This is what it looks like when you manually make the change:
admin@PA-VM> configure
admin@PA-VM# set mgt-config users <username> password
Enter password :
Confirm password :
Based on the above, this is what I'm using in the script:
set mgt-config users admin password
nEwPassword111!
nEwPassword111!
Not only does it not work, it somehow sets an unusable password and I have to use a different local superuser account to change the admin password via the GUI.
Any help is greatly appreciated.
