Issue

  • Valid SMB clients will be blocked from accessing the CIFS shares, if there are more than 30 invalid attempts with wrong password from the same client IP address regardless of the user logging in.
  • If user 'user1' logs in with invalid password for more than 30 times and then user 'user2' logins with the same client IP address with valid password, then user2 is also blocked.
  • This issue will be seen in FSx systems which has NAT configured or in an equivalent setup where all SMB clients mount with the same IP address.
