/**
* This class provides an API that is used to represent an LDAP bind request.
* It should be extended by subclasses that provide the logic for processing
* specific types of bind operations (e.g., simple binds, and the various SASL
* mechanisms).
*
* It is strongly recommended that all bind request types which implement the
* rebind capability be made immutable. If this is not done, then changes made
* to a bind request object may alter the authentication/authorization identity
* and/or credentials associated with that request so that a rebind request
* created from it will not match the original request used to authenticate on a
* connection. Note, however, that it is not threadsafe to use the same
* {@code BindRequest} object to attempt to bind concurrently over multiple
* connections.
*
* Note that even though this class is marked with the @Extensible annotation
* type, it should not be directly subclassed by third-party code. Only the
* {@link SASLBindRequest} subclass is actually intended to be extended by
* third-party code.
