No particular error will appear, but the verified SSO session should allow users access without signing in through the Arctera Unified Platform login gateway.
This is typically due to a digital signature being excluded from the Okta SAML response to the Arctera Unified Platform authentication servers.
Ensure the following fields are set accordingly in the Okta administration console, under settings for the Arctera Unified Platform application:
Response - Unsigned
Assertion Signature - Signed
Signature Algorithm - RSA_SHA256
Digest Algorithm - SHA256
Note: All SSO providers must provide signatures in responses to SAML requests by Arctera Unified Platform, or those requests would fail. This particular article focuses on the proper implementation of signatures in those responses with Okta.
Organizations using Okta for Single Sign-On (SSO) functionality with Arctera Unified Platform could be re-directed to the Login Gateway for any Arctera Unified Platform web pages such as Personal Archive, eDiscovery, or the Management Console.
