Description

There is a known issue with JSch running in java 7 and connecting to a server with Kerberos enabled: when trying to connect to that server, it will request the kerberos password to be manually entered even if not used.

The issue is described in the following Ant bug report:
https://issues.apache.org/bugzilla/show_bug.cgi?id=53437 or Mule https://www.mulesoft.org/jira/browse/MULE-6864

Setting "PreferredAuthentications" property to "publickey,password,keyboard-interactive" is the solution preconise by Jsch author: http://sourceforge.net/p/jsch/mailman/message/29359265/
