Hello all, First of all, sorry for my bad english; so I'm going to try explaining as simple as possible... so let me know if you dont undestand what I say I found a post here which is nearly the same as my problem : http://lists.freeradius.org/pipermail/freeradius-users/2010-July/048002.html I need to create multiple SSID in a school. On my server, I can create virtuals VLAN and attrib a DHCP server for each. My APs are able to manag many SSIDs and I can attrib one different VLAN to each SSID. I made a test and, according to the SSID I connect, I receive a different IP addres The freeradius on my server is version 3.04. It's connected to a LDAP server. Everything is working fine; people can connect to the SSID using their user/password. But now, I'd like that some users can only connect to specific SSID/VLAN ; for example, I'd like to create a Teachers SSID and only user belonging to group 'teachers' (in my ldap server) can connect to it. Is possible to do that ? On my server, each virtual VLAN has it's own IP address ; could I use it for my authentication ? As i'm completely a beginner in the freeradius world,,, sorry if my question is stupid Per advance, thanks to all for your help
