Sectona PAM supports JIT for Unix servers. Here 'Enable/ Disable' and the 'Provision/ Deprovision' functionality remains the same. However for 'Access Based Elevation', the default group to which the access is elevated to is 'Administrators'. This can be changed under the following path - Sectona → Manage → Accounts Lifecycle → Configuration → Operating Systems → Asset Type = Unix Based

Here the default group is 'root' but this can be changed to any other group.
