Update CAPsMAN passphrase

RouterOS Scripting
1

Hi guys,

I try to change pass phrase in CAPsMan by API. Command in CLI working fine:

/caps-man security set guess-security  passphrase=333333333333333

so I call the same over API:

$mikrotik->write('/caps-man/security/set', false);
$mikrotik->write('=name=guess-security', false);
$mikrotik->write('=passphrase=333333333333333');

router return !done, but nothing changes.
Is there any other way to change passphrase by the API?
