Audit sessions to Dynamics CRM 4

Question

I'm looking for information about how to audit logins to Dynamics CRM 4. This is an on premise site, and use Active Directory for authentication. I'm currently evaluating two choices:

1- Create a custom http handler and create a handler for begin_session event of HttpApplication class

2- Use a system policy to audit credential validation in Windows.

Is there any other choice? If there's not, which one of this is better?

Answer 1

Normally these two solutions are suggested:
