            Bug ID: 16758
           Summary: nscd incorrectly returns failure for innetgr for
                    netgroup entries with wildcards in them
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nscd
          Assignee: siddhesh at redhat dot com

nscd works correctly when the request in innetgr is a wildcard,
    i.e. when one or more of host, user or domain parameters is NULL.
    However, it does not work when the the triplet in the netgroup
    definition has a wildcard.  This is easy to reproduce for a triplet
    defined as follows:

        foonet (,foo,)

    Here, an innetgr call that looks like this:

        innetgr ("foonet", "foohost", "foo", NULL);

    should succeed and so should:

        innetgr ("foonet", NULL, "foo", "foodomain");

    It does succeed with nscd disabled, but not with nscd enabled.  This
    fix adds this additional check for all three parts of the triplet so
    that it gives the correct result.

Patch coming up
