What is the difference between Finalize() and Dispose() methods?

1. We got an ADFS server (AD Federation Server)
2. It forwards authentication to 2 ("slave") servers, the company AD / Auth server and a private AD server for extra custom user

var context = new AuthenticationContext(adfsInfo.Authority, false);
var credential = new UserPasswordCredential(adfsInfo.UserName, adfsInfo.Password);
var result = await context.AcquireTokenAsync(adfsInfo.ResourceId, adfsInfo.ClientId, credential);

1. works for user in the company AD server
2. doesn't work for user in our private additional AD server. I got "invalid user or password"
