I've just upgrade to firmware 8.3R7.1 and now i have this error when i test user authentication :
=== Test User Authentication ===
User authentication for user rrr4444 ... [FAILED]
Returned error code : STATUS_LOGON_FAILURE
The attempted logon is invalid. This is either due to a bad username or authentication information.
All is green when i make the basic verification on my AD connection.
User authentication doesn't work but user password change works fine!!!
I've restart AD services and reset join severail times.
Please help! Thanks
