Placing IdP metadata information within Adeptia Suite allows to read the file from the particular location.
Depending upon the IdP server you are using (for example, ADFS, PingFederate), download the IdP server metadata file, rename it to idp.xml and place it at the …/<AdeptiaInstallFolder>/etc/saml.
In case of SSO Circle, by default, idp.xml is available at …/<AdeptiaInstallFolder>/etc/saml.
Once you place the file successfully, next step is to map the matching fields of IdP user in Adeptia Suite.
