(ITS#9095) back-mdb slapindex missing records
by hyc＠openldap.org 11 Oct '19

11 Oct '19

Full_Name: Howard Chu Version: 2.4 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (84.203.26.174) Submitted by: hyc In back-mdb the entry reindexer operates in batches of 500 entries at a time. (I.e., it commits one LMDB txn for every 500 entries.) But a final txn_commit is missing in tool_entry_close() to flush out the last few entries that were operated on.

(ITS#9094) LDAP server out of memory
by gihanridal8＠gmail.com 09 Oct '19

09 Oct '19

Full_Name: Gihan De Silva Version: 2.4.44 OS: 7.5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (123.231.119.138) Dear Sir/ Madam, We are having two OpenLDAP servers on production with master master data synchronization. We are facing an incident where both servers consume memory upto 99% and LDAP server2 leads to not responding state. As a workaround we have restart both OpenLDAP nodes. However after few days the memory goes high at its peak. There are about 100k+ requests for one LDAP server per day. where both servers are identical in terms of 16 GB RAM, 4 CPUs, CentOS7 OS and LDAP server 2.4.44. We didnt observe any suspiciuos errors in the logs as well. Appreciate your valued consultation and recomendations on this incident for a RCA and a solution. Thank You Regards, Gihan.

(ITS#9091) mdb attribute get mixed up in slapadd continue (-c) mode
by maxime.besson＠worteks.com 08 Oct '19

08 Oct '19

Full_Name: Maxime Besson Version: 2.4.48 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (77.193.139.162) I am attempting to implement the following disaster recovery process: * rm all previous data * run a configuration script (puppet) to recreate a bare-bones LDAP server and DIT * restore a backed-up slapcat dump on top of the freshly installed OpenLDAP server, ignoring duplicates already inserted by Puppet But it seems that when skipping over the existing objects, something goes wrong and causes attributes to get mixed up. But only when certain attributes are present in the existing objects. Here is how to reproduce: slapd.conf: === include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/inetorgperson.schema moduleload back_mdb database mdb maxsize 1073741824 suffix "dc=example,dc=com" directory /tmp === puppet_init.ldif === dn: dc=example,dc=com objectClass: domain dc: example === backup.ldif === dn: dc=example,dc=com objectClass: domain dc: example contextCSN: 20190909094705.796552Z#000000#001#000000 dn: uid=ttully,dc=example,dc=com objectClass: inetOrgPerson uid: ttully userPassword:: c2Nob29uZXI= facsimileTelephoneNumber: +1 408 555 0111 givenName: Torrey cn: Torrey Tully telephoneNumber: +1 408 555 2274 sn: Tully roomNumber: 3924 mail: ttully(a)example.com l: Sunnyvale ou: Human Resources ou: People === When running the following commands: === rm -f /tmp/*.mdb slapadd -f slapd.conf puppet_init.ldif slapadd -f slapd.conf -c backup.ldif === The redundant root object in backup.ldif gets skipped as -c should do, but the attributes from my "ttully" user (and every following object in the ldif dump) end up all mixed up: === slapcat -f slapd.conf ... dn: uid=ttully,dc=example,dc=com objectClass: inetOrgPerson userPassword:: dHR1bGx5 facsimileTelephoneNumber: schooner givenName: +1 408 555 0111 cn: Torrey telephoneNumber: Torrey Tully sn: +1 408 555 2274 roomNumber: Tully mail: 3924 l: ttully(a)example.com ou: Sunnyvale ou: Human Resources ou: People ... === This mixup does NOT happen if: * I import backup.ldif into an empty database * OR I remove "contextCSN" from the backup ldif * OR I use BDB instead of MDB So it seems that my issue is caused by a combination of MDB, skipping existing entries, and having special attributes (contextCSN) in the skipped objects. I was able to reproduce this behavior: * On Debian Buster (OpenLDAP 2.4.47) * On RHEL7 + LTB project RPMs 2.4.48 * Using a git snapshot (3be82f40d5cd4ca050e10859ecb961f28c807c41) with no particular config options * Using cn=config rather than slapd.conf * On a real production system, rather than the simplified version presented here. * Using another "special" attribute such as pwdAccountLockedTime instead of "contextCSN"
