MacOS Sierra 10.12.6 problems.

Hi All,
out of the blue some of our users started having issues after there device would go to sleep they would not be able to log back in, the local admin account works but not the mobile accounts. I have looked every where with no sure answer where to go next. User are enrolled in Jamf and bound to AD using Jamf have no problems logging in and out of the device or even doing a switch user and adding a new AD account to the device by just login in. I have switch the preferred server to a local domain controller in the office and the users are able to login and out fine. As soon as the device goes to sleep Wi-Fi connected or in the Landing zone dock users and not able to log in, now they can lock the screen saver with out a problem but not place the laptop in sleep mode. I'm at the point now where I would like to disable the network connection when the users log out using a bash script and have another script run to turn them on at login. is there a way for me to check what network connects are on the device and then run ifconfig en0,en1,en2 etc.. to turn them off? at this point I run the ifconfig en5 down and if the en5 does not exist I get a email from Jamf telling me there is a error in the script. All I can hope at this point is to disable the network connection if the device goes to sleep and force the ma to uses the local cashed account.
