Description Sumit Bose 2021-08-12 07:21:51 UTC

Description of problem:
If the 'cache_first = True' option is used with the nss responder a lookup with the fully-qualified name of a user or group will fail if the requested object is not already in the cache.

Version-Release number of selected component (if applicable):
It looks like the issue is present at least since RHEL-8.3


Steps to Reproduce:
1. Minimal sssd.conf:
[sssd]
domains = proxy
services = nss
[domain/proxy]
id_provider = proxy
proxy_lib_name = files
auth_provider = none
[nss]
cache_first = True

2. restart SSSD with empty cache
3. call 'getent passwd adm@proxy'

Actual results:
This will return no result

Expected results:
Similar as if 'cache_first = True' is not used in sssd.conf the corresponding entry from /etc/passwd for the user 'adm' should be returned.
