The krb5, des and krb4 sources limit password length to 1023 characters.

The KfM graphical interface limits passwords to whatever the 
operating system's password text field limits are.  The Mac-specific 
code stores password strings in std::strings before passing them to 
the krb5 library, so there's no hard coded length limit.

Hope this helps,
