I want to use grafana’s saml authentication，Refer to the configuration of the official document, but I found that the saml authentication interface cannot be popped up normally after the configuration，My configuration
[auth.saml]
enabled = true
private_key_path = “/root/certificate/8133341__xxxx.key”
certificate_path = “/root/certificate/8133341__xxxx.pem”
idp_metadata_url = “https://sso.xxxxx.cn/saml.php?_m=saml&_a=get_idp_metadata”
assertion_attribute_name = DisplayN：ame
assertion_attribute_login = Login
assertion_attribute_email = Email
assertion_attribute_groups = Group
The log error is as follows：
logger=server t=2022-10-21T10:02:25.51736581+08:00 level=info msg=“Writing PID file” path=/var/run/grafana/grafana-server.pid pid=16589
