SOLUTION: Kerberos KDS won’t start after switching to OD master

OK. I’m sure this has been posted somewhere before but I’m too lazy to dig through the search results on the forum looking for a match, so I thought I’d post it anyway since it comes in really handy and seems to happen a lot. This solution is courtesy of Steve at macspecialist.

The problem happens during initial setup. So these steps will delete all
user passwords from the password server. If there are existing users
that have passwords stored in the password server, you will have to
reset their passwords after doing these steps.

You need to make sure the server can do forward and reverse lookups of
it’s name and ip.

Set the server back to standalone.

run NeST -NOpasswordserver (as root)

then run NeST -hostpasswordserver adminusername adminpassword (the admin user that lives in the local nidb)

reboot the server.
