ILO and OpenLDAP

Hello everyone!

I have to configurate some ILOs  from ILO 2 to ILO 4. I would like to set the authentication by using OpenLDAP.

We succed with an ILO 4 DL380 Gen9 version 2.55 but with an older one (ILO 4 Gen8 v. 2.5), we have some problems.

I have few questions:

Can we use OpenLDAP as authentication method under ILO 4 version 2.55? If not, it is possible for example to upgrade an ILO (from which ILO and version ?)? What is the procedure ?

I know that using an Active Directory LDAP will be more appropriate and easier but I would like to try at first with OpenLDAP.

Thank you a lot :)

Best regards,

R.
