+\H{errors-toomanyauth} \q{Server sent disconnect message type 2
+(SSH_DISCONNECT_PROTOCOL_ERROR): "Too many authentication failures for root"}
+
+This message is produced by an OpenSSH (or Sun SSH) server if it
+receives more failed authentication attempts than it is willing to
+tolerate.  This can easily happen if you are using Pageant and have a
+large number of keys loaded into it.  This can be worked around on the
+server by disabling public-key authentication or (for Sun SSH only) by
+increasing \c{MaxAuthTries} in \c{sshd_config}.  Neither of these is a
+really satisfactory solution, and we hope to provide a better one in a
+future version of PuTTY.
