+/*
+   The protocol used between the nslcd client and server is a simple binary
+   protocol. It is request/response based where the client initiates a
+   connection, does a single request and closes the connection again. Any
+   mangled or not understood messages will be silently ignored by the server.
+
+   A request looks like:
+     INT32  NSLCD_VERSION
+     INT32  NSLCD_ACTION_*
+     [request parameters if any]
+   A response looks like:
+     INT32  NSLCD_VERSION
+     INT32  NSLCD_ACTION_* (the original request type)
+     [result(s)]
+     INT32  NSLCD_RESULT_END
+   A single result entry looks like:
+     INT32  NSLCD_RESULT_BEGIN
+     [result value(s)]
+   If a response would return multiple values (e.g. for NSLCD_ACTION_*_ALL
+   functions) each return value will be preceded by a NSLCD_RESULT_BEGIN
+   value. After the last returned result the server sends
+   NSLCD_RESULT_END. If some error occurs (e.g. LDAP server unavailable,
+   error in the request, etc) the server terminates the connection to signal
+   an error condition (breaking the protocol).
+
+   These are the available basic data types:
+     INT32  - 32-bit integer value
+     TYPE   - a typed field that is transferred using sizeof()
+     STRING - a string length (32bit) followed by the string value (not
+              null-terminted) the string itself is assumed to be UTF-8
+     STRINGLIST - a 32-bit number noting the number of strings followed by
+                  the strings one at a time
+
+   Furthermore the ADDRESS compound data type is defined as:
+     INT32  type of address: e.g. AF_INET or AF_INET6
+     INT32  lenght of address
+     RAW    the address itself
+   With the ADDRESSLIST using the same construct as with STRINGLIST.
+
+   The protocol uses network byte order for all types.
