credentials not working

credentials not working

I have just installed OpManager. It successfully discovered my devices on my LAN and afterwards I selected the devices I wanted to monitor. All of my devices are listed as unknown, so I go and categorize them in their proper category. The last item to input is the password, so I put the username and password in manually and I have also went to admin and placed them in credential settings. It don’t matter which way I try to place the credentials, after I hit test credentials it comes back with, user credentials cannot be used for local connections. Any ideas?
