RID also does this. You can see in the sid<->id mapping functions in
Andrea, you can look at the common nfsv4 code (source3/modules/nfs4_acls.c)
to see how ID_TYPE_BOTH is dealt with there (for instance
nfs4_acl_add_sec_ace()). Can you perhaps give more details about your ACL
modules (or a link to the source)?
