Created task in the versionhandler (for adding a extra role to user) fails during the startup because cache is not available but is requested. It causes an exception from Guice caused by the info.magnolia.jaas.sp.ldap.LDAPUserManager that requests the CacheModule.

What happens is that when you add a role to a user, the user is requested through the DelegatingUserManager. This iterates over the available user managers (in keySet order so no speciic order), when it requests the user from the LdapUserManager the usermanager tries to access the cache, which as this is during the startup is not available and cause Guice to throw a ProvisionException which causes Magnolia to stop.
