Synchro Data Source: Deletion rules

[Marah Alh]

Hello Dears,
please your support for below:
I sync LDAP users to iTop every 24 hours using the following command:

php -q synchro_import.php --auth_user="admin" --auth_pwd="admin" --data_source_id=1 --csvfile="Persons.csv"

I want to delete each person who is not present in the last sync.
I tried to use the "Deletion rules", but nothing works. Both the replica and the person remain in iTop.
Here are the configurations I have tried:
First attempt:
Users allowed: Administrators only
Full load interval: 2min 0s
Delete Policy: Delete
Update rules:
Retention Duration: 0s

Second attempt:
Users allowed: Administrators only
Full load interval: 1min 0s
Delete Policy: Delete
Update rules: status:inactive;section:test
Retention Duration: 1min 0s

Third attempt:
Users allowed: Administrators only
Full load interval: 1min 0s
Delete Policy: Update then Delete
Update rules: status:inactive;section:test
Retention Duration: 1min 0s

Is it possible to achieve this using "Deletion rules", or do I need to delete them manually?
