OpenLDAP Updating Schema Definition
by Jimmy Liang 24 Apr '08

24 Apr '08

I've read that OpenLDAP supports runtime schema modifications but I can't figure out the extensiveness of this feature. On Sun's page ( http://java.sun.com/products/jndi/tutorial/ldap/schema/object.html under the header "Adding a New Object Class") it's telling me that OpenLDAP does not support this kind of modification. When I try the code on that page, I run into Exception in thread "main" javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 21 - objectClasses: value #0 invalid per syntax]; remaining name '' And in the syslog I noticed this Apr 24 15:38:14 localhost slapd[6532]: daemon: read activity on 12 Apr 24 15:38:14 localhost slapd[6532]: connection_get(12) Apr 24 15:38:14 localhost slapd[6532]: connection_get(12): got connid=14 Apr 24 15:38:14 localhost slapd[6532]: connection_read(12): checking for input on id=14 Apr 24 15:38:14 localhost slapd[6540]: do_modify Apr 24 15:38:14 localhost slapd[6540]: do_modify: dn (cn=Subschema) Apr 24 15:38:14 localhost slapd[6540]: => get_ctrls Apr 24 15:38:14 localhost slapd[6540]: => get_ctrls: oid="2.16.840.1.113730.3.4.2" (noncritical) Apr 24 15:38:14 localhost slapd[6532]: ber_get_next on fd 12 failed errno=11 (Resource temporarily unavailable) Apr 24 15:38:14 localhost slapd[6540]: <= get_ctrls: n=1 rc=0 err="" Apr 24 15:38:14 localhost slapd[6540]: >>> dnPrettyNormal: <cn=Subschema> Apr 24 15:38:14 localhost slapd[6540]: <<< dnPrettyNormal: <cn=Subschema>, <cn=subschema> Apr 24 15:38:14 localhost slapd[6540]: send_ldap_result: conn=14 op=3 p=3 Apr 24 15:38:14 localhost slapd[6540]: send_ldap_result: err=21 matched="" text="objectClasses: value #0 invalid per syntax" Apr 24 15:38:14 localhost slapd[6540]: send_ldap_response: msgid=4 tag=103 err=21 Apr 24 15:38:14 localhost slapd[6540]: conn=14 op=3 RESULT tag=103 err=21 text=objectClasses: value #0 invalid per syntax Apr 24 15:38:14 localhost slapd[6532]: daemon: select: listen=6 active_threads=0 tvp=NULL Apr 24 15:38:14 localhost slapd[6532]: daemon: activity on 1 descriptor Apr 24 15:38:14 localhost slapd[6532]: daemon: activity on: Apr 24 15:38:14 localhost slapd[6532]: 13r Does OpenLDAP allow programmic (hopefully but necessarily Java) schema changes at runtime?

OpenLDAP: slave is not being updated by master and replog is empty
by brad davison 24 Apr '08

24 Apr '08

I am working in a test environment to construct a SAMBA / LDAP domain for windows clients. There is a PDC with OpenLDAP server 2.3.35 and SAMBA 3.026 running on ubuntu server 7.10. The PDC is functioning; I am able to create users and login with them, as well as join workstations to the domain. The slave slapd was populated with an output from an ldif file that was exported from the master via: slapcat -l >> master.ldif I had entered the 'replica' line in the master-slapd, and the updatedn and updateref lines in the slave-slapd as stated in 14.4 in the OpenLDAP 2.3 admin's guide. The 'openldap' user has rights to the replog file. Problem 1) The master (dc01-ubuntu.example.local) is not updating the replog file with either a success or failure. Problem 2) The slave (bdc01-ubuntu.example.local) is not getting updates from the master when changes occur. I am relatively new to LDAP and I might be missing something core. I have the OpenLDAP admin guide printed out and I am referring to it, but I believe I had entered the lines as the book instructed. Attached are my master-slapd.conf and slave-slapd.conf files. Again, this is a test environment for now. I understand the current setup is not secure. What I would like to achieve is a working PDC -> BDC replication. When I start slapd on the master i get:Starting OpenLDAP: slapd slurpd. with no errors. When I start slapd on the slave I get : Starting OpenLDAP: slapd with no errors. master-slapd.conf include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/samba.schema include /etc/ldap/schema/misc.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 0 modulepath /usr/lib/ldap moduleload back_bdb sizelimit 500 tool-threads 1 backend bdb checkpoint 512 30 database bdb suffix "dc=example,dc=local" rootdn "cn=admin,dc=example,dc=local" rootpw 12345 replica uri=ldap://bdc01-ubuntu.example.local:389 binddn="cn=admin,dc=example,dc=local" credentials=12345 bindmethod=simple tls=no replogfile /var/log/replog.bdc01-ubuntu.example.local 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,sambaNTPassword,sambaLMPassword by dn="cn=admin,dc=example,dc=local" write by anonymous auth by self write by * none access to dn.base="" by * read access to * by dn="cn=admin,dc=example,dc=local" write by * read ------------------------- slave slapd.conf include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/samba.schema include /etc/ldap/schema/misc.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 0 modulepath /usr/lib/ldap moduleload back_bdb operation sizelimit 500 tool-threads 1 backend bdb checkpoint 512 30 database bdb ### slurpd updatedn "cn=admin,dc=example,dc=local" updateref ldap://dc01-ubuntu.example.local suffix dc=example,dc=local rootdn cn=admin,dc=example,dc=local rootpw 12345 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,sambaNTPassword,sambaLMPassword by dn="cn=admin,dc=example,dc=local" write by anonymous auth by self write by * none access to dn.base="" by * read access to * by dn="cn=admin,dc=example,dc=local" write by * read ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

