@DevOpserzhao Casdoor already defined some built-in attributes like Name, Email, DisplayName, etc. You should not add them again in the "SAML attributes" table in application edit page like: https://door.casdoor.com/applications/built-in/app-built-in#:~:text=POST%20binding%20%3A-,SAML%20attributes,-%3A

Built-in attributes:

casdoor/object/saml_idp.go

Lines 91 to 104 in c532a5d

	email := attributes.CreateElement("saml:Attribute")
	email.CreateAttr("Name", "Email")

	email.CreateElement("saml:AttributeValue").CreateAttr("xsi:type", "xs:string").Element().SetText(user.Email)
	name := attributes.CreateElement("saml:Attribute")
	name.CreateAttr("Name", "Name")
