[Samba] winbind/idmap/AD problem?

I'm running 3.0.28a on Ubuntu 8.04 (their package).  I've got security =
ads and idmap backend = ad (smb.conf is posted below). I'm using
libnss-ldap and have ldap in nsswitch.conf (also posted below) and ldap
connected to the AD server.  I have the drive mounted using acl and
xattr_user options in fstab (acl is installed).  I can connect to the
share, I see in the logs that it's picking up the uid and gid from SFU
in AD, however, when I go into the explorer security tab (on the client)
and try to add a user it fails.  I don't get an error message within
windows (the user adding another user is the owner of the file/folder),
the user just disappears from the list as it refreshes!  On the server
I'm seeing a lot of this in log.winbindd-idmap

  ADS uninitialized

Now I don't know if this is related, but if I wbinfo -n wsd\\rippls I
get a long SID number, if I do wbinfo -s [same SID number] I get wsd
\rippls.  However, if I do wbinfo -U [uid for same user] I get a
different SID from before!

I'm trying very hard this summer to make this work so I can retire our
MS file server, so any help would be appreciated.  I tried this
initially in Etch, but I that version wasn't handling the connection to
AD for nss and winbind very well at all, hence I'm trying in Ubuntu.
