz to original location 3. /etc/init.d/slapd stop sudo slapadd -n 0 -l backup/config.ldif sudo slapadd -n 0 -l backup/users.ldif sudo cp backup/ldap.secret /etc/ldap.secret /etc/init.d/slapd start Just a brainstorm and I'm sure it needs revising. TIA, Anton

ldapsearch problem
by Darouichi, Aziz 26 Oct '10

26 Oct '10

Hi All, I inherited openldap-2.2.13-12.el4. that was built by a vendor few years ago, This is running in a production. I built a new openldap-2.3.43-12.el5_5.2. I run a backup of production LDIF file. Imported to the new openldap-2.3.43-12.el5_5.2. deleted all files from /var/lib/ldap except alock and DB_CONFIG file after I stopped services. I run slapadd -v -c -l backup_filename.ldif -f /etc/openldap/slapd.conf > import.log After the import is done I changed owner to be ldap. I started services. Now when I run a search for users passwords ldapsearch -x -D "cn=company,dc=company dc=edu" -w "Password" userPassword > file.txt This is the output in file.txt : # extended LDIF # # LDAPv3 # base <> with scope subtree # filter: (objectclass=*) # requesting: userPassword # # search result search: 2 result: 32 No such object # numResponses: 1 If I run same in production server I get user's passwords. Thanks

Syncrepl not replicating userPassword
by Robert Klopotoski, Jr. 26 Oct '10

26 Oct '10

Hello, I'm running into a problem with syncrepl that I hope someone can help with. I'm hoping it's a simple config problem. There was another thread similar to this one, and I have tried the solutions and still failed. Running slapd 2.4.11 on both the consumer and the provider. The provider has thousands of records with numerous attributes including 'userPassword'. The consumer got it's start from a direct copy of the database files from the provider. All existing accounts have the userPassword attribute on both the consumer and provider. Any time a new record is added to the provider, it synchronizes all attributes other than the userPassword field. The provider has an account on it "dc=replica,dc=domain,dc=edu" for the syncrepl to use from the consumer. An ldap search to the provider using this account shows that it can see userPassword: ldapsearch -x -LLL -b dc=endicott,dc=edu -W -D cn=replica,dc=endicott,dc=edu returns the dn of dn: uid=112232584,ou=Students,ou=People,dc=endicott,dc=edu including the attribute of: userPassword:: e0NSWVBUfSQxJFZ5TXdTJHJJdS85L0EvWjl6UlZnZ3lKYjNtMjE= The consumer for whatever reason is not adding this attribute to any records it syncs. All other attributes come over fine. If I do a complete cleanout of the consumer and have it start it's database directly from the provider, it does the same thing and pulls over everything but userPassword. The config of the consumer is listed below. Where could the problem lie? Thanks, Rob The config files on the consumer look like this: **** Start slapd.conf ***** include /etc/ldap/schema/core.schema include /etc/ldap/schema/misc.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/endicott.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 256 modulepath /usr/lib/ldap moduleload back_bdb sizelimit 15000 tool-threads 1 backend bdb database bdb suffix "dc=endicott,dc=edu" checkpoint 512 30 rootdn "cn=admin,dc=endicott,dc=edu" rootpw password directory "/var/lib/ldap" dbconfig set_cachesize 0 2097152 0 dbconfig set_lk_max_objects 1500 dbconfig set_lk_max_locks 1500 dbconfig set_lk_max_lockers 1500 index objectClass eq lastmod on access to attrs=userPassword,shadowLastChange by dn="cn=admin,dc=endicott,dc=edu" write by dn="cn=replica,dc=endicott,dc=edu" write by anonymous auth by self write by * none access to dn.base="" by * read access to * by dn="cn=admin,dc=endicott,dc=edu" write by dn="cn=replica,dc=endicott,dc=edu" write by * read index entryUUID eq index userPassword eq syncrepl rid=123 provider=ldap://10.1.55.196:389 type=refreshAndPersist interval=00:00:02:00 searchbase="dc=endicott,dc=edu" scope=sub attrs="*" schemachecking=off bindmethod=simple binddn="cn=replica, dc=endicott, dc=edu" credentials="password" retry="60 +" logbase="cn=accesslog" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" syncdata=accesslog updateref ldap://10.1.55.196 **** end slapd.conf ****

Introducing the slapd kinit module
by Ralf Haferkamp 26 Oct '10

26 Oct '10

Hi, a few days ago I committed the new kinit plugin to the CVS tree. It's sole purpose is to have slapd request a Kerberos TGT and keep it renewed as long as slapd is running. Especially useful e.g. if your syncrepl consumer uses SASL/GSSAPI for authentication (basically all setups where slapd also acts as an LDAP client can benefit from it). So there is no need any longer to use any external tools (cron jobs, whatever) to keep the TGT refreshed. You can find the code in current CVS HEAD inside the contrib/slapd-modules/kinit directory. For details on building the plugin see the README file in the same directory. It should be possible to build the plugin against recent OpenLDAP releases. Currently it only works with the MIT variant of libkrb5, it shouldn't be too hard to add Heimdal support though. I just didn't find time yet to look into that. Feedback is appreciated. For bug reports please use the ITS. -- regards, Ralf SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg)

syncrepl missing deletion records?
by Jorgen Lundman 25 Oct '10

25 Oct '10

Hello list; db-4.8.30.NC openldap-2.4.23 We have on a few occasions come across a syncrepl problem where some deletion records do not happen everywhere. Today I was looking at two such problems; Usually the procedure is to delete the old record, then add a new record. #1: deletion of A records in ou=dns ldapmaster has it deleted. ldapslave03 has it deleted. (syncrepl with ldapmaster) dns02, dns04 has it deleted. (syncrepl with ldapslave03) dns01, dns03 still has the record. (syncrepl with ldapslave03) In detail, from dns03.unix, which now has two records: dn: DNSRecord=A1,DNSHostName=(a),DNSZoneName=customer.com,ou=dns,dc=work objectClass: DNSARecord DNSRecord: A1 DNSHostName: @ DNSType: A DNSIPAddr: zz.yy.xx.ww (new IP in reverse) DNSTTL: 600 structuralObjectClass: DNSARecord entryCSN: 20101021232823.000000Z#000002#000#000000 entryUUID: a43076ee-71b6-102f-95dd-c33ccbc720c3 creatorsName: cn=admin,dc=work createTimestamp: 20101021232823Z modifiersName: cn=admin,dc=work modifyTimestamp: 20101021232823Z dn: DNSRecord=A,DNSHostName=(a),DNSZoneName=customer.com,ou=dns,dc=work objectClass: DNSARecord DNSRecord: A DNSHostName: @ DNSType: A DNSIPAddr: dd.cc.bb.aa (old IP in reverse, should have been deleted) DNSTTL: 600 structuralObjectClass: DNSARecord entryCSN: 20091225133051.000000Z#00000b#000#000000 entryUUID: 77344376-85a5-102e-9deb-dbfa8f00ebbd creatorsName: cn=admin,dc=work createTimestamp: 20091225133051Z modifiersName: cn=admin,dc=work modifyTimestamp: 20091225133051Z #2 was pretty much same situation, except this time only dns03.unix missed the deletion. There is nothing much in the logs on either dns03.unix, nor ldapslave03. But LogLevel is only set to "sync". Is this related to: http://www.openldap.org/its/index.cgi/Software Bugs?id=6059 it is peculiar that it is only occurring on delete records. -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)
