What mechanisms are available for user provisioning in the SaaS instance of Agile Central, if using SSO?
Unfortunately there are no options for provisioning of users (enable/disable/configure) in Agile Central through SSO. An enhancement request or idea for this has been posted on Ideas.rallydev.com (https://ideas.rallydev.com/ideas/D3721). We encourage you to vote for this and add your feedback.
However new users can be created using the Excel add-in to import those users. It is likely that customers would need to manually adjust or add Project permissions after the users are imported since the import can only provide limited field values and choices for users.
Alternatively the following url links to a GitHub script that can also be used to import or manipulate users. Please be aware that Agile Central Support does not support or maintain scripts on the GitHUb repository. (https://github.com/RallyTools/Rally-User-Management)
