with winbind being enabled in nsswitch.conf on an AD DC it is not possible to tell winbind which home directory the users should have. The default is /home/DOMAIN/username.
Setting "winbind nss info = rfc2307" should be supported so that the home directory will be the one configured in AD.
Also something like "template homedir = /home/%u" is not usable. with that setting all users will have the home directory "/home/%u" bevause %u is not being expanded.
Andrew, this probably depends on bug 9898, the fact that smb.conf variables are not evaluated generally in samba 4, right?
The issue is more that we need to replace the winbind implementation. The s4 winbindd just doens't have the code to implement winbind nss info, for example - it is purely RPC based, with an occasional sprinkle of LDAP.
the template homedir stuff does work, but it uses %DOMAIN% not %d (a poor choice in retrospect).
Now we have just one build system, combining the two winbind implementations seems a little more practical, but still a large task.
We use the source3 winbind since 4.2
