# VERIFICATION FOR XENIAL

Following the instructions in the description, 'user1' is present in the db:

root@vtapia-xenial:/var/log/sssd# sudo sss_cache -E; getent passwd 'user1'
root@vtapia-xenial:/var/log/sssd# sudo ldbsearch -H /var/lib/sss/db/cache_openstacklocal.ldb -b name=user1,cn=users,cn=openstacklocal,cn=sysdb | grep entries
asq: Unable to register control with rootdse!
# 1 entries

And after a manipulated user request, the entry in the db persists:
root@vtapia-xenial:/var/log/sssd# sudo sss_cache -E; getent passwd 'user1
> '
root@vtapia-xenial:/var/log/sssd# sudo ldbsearch -H /var/lib/sss/db/cache_openstacklocal.ldb -b name=user1,cn=users,cn=openstacklocal,cn=sysdb | grep entries
asq: Unable to register control with rootdse!
# 1 entries

The log shows how the username has been sanitized:
