[Solved] Problem migrating from 17.3 hotfix E to 18.1 hotfix A with SAML/SSO active

Hello:

I just noticed a bug during the migration of our preproduction environment. Having SSO over SAML active on this environment, after migrating correctly everything without errors with engines/jboss, when we tried to access to appian (it didn't matter which url) I throwed error 500 (couldn't log-in). Also, if we tried to go to the portal login (to login with admin user that is outside of the SSO login rules) using <domain>/suite/portal/login.jsp it throwed 403. Looking at the logs I saw this errors refering the first one to a "normal" SSO log-in try and the second one to the portal log-in:

1. 14:47:52,898 INFO [stdout] (http-0.0.0.0:8443-1) 2018-04-11 14:47:52,892 [http-0.0.0.0:8443-1] ERROR com.appiancorp.security.authz.Forbidden - Error getting user details for authz logging. Proceeding to log with empty user details: java.lang.NullPointerException
2. Null value was assigned to a property of primitive type setter of com.appiancorp.security.auth.saml.service.SamlSettings.rememberIdp.

As you can see in the screenshots attached, there is a new column ( remember_idp ) in the saml_config table in 18.1 that wasn't in 17.3. It was set to NULL by default, causing the NullPointerException in both cases. After setting it to 1, It worked flawlessly.
