SAML authentication results in a 401 error for all users. The SAML authentication attempt is logged as FAILED in the <APPIAN_HOME>/logs/login-audit.csv file. However, Appian authentication works as expected.
<APPIAN_HOME>/logs/login-audit.csv
This issue may happen if a wrong date or time is set on the servers involved in the authentication process, which will invalidate the SAML request/response.
This has been observed in cases where server hosting the Appian application has the server time off by a minute or more.
Ensure that the servers involved in the authentication process are configured with the correct time.
This article applies to all versions of Appian.
