Radius Dynamic Vlan assignment with ldap attribut
« on: January 25, 2022, 11:32:55 am »
Hello,


I use "Opnsense" with the FreeRadius module and the Ldap option. I want to automatically assign a particular Vlan based on a given Ldap attribute.

I followed this documentation :

https://www.reddit.com/r/OPNsenseFirewall/comments/huhmuw/comment/hqeraav/?utm_source=share&utm_medium=web2x&context=3

I need to make the attribute dynamic Tunnel-Private-Group-Id

Thanks

The attributes which contain e.g. the VLAN ID are not set up on the Freeradius server or the OPNsense.

You have to store the attributes in your LDAP.
For this you will most likely have to import a schema.

Here is the LDAP schema of my OpenLDAP configuration. Maybe it helps you:

After importing this schema you shopuld be able to attach the attribute to your user.

objectClass: radiusprofile
radiusTunnelType: VLAN
radiusTunnelMediumType: 6
radiusTunnelPrivateGroupId: 100     #The VLAN ID the user should get
