[QA] desktop client does not start oidc flow

[jnweiger]

Seen with openidconnect-2.2.0-rc.3 on server 10.11.0-rc.2 using desktop client 2.11.1

• Setup server with kopao idp
• login admin via web ui and normal login button. Works. OK.
• login aaron_beer via web ui and kopano button. Works. OK.
• start desktop client and add the server url.
• The client prompts for username and password. BAD.
• kopano user aaron_beer can log in with his password. Strange.

Expected behaviour:

• after entering the server url, the client opens a browser window to the kopano IDP
• login credentials are not entered into the client.

Regression:

• openidconnect-2.1.0 on server 10.11.0-rc.2 using desktop client 2.11.1 starts the oidc flow correctly.

Test systems:

• https://oc10110rc2-oidc-210-20220916.jw-qa.owncloud.works
• https://oc10110rc2-oidc-220rc3-20220916.jw-qa.owncloud.works

Not working because we send

www-authenticate: Bearer/PoP realm="ownCloud"

which is not understood by the client ....

Confirmed fixed:

• Client 2.11.1, Server 10.11 with openidconnect 2.2.0-rc.6 and keycloak.
