Public bug reported:
I configured sssd on an Ubuntu 16.04 LTS system, and it worked just
fine. In fact, using the same sssd.conf file (which is managed by
puppet) on un-upgraded system continues to work fine.
However, after upgrading to 18.04.1 LTS, I find that the system is
continuously forgetting who I am. After a few commands, or a few
minutes (I'm not sure exactly how many, but around 3-5 minutes) if I try
to run sudo or whoami, it says that I am an unknown user. for example,
```
whoami
whoami: cannot find name for user ID 2000: Unknown error 1432158300
```
if I run the id command on my username, it returns the correct results,
and whoami/sudo/other restricted commands will work again for a short
time before forgetting who I am again.
In the sssd_nss.log file, I see the lookup against the @local domain,
but I do not see a related lookup in the ldap domain either in that log
file or in the log file specific to the ldap domain.
