Check if /usr/local/lib/sasl2/liblogin.so exists - if not you have to
recompile sasl with LOGIN mech support.
Check in your .mc file if you define confAUTH_OPTIONS macro. If you do
make sure 'p' parameter is not on the list or LOGIN would be available
only after TLS encryption which is not a case for you as your working
configuration offers LOGIN during telnet session (it's actually a bad
idea to do authentication clear text).
