Been bashing my head against a wall trying to add user to my new opnsene machine this evening.
Adding a user isn't an issue but unfortunately i can never log in though the web interface using this newly created user.
Do i have to do anything special to make log in through the web interface possible?
I can't see anything in the documents https://docs.opnsense.org/manual/how-tos/user-local.html
Perhaps i need to add the user to some sort of group giving it privileges?
Yes, you will need to add the user to a group with the required privileges, or set the privileges manually under Effective Privileges in the user config
That's good to know.
I guess i expected that to happen automatically as the web interface is the primary place to log in and what's the use of adding a user if you cant use it.
Can confirm that the privileges was the issue.
Quick guide for anyone in need
System>Access>Groups
Add a user group like user. Append webgui permissions of your choice (i did dashboard permissions only) save go back to System>Users and make your new user a member of the group user.
You can now log in using the webgui with your newly created user.
