The AD agent requirements only state the server pre-requisites, but does not indicated whether it can be installed into an Active Directory which not not natively in English.
The installation gives a warning indicating the service account should be in the "Pre-Windows 2000 Compatible Access group". The service account is a member of the group, but group name is not in English.

Hello, @Chee-SengL.74757 (Customer)
Hello C Lee,
By default, the Okta AD Agent installer creates a new Okta service account if you don't choose an existing account. The newly created OktaService account inherits the permissions of the Domain Users group. OktaService is also considered to be a member of the Authenticated Users and Everyone special identity groups when the agent is running. By default, the Authenticated Users group is a member of the Pre-Windows 2000 Compatible Access group. Removing the Authenticated Users group from the Pre-Windows 2000 Compatible Access group can cause issues with incremental imports. To resolve issues with incremental imports, Okta recommends making one of the following changes: Add the OktaService account to the Pre-Windows 2000 Compatible Access group. Make sure the OktaService account has Read all permissions for all synchronized AD objects. There is additional information in case you need it here:
