Hi, I am trying to get FreeRadius to work with Heimdal Kerberos. What I use: Ubuntu 8.04 FreeRadius 1.1.7-1build4 Heimdal-kdc 1.0.1-5ubuntu4 I have installed Heimdal Kerberos and get tickets. My next step is to get FreeRadius to work with Heimdal and then logging in to my HP-Switch using FreeRadius. I have done the following: # Heimdal Kerberos information REALM = ONE.COM HOST = rofe # In Heimdal Kerberos kadmin -l kadmin> add radius kadmin> ext_keytab --keytab=/etc/krb5.keytab radius kadmin> add rofe # Installing FreeRadius apt-get install freeradius freeradius-krb5 # Added the following in /etc/freeradius/radiusd.conf # In the authenticate section Auth-Type Kerberos { krb5 } # In the modules section krb5 { # keytab containing the key used by rlm_krb5 keytab = /etc/krb5.keytab # principal that is used by rlm_krb5 service_principal = radius/rofe.one.com } I have followed what documentation I could find; http://wiki.freeradius.org/Rlm_krb5 # Then I configured my HP-Switch: radius-server host 192.168.212.93 radius-server key <key> # As key I used the principal radius password - correct ? aaa authentication ssh login radius local aaa authentication ssh enable radius local aaa authentication telnet login radius local aaa authentication telnet enable radius local aaa authentication login privilege-mode # Then I tried to login using telnet telnet 192.168.212.4 # Gets prompted for username and password and uses principal rofe and my password but gets this error: Can't reach RADIUS server 192.168.212.93 I can ping 192.168.212.4 from the HP-Switch. I don't know what to do or where to look - I'm stuck! - Ronni
