Hi all. I have searched for this specific issue on here and got conflicting results, so I thought I'd post. Two things that we are trying to achieve: 1) Change the prestage enrollment local admin password - this one is pretty self explanatory and can easily be done, however will only take effect for newly enrolled computers. Which brings me to 2) Creating a policy that changes the local admin password. I thought I was successful in this and sort of was. Scoping the policy to a couple of test machines resulted in successful change to admin password when authenticating for things such as software installs and preference changes. The new password even works when changing users in terminal (su administrator). However, the password does not work for initial login to the machine. In fact, it breaks the old password as well, so we are left with a machine that the user "administrator" is unable to log in.
I realize this was long winded, so thanks in advance.
