How to configure Grafana&Keycloak so that grafana can use Keycloak's username instead of email as Grafana's login name?

[zhouchi]

I created a user in Keycloak, its Username is myuser and its Email is myuser@xx.com.

I then successfully logged into Grafana with this user，but when I logged out from Grafana and then logged into Grafana with admin user again, I found a problem, navigate to Server Admin → Users sub-menu, I noticed that although Grafana created a new user, but it used the email address instead of the username as the login name, how can I get Grafana to use the username ‘myuser’ instead of the email address ‘myuser@xx.com’ as the login name?

The following is my Generic OAuth in grafana.ini
#################################### Generic OAuth ##########################
[auth.generic_oauth]
enabled = true
name = OAuth
allow_sign_up = true
client_id = grafana
client_secret = 553fb17e-a61d-486c-98c0-eb2db0a3eb4f

Hi,

Can you show the configuration of the grafana client ?
Have you used an attribute to link the user with the client?
Have you modified anything else in grafana.ini?

Thanks and regards.

Simply set login_attribute_path to preferred_sername:
login_attribute_path = preferred_username
