Group checking in ldap authorization

[Robert Roll]

 The below is out of the  .../share/doc/freeradius/rlm_ldap  

 Note that it shows the Ldap_Group variable being set in the users file, but
I'm assuming it should not really matter where it gets set ?

     DEFAULT	Ldap-Group == "cn=disabled,dc=company,dc=com"

Also, the part about the specific instance Ldap-Group is:

Also if you are using multiple ldap module instances a per instance
Ldap-Group attribute is registered and can be used. It is of the form
<instance_name>-Ldap-Group. In other words if in radiusd.conf we
configure an ldap module instance like ...

 Note, I do not want to test for Ldap_Group, I want to be able to actually
set it so it is used within the  ldap module ?


Thanks,

Robert

GROUP SUPPORT: The module supports searching for ldap groups by use of the
Ldap-Group attribute. As long as the module has been instanciated it can be
used to do group membership checks through other modules. For example in the
users file:

DEFAULT	Ldap-Group == "disabled", Auth-Type := Reject 
	Reply-Message = "Sorry, you are not allowed to have dialup access"

DNs are also accepted as Ldap-Group values, i.e.:

DEFAULT	Ldap-Group == "cn=disabled,dc=company,dc=com", Auth-Type := Reject
	Reply-Message = "Sorry, you are not allowed to have dialup access"



Also if you are using multiple ldap module instances a per instance
Ldap-Group attribute is registered and can be used. It is of the form
<instance_name>-Ldap-Group. In other words if in radiusd.conf we
configure an ldap module instance like:

ldap myname { [...] }

we can then use the myname-Ldap-Group attribute to match user
groups. Make sure though that the ldap module is instantiated *before*
the files module so that it will have time to register the
corresponding attribute. One solution would be to add the ldap module
in the instantiate{} block in radiusd.conf

Where did you get this from? It's totally wrong.

Try:

   if (Ldap-Group == chemVLAN) {
   }

Ldap-Group (or modname-Ldap-Group) is a "virtual" attribute, that will
perform the group membership check when you run a comparison.
