Parse non-standard groups claim as string csv

[blut]

Hello

Our upstream ID provider offers groups as claim in the ID Token formatted as groups: "|group1|group2|".
Since groups are parsed as []interface{}, the claim is never found and the string is neither parsed, nor passed to any client.

I'd like to suggest optionally parsing the groups claim as csv with configurable separator e.g. along the lines of

            vs := claims[groupsKey]
            groupsStr, ok := vs.(string)
            if ok {
                for _, v := range strings.Split(groupsStr, c.groupsSep) {
                    if v == "" {
                        continue
                    }
                    groups = append(groups, v)
                }
            }

Ideally, the solution would allow custom parsing for any separate claimMapping.

Is there a preferred way or suggestion how to achieve the desired result?

We plan to implement a middleware layer that would allow these kinds of transformations: #1635

What I recommend in the meantime is building a custom version of Dex with a modified connector.

Thanks for the info. That's what I'm currently running.
