lookup_sid for a domain local group results in SID_NAME_UNKNOWN

[Chere Zhou]

I am not sure whether it counts or not but my domain is in native mode.  I 
want to know what other people's experiences are with domain local groups.

I have a "domain local group" called localg.  sid_to_gid() fails because the 
returned name_type is SID_NAME_UNKNOWN.  I traced it down using gdb, and the 
result from winbindd_request(LOOKUPSID....) is:
      dom_name = "ZHOU", '\000' <repeats 251 times>,
      name = "localg", '\000' <repeats 249 times>, type = 8},
					         ^^^^^^^^	
>From smb.h:
/* SID Types */
enum SID_NAME_USE
{
        SID_NAME_USE_NONE = 0,/* NOTUSED */
        SID_NAME_USER    = 1, /* user */
        SID_NAME_DOM_GRP = 2, /* domain group */
        SID_NAME_DOMAIN  = 3, /* domain: don't know what this is */
        SID_NAME_ALIAS   = 4, /* local group */
        SID_NAME_WKN_GRP = 5, /* well-known group */
        SID_NAME_DELETED = 6, /* deleted account: needed for c2 rating */
        SID_NAME_INVALID = 7, /* invalid account */
        SID_NAME_UNKNOWN = 8  /* oops. */
};

So what SID_NAME_ALIAS is for (comment says local group)?  

Is it safe to just change the above to the following without any other code 
change?
	SID_NAME_LOCAL_GRP = 8,
	SID_NAME_UNKNOWN = 9
