During installing and scheduling connection via DB-links, I've come accross settings permissions for the libraries (DLLs) for the account/group Everyone and account/group ANONYMOUS LOGON. So far, I always thought that with Everyone, every connection/request will have access to the resource. Why do I need to specify anything else (e.g. the Anonymous logon)? Also, what is the difference compared to the guest account if there is any?
I did some research before via search engine, but the Q&A forums I visited, did not bring the relevant explanation - what is what, why do I need this and that and how do they differ. Thanks for the intel.
