A credential cache (or “ccache”) holds Kerberos credentials while they remain valid and, generally, while the user’s session lasts, so that authenticating to a service multiple times (e.g., connecting to a web or mail server more than once) doesn’t require contacting the KDC every time.
A credential cache usually contains one initial ticket which is obtained using a password or another form of identity verification.
I am writing a p Gina plugin to get AFS Tokens and a Kerberos TGT from our kdcs at login, while writing I noticed a 'feature' of kinit being that it wont let you provide any input unless its from the keyboard, there went my idea of just redirecting the standard input...

Native Method Accessor Impl.invoke0(Native Method) at sun.reflect.However, when you change your Kerberos password, you will need to recreate all your keytabs.Keytab files are commonly used to allow scripts to automatically authenticate using Kerberos, without requiring human interaction or access to password stored in a plain-text file.I also can query the Open LDAP server if I am prompted to input the user/password.
