Inquiry about FreeIPA installation #6

Open MaitaYuki opened 1 year ago

MaitaYuki commented 1 year ago

@nateGeorge , thanks for the post. In the mid of installation of step 4 of freeIPA, I will be prompted to enter the Kerberos realm, the hostnames of Kerberos servers and the hostname of the administrative server for the Kerberos realm. E.g. Kerberos realm: COMPUTINGFORGEEKS.COM Kerberos Server hostname: ipa.computingforgeeks.com Administrative server hostname: ipa.computingforgeeks.com

I have a question. Do I need to change these inputs according to my network name? For example, if I work for a.ca, I should change to Kerberos realm: a.ca Kerberos server hostname: ipa.a.ca Administrative server host name：ipa.a.ca

Is my understanding correct?

Another question: In step 1 , host name is changed to ipa.example.com. If my company is a.ca, should I change it to ipa.a.ca or it does not matter?

Thanks!!!

I think your understanding is correct but it's been a few years since I've worked with this. You will probably find better support on another forum related to FreeIPA. Possibly they have a mailing list, reddit, or you can try stack overflow. You can update us with your findings here as well if you wish.

I have a doubt, mostly due to my ignorance. But if I have an authentication system with freeIPA for SLURM is it mandatory to milk it?
