Typing to slow in login screen

[twerf]

Hi all,

We're using Mslogon2 with domain groups to authenticate.
There is some timeout between connect to the server and sending the credentials.
Looks like the timeout is about 20 seconds.

If I am typing slow when I filling in the username and password,
I've got "authentication rejected"
In the server the following log is created:

Code: Select all

  Connection received from <<ip address>>
  Invalid attempt from client <<ip address>>

If I type faster, the connection is working.

Code: Select all

  Connection received from <<ip address>>
  MSLogon authentication accepted from <<ip address>> using <<username>> account (Interactive)

Same issue with Mslogon(1)
Local password does not have this issue.
I've tried to change the IdleInputTimeout and IdleTimeout.
Both does not fix this.

Is this an known issue?
Is there another timeout?
What can we do about it? (Besides typing faster )
Thanks!
