CTT tool issue

[Mohammad Rahil]

Hi Everyone,

I am New to CTT tool, I am running OPC UA server(open62541) and Using CTT tool to connect to it , below are things which I found during my experimentation: 

1. On the project settings tab I am able to do open Browse and also I am able to see the objects created by me. (hence Iam assuming, Iam able to establish connection with the server).

2. In CTT settings tab only I set both message security mode and requested security policy Uri as None.

3. Iam trying to run companion spec (OPC UA FX) , in this iam trying to execute UAFX Asset Connector Id, But iam failing at beforeTest.js itself with errors as Ceritificate does not have a security policy Uri defined.

Below is the error:

Warning:

GetEndpoints.Response.Endpoints[0].UserIdentityTokens[1].Certificate does not have a security policy Uri defined, the secure channel doesn’t either

Error:

Part 4 section 7.36.4 states “the server should specify a security policy for the user token policy if the secure channel has security policy of none”

can someone pls guide me how to resolve this issue, if some changes need to be done on server side then where to do those changes in open62541.

Thanks in advance

Regards,

Rahil

Hi Mohammad

Can you share your code regarding setting up your initial UA_ServerConfig * and all ->accessControl changes if any .

do you call 

UA_ServerConfig_setDefaultWithSecurityPolicies() , if yes with what params.

I am not too deep into it , but if your only calling this , then you most likely miss some or all security / cert features i guess.

hi Robert,

Below is the code for setting up basic server:

UA_Server *server = UA_Server_new();
UA_ServerConfig_setDefault(UA_Server_getConfig(server));

Iam not calling UA_ServerConfig_setDefaultWithSecurityPolicies().

Can you please validate where I am going wrong?

Hi Everyone,

Can someone pls help in configuring the basic server so that CTT Tool can connect to it with all security and cert features.

It would be really helpful, as i am stuck with the basic  connection and not able to move forward.
