samba - Aug 2012 - idmap confusion

Three unfathormable questions:
1.
What's the difference between:

idmap_ldb : use rfc2307 = Yes
and
idmap config * : backend = ad

2.
Do the terms in (1) above apply equally to Samba4 beta6 and Samba 3.6.3?

3.
If I specify either in (1) then
idmap config : range = abc-xyz
becomes meaningless.

Cheers,
Steve

It is a samba4 winbind setting, so you need it on the Samba4 AD 
controller only

the correct form is:
idmap config SOMEDOMAINNAME : backend =ad

and instructs the winbind from the samba3 suite to look up the uids gids 
from AD for accounts in SOMEDOMAINNAME

No. With idmap_ad you map all not specifically configured domains using:
idmap backend = tdb
idmap uid = some uninteresting range
idmap gid = some uninteresting range

then for each DOMAIN you want to get the idmap information from the AD, 
you specify:
idmap config INTERESTINGDOMAIN1 : backend  = ad
idmap config INTERESTINGDOMAIN1 : range = first range

idmap config INTERESTINGDOMAIN2 : backend  = ad
idmap config INTERESTINGDOMAIN2 : range = second range

and so on.
