As a security measure, you can configure Hue to lock an account after a set number of
unsuccessful or invalid login attempts by specifying the number of attempts in the
login_failure_limit parameter and setting the login_lock_out_at_failure parameter to true in
the Hue Advanced Configuration Snippet in Cloudera Manager.
-
Log in to Cloudera Manager as an Administrator.
-
Go to and add the following lines in the Hue Service
Advanced Configuration Snippet (Safety Valve) for
hue_safety_valve.ini field:
[desktop]
[[auth]]
login_failure_limit=[***NUMBER-OF-ATTEMPTS-BEFORE-ACCOUNT-LOCKOUT***]
login_lock_out_at_failure=true
Replace [***NUMBER-OF-ATTEMPTS-BEFORE-ACCOUNT-LOCKOUT***]
with the number of unsuccesful login attempts after which you want to lock an
account. For example, if you set login_failure_limit to
3, then the user will be locked out on the third invalid
attempt.
-
Click Save Changes.
-
Restart the Hue service to apply stale configurations.
You can use the Rolling Restart option to minimize
downtime.
A user's account will be locked out after crossing the set
number of invalid login attempts and the following message is displayed
"Account locked: too many login attempts. Contact an admin to unlock
your account."
