Description of problem:
When performing an offline login with no existing credential cache (first login after boot or after a kdestroy), the SSSD does not generate a pre-expired placeholder cache.

Version-Release number of selected component (if applicable):
sssd-krb5-1.11.1-2.fc20.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. kdestroy
2. sudo killall -USR1 sssd (to force offline auth)
3. su - <username>
4. klist

Actual results:
The login succeeds with cached credentials, but the output of klist shows no credential cache.

Expected results:
The login succeeds with cached credentials and the output of klist shows a credential cache that expired long ago (actually the dawn of the epoch).

Additional info:
The primary reason for the placeholder cache is so that applications like krb5-auth-dialog can monitor the cache and notify the user when it is updated or expired.

Also, this appears to be related to the KEYRING:persistent cache only. When I switched to 'krb5_ccname_template = FILE:/tmp/krb5cc_%U_XXXXXX" and followed the above steps, the placeholder cache was properly created.
