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.
