Javadoc
Indicates whether to operate in synchronous mode, in which at most one
operation may be in progress at any time on a given connection, which may
allow it to operate more efficiently and without requiring a separate
reader thread per connection. The LDAP SDK will not absolutely enforce
this restriction, but when operating in this mode correct behavior
cannot be guaranteed when multiple attempts are made to use a connection
for multiple concurrent operations.
Note that if synchronous mode is to be used, then this connection option
must be set on the connection before any attempt is made to establish the
connection. Once the connection has been established, then it will
continue to operate in synchronous or asynchronous mode based on the
options in place at the time it was connected.
