ISE 2.2 Network Device Admin Failed Attempt Retries

[M.G.]

I need to set the maximum number of failed login attempts for TACACS+ and RADIUS authentications and return a message to the user ("your account is now disabled...").

I have  ticked  Lock/Suspend Account with Incorrect Login Attempts, and set the number to 3.

to test, I am using putty to login to a device.

Although failed attempts are logged in TACACS live logs, neither Disable account nor Suspend account for X minutes comes into effect after exceeding the number of failed attempts.

The ISE version is 2.2.0.470 patch 12.

How can I fix the issue?

how do you login to the device ? is it ssh ( via putty) . enable ssh on device, open 3 simultaneous sessions and give it a try

Thanks,

Nidhi

Thank you Nidhi,

Update from me,

The problem was with the way I performed the test and checked the results.

the correct way of checking it:

basically before the 3rd failed login attempt the failure message in Operations > TACACS> Live Logs looks like this:

Message Text Failed-Attempt: Authentication failed
Failure Reason 24408 User authentication against Active Directory failed since user has entered the wrong password

After the 3rd failed login attempt the failure message is 

Message Text Failed-Attempt: Authentication failed
Failure Reason 24415 User authentication against Active Directory failed since user's account is locked out

This will be the case even with correct credentials in 4th attempt onward , unless I unlock the account (in my case in AD).
