Issue ID: 9754 Summary: segfault after adding olcAccess Product: OpenLDAP Version: 2.6.0 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs@openldap.org Reporter: goudal@enseirb.fr Target Milestone: ---

On a new production server 2.6.0 on ubuntu 20.04 LTS uptodate. After adding an olcAccess attribute I got a segfault. The aclValue added is {9}to attrs=ipbCompteValide,ipbEtendue,mailForwardingAddress by dn.base="uid=cptadmin,ou=people,dc=ipb,dc=fr" write by * read

(the ipbXXX attrs are local ones).

I have tried to add it twice and it did segfault twice.

Here are the last logs for the server (logLevel was on sync).
