 ticket: 6920
 subject: Fix old-style GSSRPC authentication
 target_version: 1.9.2
 tags: pullup

 r24147 (ticket #6746) made libgssrpc ignorant of the remote address of
 the kadmin socket, even when it's IPv4.  This made old-style GSSAPI
 authentication fail because it uses the wrong channel bindings.  Fix
 this problem by making clnttcp_create() get the remote address from
 the socket using getpeername() if the caller doesn't provide it and
 it's an IPv4 address.
