Had a question on SAML users and the SCIM tool.

We have a customer that is currently using a mix of Windows accounts and SAML users.  The reason is that some of the users are external users (not on their domain).  They are able to set those external users up in Entra and then we manually add them as SAML users in the LFDS.  This is all seems to be working fine.

However, they are looking to add more users and it will start to be become a bit more of a process to manage the licenses.  Its my understanding that since there is not an option to sync, the customer needs the SCIM tool so that it can pull those users from the Entra group and then assign them a SAML license/user. 

First, is the above assumption correct?  Also, they are wanting to have all their users start to use SAML (as the windows accounts are using windows auth).  If they add the current windows users to the Entra group and then the SCIM tool syncs them up, do they become SAML users in LFDS or do they stay windows accounts?  Don't have all that much experience with the tool and wonder how it would impact users that are already in place.

Thanks,

Chris
