How to create a system user for Services?

[olimination <ol...@gmail.com>]

Hi,

I have implemented a service and would like to use the new interface method
"resolverFactory.getServiceResourceResolver(params)" for using a proper
service user instead of an administrativeResourceResolver.

I have tried to create such a System User via:

curl -u admin:admin -F:name=myuser -Fpwd=mypwd -FpwdConfirm=mypwd
-Frep:principalName=myuser -Fjcr:primaryType=rep:SystemUser
http://localhost:8080/system/userManager/user.create.html

and:

curl -u admin:admin -F:nameHint=myuser -Fjcr:primaryType=rep:SystemUser
-Frep:principalName=myuser http://localhost:8080/home/users/system/*

but this was somehow not successfull.

With the first curl command I received just a "normal" user with
primaryType = rep:User, but it should be a "rep:SystemUser" as I have
understood the documentation.

With the second curl command I received:

javax.jcr.nodetype.ConstraintViolationException: Property is
protected: rep:principalName = myuser

Is there any way in Sling to create such a System User? How do you get
a Service Resource Resolver instance?

AEM offers here the CRX Explorer tool which offers creation of a
system user, but something similar I haven't found yet in Sling
itself.

Thanks for support,

Oli
