Subject: [PATCH 69/93] NEGCACHE: Add root's uid/gid to ncache

As "root" is not handled by SSSD, let's add its uid and gid to the
|
||
|
|
negative cache as well. The reason it's added without specifying a
|
||
|
|
domain is to follow how the negative cache is used by cache req's code
|
||
|
|
when searching something by id.
|
||
|
|
|
||
|
|
As the negative cache check for uid/gid, in the cache req code, is done
|
||
|
|
after resolving the name, we can save one LDAP call to the data
|
||
|
|
provider.
