@rpignolet the PR adds the powertool repo for openldap-servers on Alma, the same as it is done for Rocky8.

tdp-collection-prerequisites/README.md

Lines 3 to 8 in 0b48bd5

	## Supported distribution
	- Rocky 8.6+
	- Alma[^alma] 8
	[^alma]: Alma does not provide `openldap-servers` package so it is not supported for host in `[kdc]` Ansible group.

I have not of the background of this, do you think this is outdated ?

[rpignolet]

Alma have openldap-servers now so yes it is outdated. When I checked for Rocky, Alma didn't have the package in her repositories.
