(ITS#7498) Openldap syncrepl issue
by arunkumar_1123＠yahoo.com 23 Jan '13

23 Jan '13

Full_Name: Arunkumar shanmugam Version: 2.4.33 OS: rhel5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (203.83.248.32) Hi, I've been having issues with syncrepl in openldap. This is plain syncrepl. I'm not using delta-syncrepl as I run with mirror mode on. I've noticed that when there are a large number of writes on the writemaster (Typically around 10 per second) the data on the readslave goes out of sync with the master, typically having entries which have been deleted on the master. The contextCSNs on both the readslaves and writemaster match eventually, but the data doesn't. I'm running the readslave in refreshOnly mode with an interval of 1 minute. I'm using a reasonably large DB of size ~ 2 GB. I turned on the sync logs and found lots of entries with "nonpresent_callback" and "syncrepl_del_nonpresent". Tested this and found it occurring in both 2.4.29 and 2.4.33 (Latest as of this time), and with BDB 4.2.36 as the backend. I was wondering if anyone has faced similar issues before, and if there exists a solution to this problem. I will send any relevant configuration and log snippets as needed. Thanks

(ITS#7497) ldif_read_record line number overflow

Full_Name: Howard Chu Version: RE24/master OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (78.155.233.73) Submitted by: hyc While trying to load a 150 million entry LDIF file using slapadd, it would finish with no errors but only ~107 million entries were loaded. This turns out to be because at 20 lines per record, the LDIF file contained 3 billion lines, and the line number counter is a signed int. And in slapadd, we have the "jumpline" option to skip some number of input lines, when resuming an interrupted load. The jumpline defaults to 0, if the input line number is less than the jumpline the record is silently skipped. After reading the 2147483647th line of the file, it discards all of the rest until hitting EOF. Will fix this by changing the parameter to unsigned long. This is unfortunately going to require a libldap version bump.

Nodes like this get stored in the database during slapadd when a child entry gets added before its parent; a zero-byte stub is stored as a placeholder for the missing parent. When you ran slapadd you should have seen warning messages about missing entries, telling you that your LDIF is incomplete. We can prevent the SEGV but your database is still invalid because your LDIF is invalid. > mdb = 0x7f760eff4010 > id = 1156449 > cursor = 1156449 > lastid = 18446744073709551615 -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Full_Name: Meike Stone Version: 2.4.33 and git OS: Linux / SLES11 SP2 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.200.138.3) I use a Database with about 1,500,000 entires and 2,5GByte ldif from slapcat.

Re: (ITS#7495) access filter not correctly validated if assertion attribute not requested

Sorry for the confusion caused by editing what I've copied from the real system before which uses a group for several Samba DC instances. In this example the ACL part should be more simple like this: access to dn.subtree="o=example" attrs=sambaNTPassword filter="(organizationalStatus=0)" by dn.exact="uid=samba_dc,o=example" write by group="cn=slapd Admins,ou=groups,o=example" =sw by self =w by * none Ciao, Michael.

(ITS#7495) access filter not correctly validated if assertion attribute not requested

Full_Name: Michael Ströder Version: RE24 6f33e2c OS: Debian Squeeze URL: Submission from: (NULL) (2001:8d8:1fe:1:d6be:d9ff:fe06:a14f) This is tested with RE24 built for Debian Squeeze: It seems that ACLs are not correctly evaluated when processing a search request if the assertion type is not requested in the search request. Example: access to dn.subtree="o=example" attrs=sambaNTPassword filter="(organizationalStatus=0)" by group="uid=samba_dc,o=example" write by group="cn=slapd Admins,ou=groups,o=example" =sw by self =w by * none The following search correctly returns attribute sambaNTPassword of the entry: ldapsearch -LLL -X "dn:uid=samba_dc,o=example" "(&(objectclass=sambaSamAccount)(uid=wtester))" organizationalStatus sambaNTPassword But this search does not return sambaNTPassword: ldapsearch -LLL -X "dn:uid=samba_dc,o=example" "(&(objectclass=sambaSamAccount)(uid=wtester))" sambaNTPassword I cannot find any hint in slapd.access(5) that this is expected behaviour.

As already noted, those links don't provide actual schema definitions, nor do they define the USAGE. We're making a judgement call here with no documentation to support it. We should document why we're defining it this way so we don't have to repeat this conversation again down the road. > > p. > >>> Today I've checked the subschema of a W2K8R2 AD server: >>> I did not find a single attribute type description with USAGE although >>> there >>> were attribute types formally defined in RFCs.
