I seem to be seeing some strange behaviour on host profiles and autodeploy in 5.0. I have now edited the profile, gone to security and set an administrator password numerous times, applied the profile to the hosts but it keeps going back to leave password unchanged. I have a 5.1 lab and when I change the password it seems to work.. I haven't applied any updates just yet, perhaps this is a bug?
Reviewing your posts on the forum... look like we are running into the same problems with auto-deploy.
I had it running in a lab last year and it was working great now trying to implement it in prod and I do see a lot of inconsistency. Working with vmware we blessed the auto-deploy side of things but we seem to problems with the profiles.
