r1342: When fixing _lsa_lookupsids in samba3 I wanted to find out the number of SIDs

w2k3 can handle in a single request. With the samba3 client rpc libs I can do
about 21000 SIDs in a single request. test_many_LookupSIDs with 10000 SIDs
fails on the subsequent request with a NET_WRITE_FAULT. Maybe the Samba4 DCE
people want to take a look at this -- I don't see the problem.

Bug fix: SID components should be treated as unsigned when parsing
