In 389-ds-base up to version, requests are handled by workers
threads. Each sockets will be waited by the worker for at most
'ioblocktimeout' seconds. However this timeout applies only for
un-encrypted requests. Connections using SSL/TLS are not taking this
timeout into account during reads, and may hang longer.An unauthenticated
attacker could repeatedly create hanging LDAP requests to hang all the
workers, resulting in a Denial of Service.
