Subject: Revert "OpenSSL: Do not accept SSL Client certificate for server"
|
|
|
|
This reverts commit 51e3eafb68e15e78e98ca955704be8a6c3a7b304. There are
|
|
too many deployed AAA servers that include both id-kp-clientAuth and
|
|
id-kp-serverAuth EKUs for this change to be acceptable as a generic rule
|
|
for AAA authentication server validation. OpenSSL enforces the policy of
|
|
not connecting if only id-kp-clientAuth is included. If a valid EKU is
|
|
listed with it, the connection needs to be accepted.
