Bug Description

We've configured OIDC to a Microsoft ADFS IdP (not Entra, real On-Premise ADFS) and connection of users is ok but they get generated (?) username and no personnal information populated :

See screenshot section

How to Reproduce

1/ Generate new Applications Group on ADFS Server console with :

• Application Server

• URI redirection as https:///api/oidc/callback
• ID client
• ID secret

• Web API

2/ in Rustdesk server :
Settings --> OIDC
Add "New Auth Provider" with "Auth Type" as "Custom

Configure "Name", "Client id" and "Client Secret" from ADFS.
Specify "https:///adfs" as Issuer
Click Submit

3/ Login screen get a new button "Continue with , click on it
Login on your ADFS portal
Get redirected to Rustdesk, authentication ok but username appears as some generated value (always the same for a user if we delete him and connect again)

Expected Behavior

3/ Get redirected to rustdesk, authentication ok and username as ADFS username and email configured

Additional Context

No response

Start with the RustDesk server OIDC settings and the /api/oidc/callback flow, reproducing the configuration against an on-premises ADFS application group. Check how the callback result is turned into the RustDesk username and personal information; done means an ADFS-authenticated user receives the configured username and email instead of a generated value.
