Ok I figured it out. I'm not sure if I just missed this somewhere in the documentation but the admin login is "administrator" not "admin".
I deployed the NetWorker OVF as a vm in our vmware environment, then went into the /avigui and installed and configured it. Now I can't seem to log in to the Web UI / NWUI with either the root or admin credentials which are the only credentials, as far as I can tell, in the system. Do I have to setup anything else, like the authentication service or the NMC server? I also can't SSH into the Networker server but it seems like it's not set up for that. Any idea what I might be doing wrong?
