Avoid unexistent user queries
by Jordi Espasa Clofent 20 Aug '09

20 Aug '09

Hi all, I'm using OpenLDAP as account server. In the server I see a lot of queries from inexistents users in LDAP: filter="(&(objectClass=posixGroup)(|(memberUid=ivan)(uniqueMember=uid=ivan,ou=sat,ou=tecnic,dc=cdmon,dc=com)))" filter="(&(objectClass=posixAccount)(uidNumber=900))" filter="(&(objectClass=posixAccount)(uid=postfix))" filter="(&(objectClass=posixAccount)(uid=postfix))" filter="(&(objectClass=posixAccount)(uid=postfix))" filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=nobody))" gidNumbercn filter="(&(objectClass=posixAccount)(uid=postfix))" gidNumbercn filter="(&(objectClass=posixAccount)(uidNumber=125))" gidNumbercn filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=xatlantax))" gidNumbercn filter="(&(objectClass=posixAccount)(uidNumber=900))" gidNumbercn filter="(&(objectClass=posixAccount)(uid=cetr))" gidNumbercn filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uidNumber=900))" gidNumbercn filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=root))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" filter="(&(objectClass=posixAccount)(uid=www-data))" I don't understand why because of users as '900, postfix, root, www-data' don't exists as users in LDAP server. On the other hand, the user 'ivan' exists and you can see the difference in the log record. ¿Where is the problem? Maybe in my /etc/nsswitch.conf of LDAP clients? # cat /etc/nsswitch.conf passwd: files ldap group: files ldap shadow: files ldap sudoers: ldap hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis Taking for example the common 'www-data' user query, I see in the LDAP client the next: # cat /var/log/auth.log | grep apache Aug 20 01:20:30 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:20:30 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:20:30 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:20:30 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:20:58 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:02 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:04 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:04 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:05 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:05 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:05 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:05 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:06 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:48 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:49 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:50 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:50 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:50 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:50 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:50 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:21:59 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:00 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:00 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:03 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:05 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:07 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:07 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:24 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:24 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:24 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ Aug 20 01:22:25 xen-ad0010 apache2: nss_ldap: reconnected to LDAP server ldap://192.168.10.1/ ¿Why Apache2 tries to connect to LDAP (192.168.10.1)? ¿How I can avoid it? -- Thanks, Jordi Espasa Clofent

using ldapsearch to get whole data
by mukim pathan 20 Aug '09

20 Aug '09

Hi, I am unable to use slapcat to get whole database into a ldif file because I have a 32 bit machine which cannot write file having size more than 2 GB. So I am looking for alternate ways to get full database into ldif file. So please tell me if there are any alternate ways to do this. I am using openldap-2.4.16 with BDB-4.5 Regards, Mukim Pathan

Hi - I have question regarding the HA, configured LDAP Multimaster Replication (Openldap 2.4.17 & BDB 4.6.21 ) I can see the Users data in both Server1 and Server2. When I turned off the server2 the users are not getting authenticated through Server1. It always getting authentication through Server2. I would appreciate your valuable suggestion! Thanks, PB

ldap_add: Already exists (68) errors when testing multi-master sync replication
by Barry Colston 19 Aug '09

19 Aug '09

While testing sync replication, I encountered a situation in which a previously deleted DN cannot be added again because the ldapadd command receives a 68 error code. If I perform an ldapsearch command for the DN, the DN is not found. If I try to add the DN, the add fails with a 68 error code. If I perform a slapcat command for that DN, slapcat displays the record. I have removed all BDB index files and rerun the slapindex command, but the DN is still not found with the ldapsearch command and fails to be added because of a 68 error code. 1 reason I can think of is that deleting a DN does not physically delete the record, but flags the DN as being logically deleted. This condition does not happen all the time, but it does happen eventually after I have been adding, modifying, and deleting records for approximately 15 minutes. I'm running openLDAP 2.4.17 with BDB 4.6.21 (and have not applied the 4 BDB patches). Running sync replication with 2 masters defined in mirror mode using refreshandpersist; issuing LDAP commands against only master slapd #1. Barry Colston

