Fixed an issue where some users could not log in after update when using SAML SSO for authentication. Alation recently added support for using HTTP POST binding with SAML SSO. All customers were previously using Redirect binding because Alation did not support POST binding. Many configurations allow for automatically selecting POST binding if available. This caused existing instances to switch over and in some cases caused authentication failures blocking users from logging in. Now, Alation has changed SAML SSO support to always force defaulting to Redirect binding. So existing installations integrated with SAML SSO should work in the same way they did before. Those customers wanting to use POST binding can change the configuration alation.authentication. saml.force_redirect_binding to False.

The Curation progress bar on the Stewardship Dashboard now gets updated properly when the user adds or removes Title, Description or Custom Fields. This is applicable to such object types as Data Source, Schema, Table, and Attribute.

Fixed an issue where in some environments the replication service on the secondary server would not start. This prevented replication of configuration files. If your replication started without error this does not impact your installation.

Users were able to extract only 50 schemas when Metadata Extraction was performed for Google BigQuery data source. Now, users can extract all schemas.

Miscellaneous Other Fixes

  • Fixed a bug where Compose queries against Kerberized Hive data sources using HTTP transport would throw an error if the result set was longer than 999 rows. Now, there is no limit on the result set so query execution will be successful for all rows in the set.

  • Fixed an issue where email integration would stop working on HA Pair configuration after failing over to the secondary server. If a customer was using a custom email integration instead of the built-in email server and they failed over to the secondary server, then users would no longer receive emails.
