Introduction

   The following is the description of a TELNET option designed to
   facilitate double login avoidance.  It is intended primarily for TAC
   connections to target hosts on behalf of TAC users, but it can be
   used between any two consenting hosts.  For example, all hosts at one
   site (e.g., BBN) can use this option to avoid double login when
   TELNETing to one another.
