New Revision: 204278
URL: http://svn.freebsd.org/changeset/base/204278
Log:
Don't inforce an upper bound on kern.ngroups. The INT_MAX-1 limit was
too high due to several overflows. The actual limit is somewhere in the
neighborhood of INT_MAX/4 on 64-bit machines, but most systems could not
support such a limit due to a lack of memory and the cost of duplicate
credentials.
