created admin user and can login without password

[echoparkbaby]

I created an ladmin user using the python method. (Saving as a pkg file didn't work. It wouldn't save the file in the directory. Nothing ever appeared)
Anyway, I ran the script in 10.13.6 under another admin account. It created the user, but I was allowed to login to the ladmin user without a password. Logged out to login screen, clicked "ladmin" and was signed right in.
