第 9 章 Tuning SSSD performance for large IdM-AD trust deployments
Retrieving user and group information is a very data-intensive operation for the System Security Services Daemon (SSSD), especially in an IdM deployment with a trust to a large Active Directory (AD) domain. You can improve this performance by adjusting which information SSSD retrieves from identity providers and for how long.
Apply tuning options to the configuration of the SSSD service in an IdM server to improve its response time when retrieving information from a large AD environment.
Prerequisites
-
You need
rootpermissions to edit the/etc/sssd/sssd.confconfiguration file.
Procedure
-
Open the
/etc/sssd/sssd.confconfiguration file in a text editor. Add the following options to the
[domain]section for your Identity Management (IdM) domain:[domain/<idm_domain_name>] ignore_group_members = true subdomain_inherit = ignore_group_members ...注意Settings listed in the
subdomain_inheritoptions apply to both the main (IdM) domain as well as the trusted AD domain(s).-
Save and close the
/etc/sssd/sssd.conffile on the server. Restart the SSSD service to load the configuration changes.
[root@client ~]# systemctl restart sssd
