Password script + Touch ID

Question

Hello,

for our password policy we are using a script we have found here on Jamfnation. This runs perfectly on MacBooks (Mid 2015) but with the new MacBooks 2016 and Touch ID not. After a several of logins (4 or 5 times) i can’t login anymore. I got a hint that the password is wrong (shaking password field) and then i got a black screen and i can only see the cursor. Only with a hard shutdown i can fix the problem.

If Touch ID disabled, then i haven’t the problems. Does somebody has any idea?

## Pupose:  Create a pwpolicy XML file based upon variables and options included below.
##          Policy is applied and then file gets deleted. Use "sudo pwpolicy -u <user> -getaccountpolicies"
##          to see it, and "sudo pwpolicy -u <user> -clearaccountpolicies" to clear it.
##
## Usage:   Edit variables in Variable flowerbox below.
##          Then run as a policy from Casper, or standalone as root.
##
## Tested on: OS X 10.10 and 10.11

MAX_FAILED=10Sierra is sending more than one authentications attempts. There are reports that it will be fixed in 12.3. You can search here for AD, iCloud  and Sierra to get more info..C
