Password Problem
by Lawrence Shafer 04 Aug '06

04 Aug '06

I set up FreeRadius/MySQL and ChilliSpot and created a test user with the included DialupAdmin. I then connected to the server radius nic and was directed to the login page and typed my username and password and was rejected. I then went to the DialupAdmin user edit and checked the password and it failed, so I changed the password and the PW check failed again. I even tried a new user and had the same problem. Everything else seems to be working correctly. What could the problem be? Could the password DB be missing in MySQL? How do I check? I'm a noob to all of this (FreeRadius, MySQL) but not to linux. I have it installed on gentoo if that makes any difference. I also tried directly inserting a user into the DB with mysql> INSERT INTO radcheck (UserName, Attribute, Value) VALUES ('lawrence', 'Password', 'le'); Query OK, 1 row affected (0.00 sec) and had the same problem Thanks for your help, Lawrence Shafer

monitoring freeradius with snmp
by Andy Ford 04 Aug '06

04 Aug '06

Hi, I have a requirement to monitor freeradius with snmp. According to the freeradius web site and other sources I've done the following... 1. compiled freeradius with the '--with-snmp' option 2. modified the freeradius snmp.conf file to include smux_password = verysecret 2. modified the radiusd.conf file with snmp = yes $INCLUDE ${confdir}/snmp.conf 3. modified the net-snmp snmpd.conf file to include smuxpeer .1.3.6.1.4.1.3317.1.3.1 verysecret 4. started the radiusd and snmpd daemons. When I do an 'snmpwalk -v1 -c public localhost system' I get the 'system' info from the MIB (as expected). When I walk enterprises.3317 I get nothing. I didn't actually expect to get much as I have a huge gap in my knowledge which is the smux. I'm not sure how it works or how I implement it successfully. Has anyone implemented an smux or monitoring freeradius with snmp. If you have, It would be great if you would impart with any knowledge you may have so I can sort this out.

Consolidating radius Servers
by Dourty, Brian R. (IATS) 04 Aug '06

04 Aug '06

We currently have two load-balanced pairs of freeradius servers. One set supports our Dial-up/VPN customers and the other set supports our 802.1x wireless infrastructure. I'm wondering if it is possible to serve both sets of customers using one set of radius servers. How would we get the radius server to use the LDAP module for the dial-up/vpn users and the eap module for the 802.1x users? thanks, Brian Dourty System Administrator - Team Lead IAT Services University of Missouri - Columbia 573-882-1035

freeradius function
by Lin Richardson 04 Aug '06

04 Aug '06

Hello All, Is there a succinct way to describe how freeradius processes requests? sort of a high level overview? Like: The radiusd daemon is running and receives a valid request It parses out attributes passed in with the request ... and then... That is the point where I'd like some clarification... what files does it parse as it continues, etc...? Any takers? If this is documented somewhere and I missed it, I apologize. Regards, Lin Richardson

noob with some questions
by P. K. 04 Aug '06

04 Aug '06

Hi All, I've been setting up my College's first FreeRadius server and I've been having a hard time wrapping my brain around the config with the documentation that is available. If you'll bear with me here through this super long post, I'll go into more depth. What I'm trying to do: I want to configure FreeRadius to Authorize a user against an LDAP directory based on IF that user has the following values: *edupersonprimaryaffiliation: *STAFF AND *psadminarea*: BUSINESS - SMEAL COLLEGE _OR_ *edupersonprimaryaffiliation: *Faculty AND *psadminarea*: BUSINESS - SMEAL COLLEGE If the user's values don't match either of these two condition, they are rejected. If they match either, then they are authenticated agains a kerberos server. I've got the basic configuration working in that FreeRadius will go out to the LDAP directory (right now it just seems to check if the attribute exists but does not make a judgement on it) and then it will go out to the Kerberos server and Authenticate. I want to now add the conditions I stated above but I'm a bit lost this point. At first I thought that this was something the CheckValue module should handle, then I thought maybe it should just be a part of the filter in the LDAP module, then I thought about maybe the values need to be in the dictionary files. At this point, it became apparent that I simply don't understand how FreeRadius handles itself. It is not apparent to me how or where FreeRadius makes its decisions on conditional values. This is where I hope some of you can help. I really like FreeRadius in that it is obviously a quality product, but as it is with the documentation and my lack of Radius experience, I just can't seem to get at the last piece of this puzzle. Right now, I have the following settings (with debug output further down) radiusd.conf, LDAP module: ldap { server = "ldap.psu.edu" # identity = "cn=admin,o=My Org,c=UA" # password = mypass basedn = "dc=psu,dc=edu" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" # base_filter = "(objectclass=radiusprofile)" # set this to 'yes' to use TLS encrypted connections # to the LDAP database by using the StartTLS extended # operation. # The StartTLS operation is supposed to be used with normal # ldap connections instead of using ldaps (port 689) connections start_tls = no # tls_cacertfile = /path/to/cacert.pem # tls_cacertdir = /path/to/ca/dir/ # tls_certfile = /path/to/radius.crt # tls_keyfile = /path/to/radius.key # tls_randfile = /path/to/rnd # tls_require_cert = "demand" # default_profile = "cn=radprofile,ou=dialup,o=My Org,c=UA" # profile_attribute = "radiusProfileDn" access_attr = "psadminarea" # Mapping of RADIUS dictionary attributes to LDAP # directory attributes. dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 # # NOTICE: The password_header directive is NOT case insensitive # # password_header = "{clear}" # # Set: # password_attribute = nspmPassword # # to get the user's password from a Novell eDirectory # backend. This will work *only if* freeRADIUS is # configured to build with --with-edir option. # # # The server can usually figure this out on its own, and pull # the correct User-Password or NT-Password from the database. # # Note that NT-Passwords MUST be stored as a 32-digit hex # string, and MUST start off with "0x", such as: # # 0x000102030405060708090a0b0c0d0e0f # # Without the leading "0x", NT-Passwords will not work. # This goes for NT-Passwords stored in SQL, too. # # password_attribute = userPassword # # Un-comment the following to disable Novell eDirectory account # policy check and intruder detection.

NAS-ID missing in 1.1.2?
by Drew S. Dupont 04 Aug '06

04 Aug '06

Has this attribute been intentionally left out of 1.1.2? In my 1.1.1 build it works as a user attribute in the users file. But in 1.1.2, it complains about not finding it. It is not listed in any dictionary in 1.1.1 or 1.1.2 so I would assume it was internal to the server itself. Fri Aug 4 06:22:51 2006 : Error: /etc/raddb/users[20]: Parse error (reply) for entry tester3: Unknown attribute "NAS-ID" Fri Aug 4 06:22:51 2006 : Error: Errors reading /etc/raddb/users Fri Aug 4 06:22:51 2006 : Error: radiusd.conf[1047]: files: Module instantiation failed.
