A socket returned by `createConnectionSocket` here needs to be saved to the
`socket` variable - currently almost all of the tests that are not using a
custom socket factory - fails with:
Caused by: java.lang.NullPointerException: Cannot invoke

at java.naming/com.sun.jndi.ldap.Connection.<init>(Connection.java:238)
