      • You can assign groups from IDP to users created through SSO by adding the name of the group attribute that contains the IDP groups in the SAML response in the Group Attribute field in the plugin configuration. You can find out the group attribute name by performing the test configuration from the test configuration button under the I will do manual configuration tab.
        • Jenkins SAML Single Sign On (SSO) Jenkins SAML Single Sign On (SSO)
      • To assign a default group to users created through SSO add the group name in the Assign group to new Users option. Multiple groups can be added using a comma (,) separator.
      • Group Mapping allows you to align user groups from your identity provider (IdP) with the corresponding groups in Jenkins. This is especially useful when the group names in your IDP differ from those in Jenkins. By configuring group mappings, you can ensure that users are assigned the correct roles and permissions within Jenkins based on their IdP group membership.

        For example, if your IdP group is named "idpGroupName" but the corresponding group in Jenkins is "jenkinsGroup", you can map idpGroupName to jenkinsGroup to maintain consistent access control.
