Postgresql groupreply problem

Hello @ all,

I want to change the user MAC-authentication with an HP-Switch from the users-file to postgresql. The first thing is, that I have a some lines which check whether it is a Call-Check or not. If not then the radius has to reject this. But I think it's ok if I put this into the users-file. I have written the Cleartext-Password in this file, too, because I get an chap error (chap: ERROR: &control:Cleartext-Password is required for authentication), when I put this into the database.


In the Moment my configurations looks like this:

-------------- users file --------------
DEFAULT Service-Type != Call-Check, Auth-Type := Reject
        Fall-Through = Yes

DEFAULT Cleartext-Password := "xxxXXXxxx"
        Fall-Through = Yes

DEFAULT
        Egress-VLANID := 0x3200005C   #<-- check in server.conf; reject if it's the same


-------------- server.conf --------------
...
authorize {
        suffix
        if (Realm != "NULL") {
                reject
        }
        chap
        files.sw-hp-mac-v3
        sql.sw-hp-mac-v3
        if (reply:Egress-VLANID == "0x3200005C") {
                reject
        }
}


-------------- Database --------------
(Hope that the format is ok. The tables radreply and radgroupcheck are empty)

+----------------------------------------------------------------------+
| radcheck                                                             |
+----+-------------------+--------------------+----+-------------------+
| id | username          | attribute          | op | value             |
+----+-------------------+--------------------+----+-------------------+
|  0 | 00:11:22:33:44:55 | Calling-Station-Id | == | 00-11-22-33-44-55 |
+----+-------------------+--------------------+----+-------------------+

+-----------------------------------------------+
| radusergroup                                  |
+----+-------------------+-----------+----------+
| id | username          | groupname | priority | 
+----+-------------------+-----------+----------+
|  0 | 00:11:22:33:44:55 |       abc |        0 |
+----+-------------------+-----------+----------+

+--------------------------------------------------+
| radgroupreply                                    |
+----+-----------+---------------+----+------------+
| id | groupname | attribute     | op | value      |
+----+-----------+---------------+----+------------+
|  0 |       abc | Egress-VLANID | := | 0x320000E0 |
+----+-----------+---------------+----+------------+



The main problem is that the freeradius does not insert the GroupName in the sql-commands and so there is no correct reply.

Does anyone have an idea?
