[Samba] Proper manner to join second DC

[Bob Wooden]

In re-reading the "Joining_a_Samba_DC_to_an_Existing_Active_Directory" 
Sambawiki page.

Is it no longer necessary to manually delete all *.tdb and *.ldb 
database files from the soon to be joined (second) DC prior to joining?

Are these database file deletions NOW "handled" by any one of the "three 
authentication methods you can use" to join the second DC?

(With newer versions come various improvements . . . what has happened 
with regard to this joining step?)
