The [method documentation of com.sun.jndi.ldap.Connection::createSocket](https://github.com/openjdk/jdk/blob/3ebe6c192a5dd5cc46ae2d263713c9ff38cd46bb/src/java.naming/share/classes/com/sun/jndi/ldap/Connection.java#L281) states: "If a timeout is supplied but unconnected sockets are not supported then the timeout is ignored and a connected socket is created."

If a SocketFactory would not support unconnected sockets, it would likely throw a SocketException in [SocketFactory::createSocket()](https://github.com/openjdk/jdk/blob/6303c0e7136436a2d3cb6043b88edf788c0067cc/src/java.base/share/classes/javax/net/SocketFactory.java#L123). And since [the code](https://github.com/openjdk/jdk/blob/3ebe6c192a5dd5cc46ae2d263713c9ff38cd46bb/src/java.naming/share/classes/com/sun/jndi/ldap/Connection.java#L336) does not check for this behavior, a connection with timeout value through a SocketFactory that does not support unconnected sockets would simply fail with an IOException.
