Subject: ITS#6980 free the result of SSL_PeerCertificate
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=d944920fd39f78d90995484e3721db5c350bd240;p=openldap

ITS#6980 free the result of SSL_PeerCertificate

In tlsm_auth_cert_handler, we get the peer's cert from the socket using
SSL_PeerCertificate.  This value is allocated and/or cached.  We must
destroy it using CERT_DestroyCertificate.
