I am definately no coder. I need to get into scripting a little more. One thing to look into is vmfp (vm fast pass). This will allow quicker authentication in. So you use the normal esxcli commands but then specifiy the targets. If you wanted to write a loop or script that would do on all your hosts that would be ideal. I am no coder so worst case I put it in a text file on my computer and copy paste in and let it do each host by line.
Good luck!
