Description

When restoring a configuration backup, LDAP dump will not be restored because the action nethserver-directory-restore-ldap will fail in post-restore-config event.

The action can't load the new dump because slapd is still running. The action must use upstart interface instead of the old service command.

Workaround
Stop LDAP then execute the restore:

stop slapd
restore-config
start slapd

Proposed patch:

    ldapmodify  -Y EXTERNAL -f test-ldif
    
  • Restore the config:

VERIFIED

Implementation note: next time, use the NethServer::Service perl module, that abstracts the underlying service manager:

$slapd = NethServer::Service->new('slapd');

$slapd->stop();
# execute slapcat
$slapd->start();
