[Flow] Aithentication provider could not be resolved, only in production context

[Christian Loock]

Hi everybody,

I am currently facing some weird issues, when I try to deploy one of our 
new applications to our production server.
I use a custom AuthenticationProvider the extends the TYPO3\LdapProvider 
class, which works great in development context on our dev server, and 
also when i run the app on the production server in development context. 
However, when I set the context to production, I get the following 
exception:

An authentication provider with the name
   "RA\ReleaseManager\Security\Authentication\Provider\LDAPProvider" could
   not be resolved.

I allready checked the file permissions on the Cache folders, and 
noticed, that only Flow_ Classes seem to be cached. If i look into 
Settings.yaml for the production context, I only set the database 
settings inside there, so this cant be it either. Does anybody have an 
idea how this behaviour can be explained that it might be caused by 
using different contexts, when the only difference in settings is the 
database config?

I am really lost here, any help would be highly appreciated.

Cheers,

Chris
