an implementation of the ldap wire protocol
val encode_resultcode : Ldap_types.ldap_resultcode -> intreturn the int asociated with the specified result code
val decode_resultcode : int -> Ldap_types.ldap_resultcodereturn the result code for the specified int, error codes which do not map to a code defined within the standard (or any of our own internal ones) will be represented as (`UNKNOWN_ERROR of int), where int is the unknown error code.
val encode_ldapmessage : Ldap_types.ldap_message -> stringencode a value of type ldap_message using lber and return a string which is ready to be put on the wire
val decode_ldapmessage : Lber.readbyte -> Ldap_types.ldap_messagedecode an ldap_message from the wire, and build/return a structure of type ldap_message
