System for Cross-Domain Identity Management (SCIM) is a standard protocol/API for user provisioning. SCIM is now supported by most major identity providers, including but not limited to Azure AD, Okta, OneLogin etc.
SCIM is a REST-like protocol and works over HTTP(S). The identity provider sends provisioning instructions to registered applications whenever changes occur by calling REST endpoints in the provisioned application (e.g. Jira or Confluence). This can be far more efficient than client-initiated synchronization/snapshotting, as only actual changes need to be transmitted. SCIM is therefore especially recommended for large user directories.
Kantega SSO primarily supports SCIM version 2. The older SCIM v1.1 protocol (legacy) is supported and tested for use with Okta's on-prem provisioning agent, and SCIM v1.1 may also work for other v1.1 providers, we cannot guarantee it and do not officially support it.
SCIM support is currently not available in the Bamboo and Fisheye/Crucible versions of KSSO, nor is it being actively pursued at the moment. Please get in touch at atlassian.support@kantega.no and add your vote if you would like to see this functionality.
