Dear list, My first time I write on the mailing-list. I hope not boring or not already answered thousand of times. I would like to setup a classical radius with rlm_ldap authentication module. The auth works as expected when I add attribute on the user side OR in profile section with the default value. My question is, how I can handle vlan with group dynamicaly. I seen some response/thread that put each group in post-auth {}. But I would like to have all information / matching from LDAP directly not in config file. Do you have some input / docs to do this ?
