Start with the SNIA CIFS Technical Reference.  That should provide a good
foundation for understanding how ACLs work.  As Mike says, there are some
SMBs that will fiddle Extended Attributes, but I doubt that those will be
enough for full support.  The next thing to read is Luke K.C. Leighton's
book DCE/RPC over SMB. See:  http://ubiqx.org/cifs/References.html for
links.

Note that rumor has it that The Open Group (http://www.opengroup.org/)  
will be releasing a lot of its DCE/RPC code (in C, I believe) under an
Open Source license.  This code is not the same as MS-RPC, but it is close 
enough to be very useful.  Converting it all to Java would be a massive 
task, but the hope is that it will be readable enough that we can get some 
clues.
