The plan is roughly as follows:

o fleash out jarapac/examples to support a wide range of windows
management functions
o implement NETLOGON api using idlc/jarapac/jcifs
o develop an alternative to NtlmPasswordAuthentication that supports
GSSAPI style credential management and rebuild the jcifs library
around that
o develop jcifs functions that use authentication like NTLM HTTP
Authentication filter and using security token to impersonate web user
to access Windows resources (this will be jcifs 2.0)
o add APIs for workstation management functions to jcifs for manipulating
Windows resources (e.g. adding users, rebooting machines, start/stop

So by this timeline we're looking at between 3 months and never

However, when I "flesh out jarapac/examples" I will no doubt work
out the lsarpc and samr functions necessary to resolve sids and
names. However, reading extended attributes and decodeing/encoding
security descriptors/ACLs/ACEs is NOT rpc/ndr. That's old fashioned SMB
and hand writting marshalling. I'll look into actually getting that to
work though. User requests are largely the driving force for development
around here and you're not the only one looking for ACL control.

Sounds like IAccess.Idl is some kind of COM or DCOM 'I'nterface
definition. We're doing MSRPC only right now. COM/DCOM is build on top
