Hello, The ITS system is for bug reports, not usage issues. Please direct your questions to the openldap-technical @openldap.org mailing list. In addition the version in use, please note whether you are using standard syncrepl or delta-syncrepl, and any relevant configuration information. I would note that numerous bugs with MMR have been fixed since 2.4.44 and that it is strongly advised to use delta-syncrepl as the replication mechanism if stability is desired.

I encountered a problem. In the openldap HA environment, the update user group found that it was not synchronized to the client in time (8 hosts, 5 stations, 3 syncs, not synchronized, waiting for half an hour to complete synchronization).

(ITS#9051) slapo-accesslog fails to log compare, search

08 Jul '19

Full_Name: Quanah Gibson-Mount Version: 2.4.47 OS: N/A URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.128.44) In testing out various logging scenarios with the accesslog overlay, it has been found that it fails to log certain operations in the underlying accesslog DB. Specifically, it fails to log "reads" or "compare" + "search". It does however log "writes" or "bind". Example configuration: dn: olcDatabase={2}mdb,cn=config objectClass: olcMdbConfig objectClass: olcDatabaseConfig olcDatabase: {2}mdb olcDbDirectory: /var/lib/ldap/accesslog olcAddContentAcl: FALSE olcDbIndex: default eq olcDbIndex: objectClass olcDbIndex: entryUUID olcDbIndex: entryCSN olcDbIndex: reqStart olcDbIndex: reqEnd olcDbIndex: reqResult olcDbIndex: reqDN olcDbMaxReaders: 0 olcDbMaxSize: 5120000 olcDbMode: 0600 olcDbNoSync: FALSE olcDbRtxnSize: 10000 olcDbSearchStack: 16 olcLastMod: TRUE olcMaxDerefDepth: 15 olcMonitoring: TRUE olcReadOnly: FALSE olcRootDN: cn=config olcSuffix: cn=accesslog olcSyncUseSubentry: FALSE olcAccess: {0}to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=extern al,cn=auth manage by * break dn: olcOverlay={0}accesslog,olcDatabase={1}mdb,cn=config objectClass: olcAccessLogConfig objectClass: olcOverlayConfig olcAccessLogDB: cn=accesslog olcOverlay: {0}accesslog olcAccessLogOps: reads olcAccessLogOps: writes olcAccessLogPurge: 1+00:00 1+00:00 olcAccessLogSuccess: TRUE Performing a search in this scenario results in nothing logged. Changing it to "reads" only (no writes), nothing logged Changing it to "bind, search, compare", the bind is logged, but nothing else: root@anvil3:~/accesslog-testing# ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=accesslog -LLL -Q dn: cn=accesslog objectClass: auditContainer cn: accesslog dn: reqStart=20190708222217.000000Z,cn=accesslog objectClass: auditBind reqStart: 20190708222217.000000Z reqEnd: 20190708222217.000001Z reqType: bind reqSession: 1014 reqAuthzID: reqDN: cn=admin,dc=rb,dc=symas,dc=net reqResult: 0 reqVersion: 3 reqMethod: SIMPLE Search is clearly logged at STATS level logging: Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 fd=12 ACCEPT from IP=[::1]:51644 (IP=[::]:389) Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=0 BIND dn="cn=admin,dc=rb,dc=symas,dc=net" method=128 Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=0 BIND dn="cn=admin,dc=rb,dc=symas,dc=net" mech=SIMPLE ssf=0 Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=0 RESULT tag=97 err=0 text= Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=1 SRCH base="dc=rb,dc=symas,dc=net" scope=2 deref=0 filter="(objectClass=*)" Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=1 SEARCH RESULT tag=101 err=0 nentries=2 text= Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 op=2 UNBIND Jul 8 15:22:17 anvil3 slapd[12993]: conn=1014 fd=12 closed

I have modified the patch to work with the recent changes on master, but I did not dig in very deep to understand these changes. So I must admit that these modifications to the patch are completely untested (except the tests in the tests subdir). Things might work better with the 2.4.46/47 patch, if that is an option for your customer. Wrt getting a test-tree, maybe the python script I have in the github repo for the patch can provide one. (https://github.com/hbo/openldap-mdb-deref-problem/blob/master/scripts/write…) I'm of course very interested to keep this patch alive, so if you have details on the segv, please let me know.
