DRAC Authentication

I definitely understand the reasons for wanting consistent 
authentication on the DRACs, but I would prefer your script that syncs 
passwords as opposed to having the DRACs rely on an external service.

How would you fix a server if the LDAP directory was unavailable, like 
say, the local network was down? What if you're trying to fix a broken 
LDAP server using the DRAC, but the DRAC relies on the LDAP server?

DRAC is the life raft, it should have no dependencies besides power, 
network, and cooling.

I understand that these concerns can be mitigated with redundant LDAP 
servers, but you can run into weird situations where you can't do 
maintenance on servers while the LDAP server is under maintenance. How 
many shops have a defined maintenance window when all/most maintenance 
must occur?

This reminds me of the cartoons where the character is stranded on the 
desert island with canned food, but has no can opener.

All that said, I'm still interested in how to customize the DRAC configs.
