As also discussed with Alexander on IRC, we do not want to have private ccache
for ipa-adtrust-install as we deliberately re-kinit admin user to add new
MS-PAC information to the ticket so that subsequent trust commands work. In
other install scripts, we want to have private ccache so that we don't mess
with user's default ccache.

This entire problem should go away when krb5 is fixed, see

Thus, your current fix for private ccaches is correct.
