Single IDp with muliple SP on subdomain with seperate ftp user

[happy123dubey]

Hi All,

I need to authenticate with single IDp(ADFS) with multiple service provider on different subdomains with seperate ftp users means,  a domain a1.example.com can not access files of a2.example.com  and I have installed simpleSAMLphp on a1.example.com and its working file with IDp and sp a1.example.com. I have configure two sp's in authsource.php. How I can include  "simplesamlphp/lib/_autoload.php" in a2.example.com. I do not want seperate simplesamlphp installation for every subdomain. If I need to install seperate instance for every subdomain, what is the use of configuration of multiple SP'.

Any help will be appreciated.

Thanks,

HD

You can specify whatever complicated logic you want on each SPs authproc using core:PHP code, e.g.  https://simplesamlphp.org/docs/stable/core:authproc_php

Thanks Nick, I was asking, for every service provider(web application), do I need seperate simpleSAMLphp instance or only single simpleSAMLphp instance will solve the purpose.

You only need a single IdP. Each service needs to be its own SP.

Got it, but different SP(website under a domain) require seperate simpleSAMLphp installation or SSO can be achieved by single simpleSAMLphp installation for all sundomains?

Either is fine. It's all up to your design of how authentication and authorization is going to work.
