Issues with dell iDrac and vault public key

Has anyone been able to get vault key working with Dell iDrac? I tried to add the key like I did with my personal pub key, but the system gives me a “ERROR: Key is too long.” msg when I do the following: idracadm7 -r <HOST> -u <user> -p <passsword> sshpkauth -i 2 -k 3 -f <vault-pub-key.file>

When using the gui it takes the key, but the key does not work, so not sure what is up there.

Has anyone else had this issue or managed to get idrac working with vault?

Also, in talks with dell support atm, and can’t find what command it is that vault is running in the gui to create the public key; does anyone know the command so that I can forward it to support?