[PROBLEM] delta-syncrepl, accesslog and filters
by mkappe 19 Aug '09

19 Aug '09

Hello, I use openldap 2.4.16. I configured 2 servers using syncrepl. I would like to sync only a DIT fragment and so i put these lines in the consumer slapd.conf file: syncrepl rid=111 provider=ldaps://mydomain.it<http://ldapstudenti.cca.unipd.it:12315/> type=refreshAndPersist searchbase="dc=mydomain,dc=it" filter="(&(objectClass=MyClass)(Email=true))" attrs="Username,UserStatus,UserExpireDate" schemachecking=off bindmethod=simple binddn="cn=reader,dc=mydomain,dc=it" credentials=xxxxxx retry="60 +" When i try to get out of the scope an entry (setting its attribute 'Email' = false) in the producer, i see that the same entry is removed from the consumer. Everything works fine if i don't activate delta syncrepl mode using accesslog overlay. If i do that, every changes in the producer is propagated to the consumer even if the entry is out of the scope defined in the consumer. How can i configure delta syncrepl (with accesslog) for sync only a DIT fragment? My producer (delta-syncrepl mode) slapd.conf is: moduleload syncprov.la ####################################################################### # ACCESSLOG database definitions ####################################################################### moduleload accesslog.la database bdb suffix "cn=accesslog" rootdn "cn=accesslog" directory /openldap/data/accesslog index default eq index entryCSN,objectClass overlay syncprov syncprov-nopresent TRUE syncprov-reloadhint TRUE ####################################################################### # BDB database definitions ####################################################################### # RAMO LOCALE: database bdb suffix "dc=mydomain,dc=it" rootdn "cn=manager,dc=mydomain,dc=it" rootpw xxxxxxx directory /openldap/data index objectClass,uid eq index entryCSN eq index entryUUId eq index Email pres,eq ####################################################################### # Syncrepl - Sincprov ####################################################################### overlay syncprov syncprov-checkpoint 100 1 syncprov-sessionlog 100 overlay accesslog logdb cn=accesslog logops writes logsuccess TRUE logpurge 00+01:00 00+00:15 ####################################################################### # ACL ####################################################################### access to dn.subtree="dc=mydomain,dc=it" attrs="userPassword" by anonymous auth by self write by * search access to * by dn.base="cn=reader,dc=mydomain,dc=it" read by * break My consumer (delta-syncrepl mode) slapd.conf is: ####################################################################### # BDB database definitions ####################################################################### # RAMO LOCALE: database bdb suffix "dc=mydomain,dc=it" rootdn "cn=manager,dc=mydomain,dc=it" rootpw xxxxxxx directory /openldap/data index objectClass,uid eq index entryUUID,entryCSN eq index Email pres,eq ####################################################################### # DELTA-SYNCREPL ####################################################################### syncrepl rid=005 provider=ldaps://mydomain.it:123 type=refreshAndPersist searchbase="dc=mydomain,dc=it" filter="(&(objectClass=myClass)(Email=true))" logbase="cn=accesslog" syncdata=accesslog schemachecking=off bindmethod=simple binddn="cn=reader,dc=mydomain,dc=it" credentials=xxxxxx retry="60 +" updateref ldaps://mydomain.it:123 ###################################################################### # ACL ###################################################################### access to dn.subtree="dc=mydomain,dc=it" attrs="userPassword" by anonymous auth by self write by * search access to * by dn.base="cn=reader,dc=mydomain,dc=it" read by * break Thank you!

Missing UUID for entry being copied by syncrepl to secondary ldap
by Robert Hanson 19 Aug '09

19 Aug '09

(Openldap 2.4.17; BDB 4.5) I have a database that I have set up in non-replicated mode (no syncrepl setup). Now, I've added a second node in a multi-master configuration. When I start slapd on the second node, syncrepl starts up and tries to copy data to the second node. I've stepped through the syncrepl code on the master using a debugger, and it is clear that onespecific node (from the set of nodes in the master database is being queued up and sent to the secondary) has a UUID entry of length 1, and a value of "0". When that node is sent to the secondary, it is treated as if it has no UUID, which is caught by an assertion. This causes the slapd on the secondary to exit. Why is the node on the primary missing the UUID? Is there some code I can trace through to determine this? Is there a way to add the UUID to the entry? Or is there a way to patch the syncrepl code to avoid sending the node that is missing the UUID?

How to get some overlays?
by ulises gonzalez 18 Aug '09

Hello I'm begining to use Openldap, I'm using the version 2.4.11 which comes precompiled with Debian Lenny, the problem is that each time I try to load some overlay the logs saids...

Aug 17 14:49:08 ldap slapd[5040]: connections_destroy: nothing to destroy. And Openldap doesn't start, I've been searching in the Openldap website but I haven't found any link to download so my question is where I can get overlays? I need exactly unique and syncprov overlays.

Regarding using ldap_modif_ext_s for modifying all users globally in AD?
by Santosh Kumar 17 Aug '09

17 Aug '09

Hi Everyone, Please help us to modify all users under "users" container. could modify for individual user entry for attributes. Is the the user_dn parameter specified correct? Will the ldap_modify_ext_s supports the globally users entry modification? 1) Modify the user "tetsuser5" char *user_dn = "cn=testuser5,cn=users,dc=kpvmpdc,dc=com" if (ldap_modify_ext_s(ld, user_dn, mods,NULL,NULL) != LDAP_SUCCESS) { ldap_perror( ld, "ldap_modify_s" ); exit(EXIT_FAILURE); } ->Works 2)To modify users globally, used : char *user_dn = "cn=users,dc=kpvmpdc,dc=com" that gives error ldap_modify_s: Object class violation (65) additional info: 0000207D: UpdErr: DSID-03150F9C, problem 6002 (OBJ_CLASS_VIOLATION), data 0 Thanks in advance. Regards Santosh
