Issue ID: 9337 Summary: Slapd crash with lastbind overlay Product: OpenLDAP Version: 2.4.50 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs@openldap.org Reporter: frederic.poisson@admin.gmessaging.net Target Milestone: ---
Hello,
I have an issue with a 2.4.50 OpenLDAP instance configured with replication (1 master and 1 replica), and when i activate the lastbind overlay. The replica server crash like this : slapd[8433]: segfault at 1d0 ip 000000000049f70b sp 00007f189f7fd1a0 error 4 in slapd[400000+1d8000]
The database is this one with overlay loaded : dn: cn=module{0},cn=config olcModuleLoad: {0}sssvlv.la olcModuleLoad: {1}ppolicy.la olcModuleLoad: {2}syncprov.la olcModuleLoad: {3}lastbind.la olcModuleLoad: {4}pw-sha2.la
dn: olcDatabase={3}mdb,cn=config objectClass: olcDatabaseConfig objectClass: olcMdbConfig olcUpdateRef: ldap://master.server:389/
If i add this configuration it crash : dn: olcOverlay={2}lastbind objectClass: olcOverlayConfig objectClass: olcLastBindConfig olcOverlay: {2}lastbind olcLastBindPrecision: 60 olcLastBindForwardUpdates: TRUE
Does the release 2.5.51 or 2.5.52 could solve this issue ?

Does the release 2.5.51 or 2.5.52 could solve this issue ?
The change log for every release is published on the website:
https://www.openldap.org/software/release/changes.html
Neither 2.4.51 or 2.4.52 had changes related to lastbind.
I would suggest obtaining a full gdb backtrace (thr apply all bt full) from the slapd process when the crash occurs and adding it as an attachment or a comment to the bug.

--- Comment #4 from Frédéric Poisson frederic.poisson@admin.gmessaging.net --- I found why the process crash, i didn't configure chain overlay as mentioned inside slapo-lastbind manual:
" lastbind_forward_updates Specify that updates of the authTimestamp attribute on a consumer should be forwarded to a master instead of being written directly into the consumer's local database. This setting is only useful on a replication consumer, and also requires the updateref setting and chain overlay to be appropriately configured."
Once this is configured all is working as desired.
You can close this ITS

It still shouldn't cause a crash, that's a valid bug. I will leave this open.
