Subject: [PATCH] End connection on KDC_ERR_SVC_UNAVAILABLE
|
||
|
|
|
||
|
|
In sendto_kdc.c:service_fds(), if a message handler indicates that a
|
||
|
|
message should be discarded, kill the connection so we don't continue
|
||
|
|
waiting on it for more data.
|
||
|
|
|
||
|
|
ticket: 7899
|
||
|
|
(cherry picked from commit ca80f64c786341d5871ae1de18142e62af64f7b9)
