It doesn't work on iOS as well.
Nextcloud auth is not implemented yet.
Can you ping me on https://open.rocket.chat?
I'm @diego.mello.
Let's implement this asap.
Thanks.

It could be very cool to have this fonctionality !

I had to go forward and Nextcloud can be configured as Custom OAuth, which is supported by the App.

1. Firstly create a Custom OAuth in Rocket Chat server settings, copy the Callback URL
2. Create a new OAuth Client in Nextcloid Security settings, use the Callback URL.
3. Copy Id and Secret from Nextcloud
4. In Rocket Chat Server configure the Custom OAuth provider as follows:

• Enable: checked
• URL: [your nexcloud base url]
• Token Path: /apps/oauth2/api/v1/token
• Token Sent Via: Header
• Identity Token Sent Via: Same as "Token Sent Via"
• Identity Path: /ocs/v2.php/cloud/user?format=json
• Authorize Path: /apps/oauth2/authorize
• Scope: openid
• Param Name for access token: access_token
• Id:  [paste from NextCloud OAuth client configuration]
• Secret: [paste from NextCloud OAuth client configuration]
• Login Style: [make your choice]
• Button Text: [your choice]
• Button Text Color: [your choice]
• Button Color: [your choice]
• Username field: ocs.data.id
• Email field: ocs.data.email
• Name field: ocs.data.display-name
• Avatar field: [leave empty]
• Roles/Groups field name: ocs.data.groups
• Merge Roles from SSO: uncheck
• Merge users: check
• Show Button on Login Page: check

Thanks a lot i use your solution @loxK !

I try to get the merge roles fonctionality work but it don't you have any idea how to do it ?

[yodatak]

I can't find the ocs.data.groups

[loxK]

I don't use that feature. I tried and it made my account to loose the admin role in Rocket Chat. I didn't dig further.

Same for me 👍

Nice workaround @loxK! I'll use this to develop the right way and do this working, probably at the next week!
Thanks! 😃

Hello @djorkaeffalexandre, is there something new ?

[czadikem]

Yeah has this been implemented yet? Or is it in the works?

[linusgke]

Any updates on this? @loxK's workaround didn't work for me!

All oauth config fields for Nextcloud filled appropiately in RocketChat server settings under https://.../admin/settings/OAuth

Rocket.Chat Version: 6.6.0
     NodeJS Version: 14.21.3 - x64
    MongoDB Version: 5.0.24

with Android App Version 4.46.1.57002

No OAuth Button for login in the mobile app only and the following log message when trying to connect:

{"level":40,"time":"...","pid":9,"hostname":"...","name":"DeprecationWarning","section":"API","msg":"The parameter \"query\" in the endpoint \"/api/v1/settings.public\" is deprecated and will be removed on version 7.0.0"}

Login from Web Browser works fine.