noob ldap question
by Nizameddin Ordulu 23 Apr '08

23 Apr '08

Hi All, My apologies in advance if this is not the right place to ask this noob question. I am trying to create an ldap database with base dn: dc=tr,dc=tc. Once created it will be used to store the email accounts like username(a)tr.tc. When I execute the command to modify the dn entry, I get the following error root@nizam-desktop:/home/nizam/Desktop# ldapadd -f user2.ldiff -xv -D "cn=admin,dc=tr,dc=tc" -h 127.0.0.1 -w 1234 ldap_initialize( ldap://127.0.0.1 ) add objectClass: top dcObject organization add dc: tr tc add description: top level of the tr.tc hierarchy adding new entry "dc=tr,dc=tc" modify complete ldap_add: Constraint violation (19) additional info: dc: multiple values provided The user2.ldiff file looks like this: dn: dc=tr,dc=tc objectClass: top objectClass: dcObject objectClass: organization dc: tr dc: tc description: top level of the tr.tc hierarchy dn: cn=admin,dc=tr,dc=tc objectClass: organizationalRole cn: admin description: LDAP Directory Administrator dn: cn=user1,dc=tr,dc=tc objectClass: inetOrgPerson objectClass: inetLocalMailRecipient cn: user1 sn: user1lastname mail: user1(a)tr.tc userPassword: 1234 mailHost: 127.0.0.1 The configuration for the database dc=tr,dc=tc is as follows (part of /etc/ldap/slapd.conf) database bdb suffix "dc=tr,dc=tc" rootdn "cn=admin,dc=tr,dc=tc" rootpw 1234 directory /var/lib/ldap/trtc defaultaccess read schemacheck on lastmod on index cn,sn,st,o eq,pres,sub my OS is Ubuntu 7.10 and i am running slapd installed by the synaptic manager. root@nizam-desktop:/home/nizam/Desktop# uname -a Linux nizam-desktop 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux Can anyone please tell me why I can not add dc=tr,dc=tc?

slapd memory footprint
by Stelios Grigoriadis 23 Apr '08

23 Apr '08

After running some test we observed that slapd is consuming a considerable amount of memory, why is that? We ran one client that retrieved the entire tree (it was pretty small anyway) and 10 other clients that searched for a particular item. Comparing version 2.3.39 with 2.3.32 the footprint increases. From top: 2.3.32: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP CODE DATA COMMAND 6049 root 18 0 221m 4904 2568 S 11.5 0.2 0:33.27 216m 2844 137m slapd 2.3.39: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP CODE DATA COMMAND 13062 ldap 18 0 268m 80m 77m S 14.3 16.2 0:42.27 188m 2892 185m slapd Is this to be expected? By decreasing the cachesize we got: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP CODE DATA COMMAND 22492 ldap 18 0 255m 80m 77m S 14.5 16.1 0:39.01 175m 2892 172m slapd which is still pretty big. The whole ldap tree fits into a 14k large ldif file so the amount of data is not large. Is there any way we can influence the memory footprint (eg. by setting som parameter)? /Stelios

Hi Claus, Thank you for your valuable opinion. I tried to "fix" the syntax problem by removing the _ from the username. It worked! However, I want to use the _ because this is my company's user naming convention. I have to point out that when I ran the early version of OpenLDAP (version 2.2-13), there were no syntax problems when I used the ldif with the nisNetgroupTriple that was defined. I just did a custom build of OpenLDAP (version 2.3-39). Then, I immediately encountered the invalid syntax problem when I triled to load the same ldif. Do you have any thought on the wierd problem?
