This bug re-occurred for 3.3.x and above.
The reason is that to change a NT ACL we now have to open the file requesting
WRITE_DAC and WRITE_OWNER access. The mapping from POSIX "w" to NT permissions
in posix_acls doesn't add these bits when "dos filemode = yes", so even though
the permission or owner change would be allowed by the POSIX ACL code, the
NTCreateX call fails with ACCESS_DENIED now we always check NT permissions
first.
Added in the mapping from "w" to WRITE_DAC and WRITE_OWNER access.

+ if ((perms & S_IWUSR) && lp_dos_filemode(snum)) {
+ nt_mask |= (SEC_STD_WRITE_DAC|SEC_STD_WRITE_OWNER);
+ }
}
