+If specified, the delegated GSSAPI credential is stored in the
+given path, overwriting any existing credentials.
+Paths can be specified with syntax similar to the AuthorizedKeysFile
+option (i.e., accepting %h and %u tokens).
+When using this option,
+setting 'GssapiCleanupCredentials no' is recommended,
+so logging out of one session
+doesn't remove the credentials in use by another session of
+the same user.
+Currently only implemented for the GSI mechanism.

+authentication.
