I'm not aware of any documentation.

Correct--although I heard back from Microsoft that they do not implement
FAST in any version of AD 2003, nor do they use padata type 136 for any
other purpose.  So it's still a mystery to me why you're seeing those
entries when you kinit to your AD server.

We do not currently use any other values, but Heimdal does.  Assuming
people use reasonably descriptive names that don't collide, the
name:value correspondence is a private contract between the caller of
krb5_cc_set_config and krb5_cc_get_config with that name.
