Cause

Configuration of a plan's source repository authentication with SSH (svn+ssh or cvs+ssh) fails if server sends a MOTD instead of a SSH Password prompt.

Repository authentication via SSH does not work in combination with a MOTD.

Resolution

Disable MOTD messages for the Bamboo user accessing the repository over SSH, by putting LogLevel QUIET into ~/.ssh/config file.
