--- Comment #1 from Howard Chu hyc@openldap.org --- (In reply to Ondřej Kuzník from comment #0)
if you run the following modify against slapd (notice the olcDbMultival data is wrong), slapd aborts in mdb_cf_cleanup->mdb_attr_dbs_open when cleaning up the olcDbIndex changes:
dn: olcDatabase={1}mdb,cn=config changetype: modify add: olcDbIndex olcDbIndex: member eq olcDbIndex: memberof eq
add: olcDbMultival olcDbMultival: member,memberOf 5,15
Unable to reproduce, need the slapd config at least.
