红帽全球峰会第 37 章 Using ID views for Active Directory users
You can use ID views to specify new values for the POSIX attributes of your Active Directory (AD) users in an IdM-AD Trust environment.
By default, IdM applies the Default Trust View to all AD users. You can configure additional ID views on individual IdM clients to further adjust which POSIX attributes specific users receive.
37.1. How the Default Trust View works
The Default Trust View is the default ID view that is always applied to AD users and groups in trust-based setups. It is created automatically when you establish the trust using the ipa-adtrust-install command and cannot be deleted.
The Default Trust View only accepts overrides for AD users and groups, not for IdM users and groups.
Using the Default Trust View, you can define custom POSIX attributes for AD users and groups, thus overriding the values defined in AD.
| Values in AD | Default Trust View | Result | |
|---|---|---|---|
| Login | ad_user | ad_user | ad_user |
| UID | 111 | 222 | 222 |
| GID | 111 | (no value) | 111 |
You can also configure additional ID Views to override the Default Trust View on IdM clients. IdM applies the values from the host-specific ID view on top of the Default Trust View:
- If an attribute is defined in the host-specific ID view, IdM applies the value from this ID view.
- If an attribute is not defined in the host-specific ID view, IdM applies the value from the Default Trust View.
| Values in AD | Default Trust View | Host-specific ID view | Result | |
|---|---|---|---|---|
| Login | ad_user | ad_user | (no value) | ad_user |
| UID | 111 | 222 | 333 | 333 |
| GID | 111 | (no value) | 333 | 333 |
You can only apply host-specific ID views to override the Default Trust View on IdM clients. IdM servers and replicas always apply the values from the Default Trust View.
