FreeRadius Authentication against AD or AD LDS (LDAP)

Considering that LDS will still be running Active Directory, give your reception login(s) the permission to administer the Guest-Network OU (i.e. add/delete/edit users), and continue to use the NTLM authentication you use with the primary AD.

Active Directory uses MS-CHAPv2, so using the mschap and ntlm modules as per standard FreeRADIUS wiki articles on AD authentication should be sufficient to be able to authenticate the users in your LDS.

Subject: FW: FreeRadius Authentication against AD or AD LDS (LDAP)


I'm looking for a solution to realize a FreeRadius Server, which can Authenticate against primary a AD and as second method against AD LDS (Lightweight Directory from Windows).
We want for our WLAN, that in the Guest-Network employees can use their AD-Login (I already implemented that with ntlm_auth and it works) and also guests can use this network but their login should be in a AD LDS (LDAP), which can be edited by our reception. I would prefer not to store the password for the guests as Cleartext. Is this possible?
How could I realize that with FreeRadius?

Thanks in advance
