How to Create User.json File or use "SetUsers"-Command
Hello,
im having issues with creating users for my OPCUA Server.
I have created Json file like this:
{"username":"User1","password":"Password123", "role":"Administrator"}
as well as
[{"username":"User1","password":"Password123", "role":"ConfigureAdmin"}]
and I linked this in my OPCUA Server under Users File.
But when I try to connect I get this error:
I was not able to find an example of how to create and use users in your examples. Could you please help me out?
Start from the command line with the -v option. Then you can see how it loads users.json
Perhaps directory separator \ should be /
Look line: Trying to load default users from file: c:/temp/users.json

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

Hello,
thank you for your quick reply.
However I have now run into new issue.
While trying to fix this I updated the OPCUA Nodes Palette and now my .XML File will not work anymore.
CSBME.zip
It worked fine before but now it never builds the namespace like it should.
On my other PC with old Version it works with same file and looks like this:
But on new one it it never shows the "CTX" Object and Variables under it.
I tried all kinds of different variations of how to load the .XML file:
C:/User/... C:/Benutzer/... C:\User... C:\Benutzer Only CSBME.XML, with the file being inside the Node-Red-Contrib and ...Contrib/opcua folders.
When using User as the folder Node-Red gave me an error "Directoy not found" everytime. With german "Benutzer" as user it doesn't throw an error but still wont create the Server like it should.
Check this, it is not anymore one file, it is folder:
It was very short time loading one file and I updated it to load all files from the folder.
Thank you!!! This fixed the Nodeset.
But users is not working yet sadly.
I see only this when I enter OPCUsers.json and I can't open Node-Red after
Whats interesting is this. When I just enter OPCUsers.json and put it in the correct folder Node-Red still tells me that it cant be found:
Strange. Because it works on the Custom nodeset with \.
On the OPCUsers.json it doesnt work with /. See here:
But now it doesn't throw me an error with: "C:/Users/marvin/.node-red/node_modules/node-red-contrib-opcua/opcua/OPCUsers.json"
But when i try to use this in UAExpert I cant connect:
It loads the Users but still not working in UaExpert
When I connect as Anonymous it works and says "Reason: True" cmd
When I try user and PW it just says "Reason False" in cmd
UserIdentity [{"type":0}] is anonymous?
If I change user then I see this on UaExpert:
Sign means it will use user & password given below "Use credentials"
As verbose is on it will show on console this information: 15 Nov 16:04:27 - [info] [OpcUa-Client:9be75df2.167] Create session ... Create session with userIdentity: [{"userName":"1","password":"2","type":1},"visitor","qwerty"] 15 Nov 16:04:27 - [info] [OpcUa-Client:9be75df2.167] Create session with userIdentity: [{"userName":"1","password":"2","type":1},"visitor","qwerty"]
Yes I do. type:0 is for anonymous I think yes.
After I enabled all settings here (now I disabled Anonymous to test) it works. Even tho I choose none/none in UaExpert.
I was able to connect with UaExpert using User and PW. Node, like write multiple can also connect using the User and PW.
But only when setting SecurityPolicy and SecurityMode to "None". If I set them to Basic 256 and Sign I get this error:
Works when using None + None:
Depends on what you have active on server node allowed settings.
And if you have multiple client nodes remember to change parameters in each of them.
