Hi Buchan,
i'm trying to test your script but, it didn't found entries for the query:
# Get databases that have a master
$ldap_message = $ldap{$slave}->search(
base => $monitor,
scope => 'sub',
filter =>
'(&(namingContexts=*)(MonitorUpdateRef=*))',
attrs => [ 'monitorupdateref',
'namingContexts' ]
);
And i have the following replication configuration
syncrepl rid=2
provider=ldap://10.1.1.69:389
type=refreshOnly
#type=refreshAndPersist
interval=00:00:05:00
searchbase="o=test"
filter="(objectClass=*)"
scope=sub
#attrs="cn,sn,ou,telephoneNumber,title,l"
schemachecking=on
bindmethod=simple
binddn="cn=root DN, o=test"
credentials=********
What do you think ? Is it dependent of the replication type (refreshOnly
and refreshAndPersist) ?
Rgds, Bruno.
