Hello,

Getting Bad_IdentityTokenRejected StatusCode means that the Server has rejected the credentials that were used to attempt to activate a Session. This StatusCode can mean that either the given credentials were incorrect or the Server does not support the selected UserTokeType at all.

Is the Server or the Client developed with Prosys OPC UA SDK for Java?

Hello,

What type of IdentityToken are you trying to use? Anonymous, UsernameAndPassword, UserCertificate or something else? If you’re getting Bad_IdentityTokenRejected StatusCode and think the IdentityToken you’re using is correct, there might be something wrong with the Server’s user authentication implementation. This is done by a class that implements the UserValidator interface.

Hello,

That would suggest that either the Server does not support the given combination of username and password or it does not support using UsernameAndPassword IdentityTokens at all.

Please take a look at the MyUserValidator class of SampleConsoleServer sample project for an example of how to check usernames and passwords on the Server side.

Also, make sure that the Server has been configured to support UsernameAndPassword UserTokenPolicy. Take a look at the initialize method of SampleConsoleServer class for an example of how to configure supported UserTokenPolicies.
