Most implementation of libpam-krb5 run in two modes. In the first
mode, they try to get credentials for the user being logged in. IN
this mode, no verification happens, and the module is only a
convenience--running kinit to get tickets. In the second mode,
verification is required and the module actually provides
authentication.
Many implementations of libpam-krb5 use the existence of a host key to
determine which mode to run in.
