I'm trying to sync service user properties from my application back-end into POA but getting this error:

    code: 403
    type: "Poco::Exception"
    message: "userId, login and password properties must not be modified"
    error: "ApplicationUnknownError"

Why is it not allowed to change login and password?


Service user is a POA entity, it can have various services: an Exchange/Qmail mailbox or be propagated into any number of APS packages.

There are two reasons for prohibiting to change service user password and login:

  • changing such critical properties as login and password would mean that all application that do not listen for service user changes would be broken.

  • service user might not want an APS application to be permitted to change his login and password, if used unwisely he may be locked out of all his services
