I think you may be referring to Leader and Clerk Resources (https://lcr.lds.org
), not the Directory app (https://lds.org/directory/
). The Directory app does not show birthdays or have a Reports tab; however, you may be able to see all of the Beehives in this app. Member can control their privacy options, and the default varies by country. For example, in USA, the default would be for all ward members to see other ward members, but if you're in the EU, the default is probably private for everyone. I don't know what the defaults are for other areas of the world.
If you are trying to use Leader and Clerk resources (I think that's what you're using), then you may get more assistance by posting your question in that forum (see https://tech.lds.org/forum/viewforum.php?f=112
). This forum is dedicated to the Directory app, which functions differently.
