CARSI will retrieve the metadata from eduGAIN, you need to add a SP in CARSI Online Helpdesk, providing SP name, description, service address, SP EntityID which can be located in eduGAIN metadata feed. Please refer to 1. eduGAIN SP接入(Joining CARSI for eduGAIN SP) for details.
2. 自建Shibboleth SP接入 (a new Shibboleth SP)：
这种方式适用于应用系统已经支持Shibboleth认证、已实现Shibboleth SP、但尚未加入eduGAIN的情况，或适用于希望新建/改建应用系统的认证授权部分以支持CARSI接入的情况。此方式需SP服务提供单位自主安装Shibboleth SP来保护待接入的应用系统，并将该SP接入到CARSI联盟。详细流程参见： 2. 自建Shibboleth SP接入(Joining CARSI for Shibboleth SP)。
This is a new Shibboleth SP, thie case is suitible for creating/updating the login part of your existing application to support CARSI access. You need to install and configure your Shibboleth SP to protect your application, and use this Shibboleth SP to join CARSI. Please refer to 2. 自建Shibboleth SP接入(Joining CARSI for Shibboleth SP) for details.
3. 使用CARSI提供的SP OAuth网关接入(join CARSI through the CARSI SP OAuth gateway)：

Join your existing application into CARSI through CARSI SP OAuth gateway. SP+OAuth gateway acts as the Shibboleth SP, your application dose not need a dedicated Shibboleth SP. In this case the changes to your existing application are limited, your application should support OAuth 2.0 (acts as an OAuth client). Please refer to 3. 通过CARSI SP OAuth网关接入(Joining CARSI for OAuth SP) for details.
