Description Niranjan Mallapadi Raghavender 2019-12-04 04:11:48 UTC
Description of problem:
background refresh task does not refresh updated netgroup entries. When refresh_expired_interval is specified in sssd.conf and netgroup entries are updated in ldap server. the refresh task doesn't update fetch the latest netgroup entries. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install sssd-2.2.0-19.el8.x86_64 

2. cat /etc/sssd/sssd.conf
config_file_version = 2
services = nss, pam
domains = example1

ldap_search_base = dc=example,dc=test
id_provider = ldap
auth_provider = ldap
ldap_user_home_directory = /home/%u
ldap_uri = ldaps://idm-qe-01.lab.eng.rdu2.redhat.com
ldap_tls_cacert = /etc/openldap/cacerts/cacert.pem
use_fully_qualified_names = True
debug_level = 9
debug_level = 0xfff0

2. Setup ldap server with netgroup entries. as shown below:

dn: cn=netgroup_1137010,ou=Netgroups,dc=example,dc=test
objectClass: top
objectClass: nisNetgroup
cn: netgroup_1137010
nisNetgroupTriple: (host1,user1,example1.com)

3. Run getent netgroup netgroup_1137010

[root@idm-qe-01 db]# getent netgroup netgroup_1137010
netgroup_1137010      (host1,user1,example1.com)

4. Modify netgroup entry 
dn: cn=netgroup_1137010,ou=Netgroups,dc=example,dc=test
changetype: modify
replace: nisNetgroupTriple
nisNetgroupTriple: (host1137011,user1137011,example.com)

[root@idm-qe-01 db]# ldapmodify -x  -D "cn=Directory Manager" -w Secret123 -h localhost -f /tmp/net2.ldif
modifying entry "cn=netgroup_1137010,ou=Netgroups,dc=example,dc=test"

5. After 22 seconds the netgroup entry should be updated in sssd cache.

6. Run ldbsearch to check the cache. 

# record 7
dn: name=netgroup_1137010,cn=Netgroups,cn=example1,cn=sysdb
createTimestamp: 1575432366
name: netgroup_1137010
objectClass: netgroup
originalDN: cn=netgroup_1137010,ou=Netgroups,dc=example,dc=test
originalModifyTimestamp: 20191204040527Z
netgroupTriple: (host1,user1,example1.com)
lastUpdate: 1575432366
dataExpireTimestamp: 1575432396
distinguishedName: name=netgroup_1137010,cn=Netgroups,cn=example1,cn=sysdb

Actual results:

Netgroup entries are not fetch the updated netgroup entries from server and update the cache. 

Expected results:

netgroup entries should fetch updated netgroup entries from server and update the cache.
