红帽全球峰会49.3. Setting the domain resolution order for an ID view on an IdM server
This procedure sets the domain resolution order for an ID view that you can apply to a specific set of IdM servers and clients. This example creates an ID view named ADsubdomain1_first for IdM host client1.idm.example.com, and sets the domain resolution order to search for users and groups in the following order:
-
Active Directory (AD) child domain
subdomain1.ad.example.com -
AD root domain
ad.example.com -
IdM domain
idm.example.com
The domain resolution order set in an ID view overrides the global domain resolution order, but it does not override any domain resolution order set locally in the SSSD configuration.
Prerequisites
- You have configured a trust with an AD environment.
Procedure
Create an ID view with the
--domain-resolution-orderoption set.[user@server ~]$ ipa idview-add ADsubdomain1_first --desc "ID view for resolving AD subdomain1 first on client1.idm.example.com" --domain-resolution-order subdomain1.ad.example.com:ad.example.com:idm.example.com --------------------------------- Added ID View "ADsubdomain1_first" --------------------------------- ID View Name: ADsubdomain1_first Description: ID view for resolving AD subdomain1 first on client1.idm.example.com Domain Resolution Order: subdomain1.ad.example.com:ad.example.com:idm.example.comApply the ID view to IdM hosts.
[user@server ~]$ ipa idview-apply ADsubdomain1_first --hosts client1.idm.example.com ----------------------------------- Applied ID View "ADsubdomain1_first" ----------------------------------- hosts: client1.idm.example.com --------------------------------------------- Number of hosts the ID View was applied to: 1 ---------------------------------------------
Verification
Display the details of the ID view.
[user@server ~]$ ipa idview-show ADsubdomain1_first --show-hosts ID View Name: ADsubdomain1_first Description: ID view for resolving AD subdomain1 first on client1.idm.example.com Hosts the view applies to: client1.idm.example.com Domain resolution order: subdomain1.ad.example.com:ad.example.com:idm.example.comVerify you can retrieve user information for a user from the
subdomain1.ad.example.comdomain using only a short name.[root@client1 ~]# id <user_from_subdomain1> uid=1916901106(user_from_subdomain1) gid=1916900513(domain users) groups=1916900513(domain users)
