[midPoint] Some tricky questions about develop connectors. Hello!

[Али Саад]

Hello! Could you please explain the difference between the
setRequired(true) and setCreateable(true) flags when defining ConnId
attributes? 1. If the UID is generated by the target system, should we set
required=false and createable=false? 2. For the Name attribute that
midPoint must send when creating an account — should both flags be set to
true? 3. If an attribute can be provided during object creation but is not
mandatory, should it be required=false and createable=true? 4. Is it
correct that we should never use required=true together with
createable=false? Am I right that required=true means the attribute must be
included in the Set<Attribute> passed to the create() method of the
CreateOp interface? No to other operations. Only for Create? I'm trying to
understand the practical meaning of these flags when designing a connector
schema. 5. Additionally, I’m still confused about how account creation
actually works in practice. For example, if I want to manually set the UID
or other attributes when creating an account — how is this done? Is it
controlled by inbound/outbound mappings, or by the connector schema itself?
It’s quite hard to understand how midPoint decides which attributes to send
during account creation on the first try. (I'm using midPoint 4.9.) 6. And
one last question: what is the purpose of setReturnedByDefault(true)? Is it
true that midPoint simply won’t expect such attributes by default, but it
will still accept attributes marked with setReturnedByDefault(false) if
they are present in the resource response? 7. I would also like to mention
that I created an attribute on the diagram as a string for locking and
unlocking __ENABLE__. Am I correct in understanding that Midpoint will
still create it on the diagram with the type that it defines and
recognizes—that is, as Boolean for special system attributes? According to
the Special-Purpose Attributes table? Thank you very much in advance!
