Hi @jimscarver,

Thanks for your feedback,

This documentation might be of assistance for your setup?


Thanks. I followed those instructions but did not find any instruction on the values to use for the username key, name key, email key, or user id key.

In https://kanboard.net/plugin/oauth2 the examples have different values for different systems but does not say what values to use for mattermost.

Example for Github OAuth2:
Username Key: login
Name Key: name
Email Key: email
User ID Key: id

Example for Salesforce:
Username Key: nickname
Name Key: name
Email Key: email
User ID Key: user_id

I am currently using the values

Scopes: login
Username Key: user_id
Name Key: name
Email Key: email
User ID Key: user_id

And getting an error in the login screen returned.
“The OAuth2 state parameter is invalid”

I assume I guessed wrong one or more of the parameters.


Thanks @jimscarver,

I’ll ask the team to weigh in to see if they can help troubleshoot your issue further…


We seem to be authenticating on the mattermost side with the values we chose but fail on the kanboard side.
The state error was my mistake, a red herring.


I still have not found the correct parameter mapping to configure for mattermost. Can anyone help?
