@diegocstn ,

I spent some time looking into this further. From what I can tell, the trouble is in StorageEngine.startSync. requiresAuthPlugin() comes back false and therefore leads to the sync engine to start without auth. That it turn leads to the problems, I mentioned above.

Next I checked why it comes back false and found that in AuthRule.requiresAuthPlugin provider is nil, which is being mapped to false. I stopped investigating there, but there seems to be some sort of logic error here, no race. Either way, I adapted the mapping and everything is working fine now.

@diegocstn This appears to have fixed our sync issues as well. Thank you!
