[Samba] username map Solaris 10 11/08 using Sun DS 5.x ldap for authentication

[Andrew Chaplin]

Here's the configuration:
	OS: Solaris 10 11/08
	OS Authentication: Sun Directory Server 5.x
	Samba: v3.0.32 included with Solaris 10 11/08
	Samba auth: Windows 2003R2 AD

Using a Windows XP client authenticated against AD mounting of home 
directories works fine and I'm able to perform create/modify/delete 
ops on files/directories in the home directory and files/directories 
which are created have the proper uid/gid associated with the user.

If I try to modify the permissions for a file/directory from XP, samba 
complains about not being able to map a SID to a uid/gid.

Windows 2003R2 AD has the RFC2307 schema preloaded.  If I populate 
user accounts with their respective uid/gid, will that resolve the 
mapping error?  Am I going to run into problems with winbind?

Are there other options?

Note that it is essential that LDAP and AD maintain consistent uid/gid 
per user/group.
