Did you install ActiveVOS at the same time as MDM, or did you do the MDM and ActiveVOS separately? From what I've read before on the forums, best practice is to do it at the same time so items like the identity service and the OOTB workflows are loaded into the ActiveVOS configuration.
Actually has you reinstall MDM (in a limited manner) if you want to install ActiveVOS after the MDM installation.
Hope this helps!
I have installed ActiveVOS along with MDM installation.
yes, you need to install activevos along with MDM installer.
If activevos is not installed with mdm and mdm is not showing in identity provider dropdown, please follow below kb to address this issue:
You can also try to execute the post-install in MDM side and provide a new ActiveVOS installation directory (or you can rename the current to backup). Ideally, running a new post-install in a new directory will take care of everything that ActiveVOS and MDM integration needs.
If you are still running into issues, you might want to check the post-install logs.
