During sign-in into ADFS via a browser, there appears to be an "extra re-direct" call to the ADFS WS-Federation/SAML endpoint "/adfs/ls" before sign-in is successful.
Although, the extra re-direct does not cause an issue during sign-on - would like to understand why the extra re-direct is occurring.
Using the term "extra redirect" only because we have several working configurations where login occurs without the redirect.
So my question is what additional configuration in ADFS may be resulting the extra re-direct?
