Hi Dimitrijus,
Thanks for posting here.
I am afraid that Windows RADIUS server can’t accomplish that cos it can only obtain account information from local Security Accounts Manager (SAM) or a Microsoft Windows NT 4.0 domain, or Active Directory® Domain Services (AD DS) but not third party
database:
User account databases
The user account database is the list of user accounts and their properties that can be checked by a RADIUS server to verify authentication credentials and user account properties containing authorization and connection
parameter information.
The user account databases that NPS can use are the local Security Accounts Manager (SAM), a Microsoft Windows NT 4.0 domain, or Active Directory® Domain Services (AD DS). For AD DS, NPS can provide authentication
and authorization for user or computer accounts in the domain in which the NPS server is a member, two-way trusted domains, and trusted forests with domain controllers running Windows Server® 2008; Windows Server 2003, Standard Edition; Windows Server 2003,
Enterprise Edition; and Windows Server 2003, Datacenter Edition.
If the user accounts for authentication reside in a different type of database, NPS can be configured as a RADIUS proxy to forward the authentication request to a RADIUS server that does have access to the user
account database. Different databases for AD DS include untrusted forests, untrusted domains, or one-way trusted domains.
