NT ACL support

[Freddy Freeloader <fredddy@cableone.net>]

Can anyone tell me if NT ACL support is compiled into the Debian Samba 
packages? 

I've read the Debian rules file in the Samba source package and see a 
line for ACL support but am unsure if that is Posix ACL or NT ACL. 

Second question is, If NT ACL support is not already compiled into the 
package do I need to recompile the entire package or is there a way of 
just patching the ACL support into my existing installation?

TIA
