I don't like these two...

Add nscd_client_domain to the daemon_domain call for smbd

Samba's currently not allowed to delete logs - it seems this was
done on purpose. Why, I'm not sure - so you can't erase valuable
audit trail I suppose...


By the way, notice how samba doesn't use standard log macros for
this (append_logdir_domain). The only reason for this appears to 
be that the type is shared across multiple types. This is not a very
good reason. IMHO we need to change all those log/var/etc macros 
to address this issue. If you look at home_macros.te you'll see one
(rather ugly) way to address this - separate macro in one declaration
part, and another "access" part.
