Title: #5766: Sources cleanup - part 3.

pbrezina commented:
"""
After upgrade from json-ed ccache I got:

```
[pbrezina /dev/shm/sssd]$ klist
klist: Internal credentials cache error
```
IMHO it is something to fix if the fix is trivial, but I was able to kinit successfully so it is fine if the fix would be difficult.

I didn't see this debian failure on other pull requests so I would like to wait until we understand what is happening there.
