49.5. Setting the domain resolution order in SSSD on an IdM client

This procedure sets the domain resolution order in the SSSD configuration on an IdM client. This example configures IdM host client2.idm.example.com to search for users and groups in the following order:

  1. Active Directory (AD) child domain subdomain1.ad.example.com
  2. AD root domain ad.example.com
  3. IdM domain idm.example.com
注意

The domain resolution order in the local SSSD configuration overrides any global and ID view domain resolution order.

Prerequisites

  • You have configured a trust with an AD environment.

Procedure

  1. Open the /etc/sssd/sssd.conf file in a text editor.

  2. Set the domain_resolution_order option in the [sssd] section of the file. 

    domain_resolution_order = subdomain1.ad.example.com, ad.example.com, idm.example.com
  3. Save and close the file.

  4. Restart the SSSD service to load the new configuration settings. 

    [root@client2 ~]# systemctl restart sssd

Verification

  • Verify you can retrieve user information for a user from the subdomain1.ad.example.com domain using only a short name. 

    [root@client2 ~]# id <user_from_subdomain1>
uid=1916901106(user_from_subdomain1) gid=1916900513(domain users) groups=1916900513(domain users)
