Can a password be set for these sudoers files?
API Gateway 11.X
It should be fine to set the password for the ssgadmin sudoer user as it's expected to be used in an interactive shell session.
However, other user accounts, e.g. ssgconfig, are invoking commands in non-interactive scripts and setting the password for them may break Gateway administration functionality. Support does not recommend changing these settings for other (non ssgadmin) accounts. Certainly, you can experiment at your own risk but if something breaks and you open a ticket, Support will ask you to revert the NOPASSWORD modifications back.
