The "Require SSL/TLS" option doesn't have positive effects. That is to
say, turning it on will not enable an account to connect that will not
connect when the option is off. All this option does is generate a
connection error if TLS is not able to be negotiated.
Similarly (but oppositely), the "Allow plaintext authentication over
unencrypted streams" should not actually *break* a connection where it
was working previously; it will only enable a connection to try unsecure
authentication methods (see answer to your question below).

It means you're sending your password in plaintext (or a
plaintext-equivalent) over an unsecure line. That is to say, anyone who
can see your network data now knows your username and password.

There should be no substantive difference in the functioning of these
two versions when it comes to the application of the aforementioned

What server is this? The Help->Debug Window output from both Pidgin
2.6.1 and Pidgin 2.7.3 connecting would be highly useful, because Pidgin
just shouldn't be operating the way you've described.
