Package: slapd
Version: 2.4.11-1+lenny1
Severity: important
Hi everyone,
When using ldap with syncrepl and a particular configuration, a consumer
crashes the first time the replication starts on an empty database, with
accesslog and logold enabled on the consumer server.
Here are relevant part of the provider's configuration :
--
serverID 000
databasehdb
# The base of your directory in database #1
suffix dc=domain,dc=com
# Where the database file are physically stored for database #1
directory /var/lib/ldap/domain
na
# Log configuration
overlay accesslog
logdb cn=accesslog
logops writes
logold (objectclass=*)
logpurge 4+00:00 1+00:00
# Replication
overlay syncprov
syncprov-checkpoint 100 10
--
And relevant part of the consumer's configuration :
databasehdb
# The base of your directory in database #1
suffix dc=domain,dc=com
# Where the database file are physically stored for database #1
directory /var/lib/ldap/domain
syncrepl rid=000
provider=ldaps://ldap-master./
type=refreshAndPersist
retry=5 5 300 +
searchbase=ou=x,dc=domain,dc=com
attrs=*,+
bindmethod=simple
binddn=cn=xxx,dc=nautile,dc=nc
credentials=xx
# Log configuration
overlay accesslog
logdb cn=accesslog
logops writes
logold (objectclass=*)
logpurge 4+00:00 1+00:00
-
At the beggining, a slapcat on the consumer gives :
dn: dc=domain,dc=com
objectClass: top
objectClass: dcObject
objectClass: organization
o: domain
dc: domain
structuralObjectClass: organization
dn: ou=,dc=domain,dc=com
objectClass: organizationalUnit
objectClass: top
ou:
With the above configurations and the consumer initialized with this LDIF,
slapd (on the consumer) crashes :
# gdb --args /usr/sbin/slapd -g openldap -u openldap -d sync

I think that slapd crashes because it doesn't find an old value for the
accesslog.
