As the habit, client’s used to applying whr to redirect to the connection on ADFS like this:

However, the whr usage is applied by the following rules:

1. uuid: contains the value of the preferred connection. Example: whr=uuid:6D37275A-CDD3-4D20-BB39-D595D9D540AA
2. EntityIdentifier: only available for WS-Federation and SAML 2.0 authentication connections. Example: whr=urn:https://dev.safewhere.local/runtime/
3. name: connections’ names. Example: name:Username & password

In this situation, the client can update its value to: name:https://saml.test-nemlog-in.dk/
