functions.sh shell error: integer expression expected

[edthrn]

When trying to generate a new client, I get the following error (using v1.13.0):

./functions.sh: line 14: [: no: integer expression expected

Replacing this line by the following line solves the problem:

# note the double brackets
if [[ "$PASSWORD_PROTECTED" -eq 1 ]]; then

I do not get any error, but I'm also not able to generate password protected clients with ./genclient.sh np profile_name.
