[SSSD] [PATCH] mmap_cache: Store corrupted mmap cache before reset

[Michal Židek]

Hello,

I think it could be useful to store the corrupted memory cache
before reset. We have very little info about what was really
wrong in the cache when it was in inconsistent state. This way we
could ask users to send us copy of the corrupted cache if they
hit this issue. It could provide some more answers.

Patch is attached. It stores the corrupted cache in
/var/lib/sss/mc/<cache_name>_corrupted.

Thanks
Michal
