I have just created a new DW 9.15.3 solution.
1. Created a user
2. Send GET Requests to /dwapi/users/authenticate?userName=<the users username>&password=<the users password>&expirationInSeconds=1800
3. I get a token in return
4. When I want to get the token via Dynamicweb.Security.Tokens.TokenService.GetToken(token) it returns null
5. Found out that the token is not registeret in AccessUserTokens table
6. If I register my token manually in the AccessUserTokens table then Dynamicweb.Security.Tokens.TokenService.GetToken(token) it returns my Token object.
Do I have to enable something for this to work?
