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(a)openldap.org
Reporter: goudal(a)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).
