Redhat Directory Server from redhat-ds to 389-base

Hello Everybody,
I'm trying to install RHEL Directory Server. I'm reading the Directory Server 9.1 Instructions. However It keeps mentioning to install redhat-ds. I find no mentioned of this when I search yum. However, I do find 389-base. I know RHEL's DS is based on 389. Did they change the name of the package in the repo? and if so, what packages should I install? Thank you.
