Windows: TBD

Setup EntityID for SP. Note the entityID for the SP is _NOT_ a URL. It is a unique string that identifies your SP and is usually based off of the hostname of the system. It may also be a CNAME for the system.

Linux:

[root@idmt-1 shibboleth]# hostname
idmt-1.alaska.edu
[root@idmt-1 shibboleth]# pwd
/etc/shibboleth
[root@idmt-1 shibboleth]# vi shibboleth2.xml
    <!-- The ApplicationDefaults element is where most of Shibboleth's SAML bits are defined. -->
    <ApplicationDefaults entityID="https://idmt-1.alaska.edu/shibboleth"
                         REMOTE_USER="eppn persistent-id targeted-id">

        <!--

Windows: TBD

Start Apache/IIS and Shibd and check function.

Email SP metadata to iam@… and request integration with UA IdP. Once the metadata is registered with the UA IdP integration can be tested at the https://idmt-1.alaska.edu/secure test URL that is configured by default with most installations.
Decide which attributes your application will need to authorize access then email iam@… and request those attributes be released to your SP from the UA IdP.
