How can I send the Secondary Emails with the SSO callback?
I’m using this PHP library:
Or how to add Secondary Emails to an user manually?
I really need this as well.
On my website, I’ve got multiple emails linked to one account. The user can use any one of them to connect.
When the user logs in to my platform, I also log him on the forum.
When he uses a different email than his main one, even though I specify his discourse ID and Username, Discourse creates a brand new user for that email. 
The original question here is still unaddressed. As far as I can tell
(1) the SSO sync calls do not parse secondary emails
(2) secondary emails cannot be specified on the user by API using the /u/{username}/preferences/email route, if the “email editable” setting is not enabled, which is required for the “auth overrides email” setting typically used with sso.
This is unfortunate, as secondary emails are very useful for identifying inbound email and I have them on my sso provider. There seems to be no way to provide them to Discourse.
I suppose a very hacky workaround is
(1) to not use “auth overrides email” and instead use the user api not the sso api to set the user email.
(2) hide the email editing ui using a theme component
@sam is this pr-welcome for a proper fix to allow alternate emails to be set by discourse connect?
有人解决过这个问题吗?我们使用 SSO,提供商支持辅助电子邮件。但是,如果用户使用该辅助电子邮件登录,Discourse 会为用户创建一个新帐户。我们如何才能只更新现有用户的信息,添加辅助电子邮件?
关于这个主题有什么新闻吗?
是否计划允许从 SSO 同步辅助电子邮件?
