Help to increment freeradius wait timeout in

[Kamal Majaiti]

Problem:
Good morning, I am trying to perform a 2FA after a correct validation with
MSCHAP against active directory, the postauth executes a script that sends
an email with a link to confirm and authorize access, when the link is
clicked, access is authorized based on data meanwhile the script with a
while waits for the access to be confirmed but freeradius doesn't wait and
gives me the following error:

(0)       Executing: /bin/bash /etc/freeradius/3.0/otp/enviar2FA.sh
