Thanks for your suggestion. Sadly, as we're on Solaris, we immediately hit the following problem when testing on our test system:
With logs such as:
[2012/07/19 22:04:13.304260, 3] smbd/vfs.c:128(vfs_init_custom)
Initialising custom vfs hooks from [/[Default VFS]/]
[2012/07/19 22:04:13.305462, 0] lib/util.c:1117(smb_panic)
PANIC (pid 21463): sys_setgroups failed
[2012/07/19 22:04:13.305769, 0] lib/util.c:1271(log_stack_trace)
unable to produce a stack trace on this platform
[2012/07/19 22:04:13.306084, 0] lib/fault.c:358(dump_core)
Can not dump core: corepath not set up
Although our systems do have the patched kernel, we're unsure of going down the winbind route as we've had some bad experiences when using winbind in the past, and we'd probably have to reboot the live system after changing /etc/system. We'll keep investigating to see if we can get it to work for us.

Try running winbind. You don't need id mapping or nsswitch,
but winbind serving as a proxy to the DC might help you.
