When attempting to use the Appian for Android application to log into an Appian environment using SAML authentication, the message "Untrusted site, unable to login" appears:
This message indicates that the Identity Provider's log-in page is either using a self-signed SSL certificate, which is by default not trusted by the Android application, or not presenting the full SSL certificate chain.
Note that the SSL certificate used by the Identity Provider is not the same certificate as the Service Provider signing certificate uploaded into the Admin Console. Environments utilizing SAML for authentication with a self-signed Service Provider signing certificate can be accessed using the Appian for Android application.
The Identity Provider needs to be updated to utilize an SSL certificate signed by a trusted Certificate Authority, and configured to present the full certificate chain. This is encryption best practice and recommended particularly for Identity Providers used in production Appian environments.
