These patches are to address an issue unpacking a very large winbind.wbint_Principals array (100,000). We need the NDR_TOKEN_MAX_LIST_SIZE value exposed as otherwise a well-meaning incrase of this value would invalidate the test. BUG: https://bugzilla.samba.org/show_bug.cgi?id=14710 Signed-off-by: Andrew Bartlett <abartlet@samba.org> Reviewed-by: Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
