How can I use custom authentication while still getting crowd groups in Fisheye
Asked by Eli Kim:

We have developed our own custom authenticator. The back-end is still Crowd but we wanted things different from username/password. We have it working correctly however by doing this we are unable to bring in CROWD groups. In the AuthToken I do not see anything relating a user to groups. Is there any way to get this relationship in? Fisheye only allows for one authentication method but the groups are linked to that authentication only? How would a custom authenticator manage groups?

It looks pretty straightforward.

Are we missing anything? Are we doing something different than what is needed?

author: Alin Tomoiaga
body: Hi, we are facing a related issue that you seem to have already solved. Could you please advise?

```
We wrote a custom authenticator, Fisheye is configured to use it, I can test it using the interface and the *.log file also displays the expected messages. The user exists and is also configured to use custom authentication.The custom authenticator overwrites the checkRequest method and it returns, as needed, a non null token. But, although the custom authenticator is called and it returns a token, Fisheye still displays the login screen.Please advise on what else prevents the user from being logged in.
```

comments: author: Eli Kim
body: I extended the AbstractFishEyeAuthenticator, re-implemented checkRequest and hasPermissionToAccess. In addition recreateAuth and checkRequest, both needed to return my own implementation of AuthToken.

The shortcoming with custom authentication is if you use Fisheye with Crowd to manage the groups. Fisheye currently has no way to have a custom authentication and manage groups from within Crowd like JIRA and Confluence offers.

HUGE shortcoming for us... made the custom authenticator useless for us until Atlassian decides to either open it up in the plugin code so that we can do it ourselves or they do it so that groups and authentications aren't mixed together.
