winbind: Test wbinfo -u with more than 1000 users
winbind asks dcerpc_samr_LookupRids in one batch, where samr.idl has
NTSTATUS samr_LookupRids(
[in,ref] policy_handle *domain_handle,
[in,range(0,1000)] uint32 num_rids,
[in,size_is(1000),length_is(num_rids)] uint32 rids[],
[out,ref] lsa_Strings *names,
[out,ref] samr_Ids *types
);
limiting num_rids to 1000 entries. Test this.
