Objet : RE: check-item NAS-IP-ADdress & Calling-Station-ID with openldap
Hi All,
I want to use FreeRadius to administer network equipement. I use also OpenLDAP to stock information about users. FreeRADIUS and OpenLDAP are installed on the same server FreeBSD 7.0.
I contact a Network equipement (like catalyst cisco 2950 v12.1) with putty (ssh/telnet).
To resume :
Windows XP -> ssh or telnet -> Cisco 2950 (client radius/authenticator/NAS) -> EAPoRadius (I suppose) -> FreeRADIUS & OpenLDAP
For the moment, I don't install/configure supplicant on the Windows XP, I don't know if it's require because I don't want to use FreeRADIUS to auhtenticate my Windows session. I have an active directory to do this.
I configure slapd.conf, radius.conf, clients.conf, module ldap etc ... and it's works. And now I would like to add some check-item like NAS-IP-Address and Caliing-Station-ID. But I don't succeed :s, I use checkval to do this.
I have 2 questions :
- Why my calling-station-id in the request is a IP and not a MAC ?
- When I authenticate on the cisco 2950, I have in my log « rlm_checkval: Item Name: NAS-IP-Address, Value: À¨ » instead of 192.168.0.50, what is the problem ???
I think I have numerous problem, If you see one of them, could you inform me ? I am a novice with freeradius (and openldap also :s ). I could give you all information you need to help me to fix my problem.
Thanks for your help,
Regards
Francçois MEHAULT
On my cisco 2950 :
aaa new-model
aaa authentication login default local group radius
aaa authorization exec default group radius local
aaa authorization network default group radius
My ldap.attrmap :
checkItem Calling-Station-Id radiusCallingStationId
checkItem NAS-IP-Address radiusNASIpAddress
Extract of my openldap :
