structure that is more generic than just 'IP/port'. It now passes make test, and has been reviewed and updated by metze. (Thankyou *very* much). This passes 'make test' as well as kerberos use (not currently in the testsuite). The original purpose of this patch was to have Samba able to pass a socket address stucture from the BSD layer into the kerberos routines and back again. It also removes nbt_peer_addr, which was being used for a similar purpose. It is a large change, but worthwhile I feel. Andrew Bartlett
