Webapp.log - log in users

I don’t know which please to write topic is better so i write in this category.

I want to know, because before update i knew when log in users which logging in with Local Authentication Provider.
Now in logs i don’t have any information?
Was it the intended action to not see any information about users logging into the application in the logs?

I think if i don’t have in application information about logged users it is important to know about user logon event in logs.
It should be event about
LDAP Authentication Provider
Local Authentication Provider
