On the OS level everything works flawlessly (without using winbind).
Login upon first try, kerberos ticket properly issued, uid/gid set to
the numbers provided from the LDAP (Samba DC) backend. 
I would simply expect smbd to use the uid/gid provided by whatever
backend if present in the user's data.
The only thing not working as expected is when I try to connect to a
share provided by smbd running on that machine. That takes two login

Well, yes - assuming AD is just a fancy way to bundle LDAP+Kerberos ;-) 
You can just use about any LDAP tools to retrieve information from a
Samba AD DC and see all attributes set.

No, I'm not using nslcd. Solaris provides it's own set of tools and
clients for various name service backends. Usually the different
backends are accessed through nscd which deals with the clients for the
 different types of name services.

I already have 

       idmap config MD-DZNE:backend = ad
       idmap config MD-DZNE:schema_mode = rfc2307
       idmap config MD-DZNE:range = 10000-999999

       winbind nss info = rfc2307
       winbind use default domain = yes
       winbind enum users = Yes
       winbind enum groups = Yes

in my smb.conf and winbindd is running. 
I just don't see why I should third party stuff to do user
authentication on the OS side when the system's own mechanisms work
just fine. And as long as I haven't figured out, why wbinfo doesn't
return the id's I assigned to the users I'd rather not try to use
winbind for unix logins on that machine.

markgrafb.niihau ~ > wbinfo -i markgrafb
markgrafb.niihau ~ > getent passwd markgrafb
markgrafb:x:10058:10001:Bernd Markgraf:/home/markgrafb:/usr/bin/tcsh

I would expect to see the same output from both commands.
