8000487: Java JNDI connection library on ldap conn is not honoring 
configured timeout

When attempting to connect while using simple auth, we actually perform 
a read. This means that the connection is subject to the read timeout. 
The solution is to alter the readtimeout to the same value as the 
connect timeout for the duration of the auth.

Identical to JDK8:
