The RSA Authentication Manager services fail to restart with a "Permission denied" error on the script file radiuswrapper.sh under /opt/rsa/am/components/ims/unix

The permissions of the file were changed. Comparing with an 8.6 lab, the user and group owner of radiuswrapper.sh should be rsaadmin as shown below. At the customer's side, it is root.

Login to the primary Authentication Manager through SSH, and run the below commands:

sudo su -
*prompted for the rsaadmin password* 
cd /opt/rsa/am/components/ims/unix
cp radiuswrapper.sh radiuswrapper.sh.bk
chown rsaadmin:rsaadmin radiuswrapper.sh
ls -al radiuswrapper.sh (to confirm the change)
exit
/opt/rsa/am/server/rsaserv restart all

The services are restarted normally
