AD Username sensitivity
by Charlie B 10 Sep '08

10 Sep '08

Hello, I just wanted to ask how you guys are dealing with the seemingly case sensitive nature of AD 2003 (Pre-Windows 2000 Username) with radius? Are you guys using a different attribute instead of sAMAccount or a module to lowercase/initial caps the username? Running: freeradius-krb5-2.0.5-2.fc9.i386 freeradius-ldap-2.0.5-2.fc9.i386 freeradius-2.0.5-2.fc9.i386 freeradius-utils-2.0.5-2.fc9.i386 freeradius-libs-2.0.5-2.fc9.i386 samba-common-3.2.1-0.18.fc9.i386 samba-3.2.1-0.18.fc9.i386 samba-winbind-3.2.1-0.18.fc9.i386 samba-client-3.2.1-0.18.fc9.i386 Everything works great except when a user tries to validate with a username case not exactly that of AD. I also realize this is much more a AD issue but I can't find any information as to what I need to change in GP or registry to correct this behavior. A link or your comments would be greatly appreciated. Thanks

Out of memory problem
by Jean Carlos Oliveira Guandalini 10 Sep '08

10 Sep '08

Hello, I am using the version 1.1.7 with authentication / accounting in mysql (rlm_sql). The problem is that the use of memory increasing until it is exhausted: dmesg messages: Out of Memory: Killed process 28272 (radiusd). Out of Memory: Killed process 1149 (radiusd). Out of Memory: Killed process 1155 (radiusd). The problem can only be solved restarting or reloading the radiusd. After restarting, the use of memory back to normal. It is a bug in version? Kernel problem ??? (kernel version is 2.6.15) Thanks Sorry for my english

How to modify dialup.conf for each virtual server?
by Nataniel Klug 10 Sep '08

10 Sep '08

Hello again, Now I have the other question I told in the post before. I have some equipament (wireless) that authenticate the wireless client using MAC over my radius database. I want that in one of my virtual servers I have this kind of authentication. I need it to check MAC address that is, already, in my radcheck table. this is a common user setup into radcheck table: +------+----------+--------------------+----+-------------------+--------+------+ | id | UserName | Attribute | op | Value | numero | obs | +------+----------+--------------------+----+-------------------+--------+------+ | 1613 | nataniel | MD5-Password | := | XXXXXXXXX | 01046 | | | 1656 | nataniel | Calling-Station-Id | == | AA:AA:AA:AA:AA:AA | 01046 | NULL | +------+----------+--------------------+----+-------------------+--------+------+ So, MAC Address is set as "Calling-Station-Id". This is ok for my PPPoE setup but for my access points this is not ok. I need my access point to verify if this MAC here is well listed and not bloked. I use this to blok: +------+----------+--------------------+----+-------------------+--------+------+ | id | UserName | Attribute | op | Value | numero | obs | +------+----------+--------------------+----+-------------------+--------+------+ | 1613 | nataniel | MD5-Password | := | XXXXXXXXX | 01046 | | | 1656 | nataniel | Calling-Station-Id | == | AA:AA:AA:AA:AA:AA | 01046 | NULL | | 1657 | nataniel | Auth-Type | := | Reject | 01046 | NULL | +------+----------+--------------------+----+-------------------+--------+------+ I have to change dialup.conf to meet this options and returno to my access point. This is a common query comming from on of my APs: Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on proxy address * port 1814 Ready to process requests. rad_recv: Access-Request packet from host 172.30.0.142 port 6001, id=1, length=69 User-Name = "00:19:79:0f:98:3d" User-Password = "wireless" NAS-IP-Address = 172.30.0.142 NAS-Port = 0 +- entering group authorize ++[preprocess] returns ok rlm_realm: No '@' in User-Name = "00:19:79:0f:98:3d", looking up realm NULL rlm_realm: No such realm "NULL" ++[suffix] returns noop expand: %{User-Name} -> 00:19:79:0f:98:3d rlm_sql (sql): sql_set_user escaped user --> '00:19:79:0f:98:3d' rlm_sql (sql): Reserving sql socket id: 4 expand: SELECT id, username, attribute, value, op FROM radcheck WHERE username = '%{SQL-User-Name}' ORDER BY id -> SELECT id, username, attribute, value, op FROM radcheck WHERE username = '00:19:79:0f:98:3d' ORDER BY id expand: SELECT groupname FROM usergroup WHERE username = '%{SQL-User-Name}' ORDER BY priority -> SELECT groupname FROM usergroup WHERE username = '00:19:79:0f:98:3d' ORDER BY priority rlm_sql (sql): Released sql socket id: 4 rlm_sql (sql): User 00:19:79:0f:98:3d not found ++[sql] returns notfound rlm_pap: WARNING!

So, where I see "WHERE username = '00:19:79:0f:98:3d' " it should be Attribute. But I need to be sure that this client is not rejected somewhere in the database. Can someone help me?

freeradius version 1.0.x Vs 2.x.x
by Abraham Jacob 10 Sep '08

10 Sep '08

Hi, I have been using freeradius 1.0.5 for captive portal authentication in our internal network. I use mysql as backend for radius and using sqlcounter to check monthly usage. I was trying out freeradius version 2.1.0 and found out that check attribute values from radcheck table being replaced by values from radgroupcheck. For example, sqlcounter is using Session-Timeout = 28800 if I use freeradius version 1.0.5 and Session-Timeout = 14400 if I use version 2.1.0. Debug from 1.0.5: rlm_sqlcounter: Authorized user test, check_item=28800, counter=509 rlm_sqlcounter: Sent Reply-Item for user test, Type=Session-Timeout, value=28291 modcall[authorize]: module "noresetcounter" returns ok for request 2 modcall: leaving group authorize (returns ok) for request 2 Debug from 2.1.0: rlm_sqlcounter: Authorized user test, check_item=14400, counter=509 rlm_sqlcounter: Sent Reply-Item for user akj, Type=Session-Timeout, value=13891 ++[noresetcounter] returns ok radcheck table: +----+----------+--------------------+------------------------------------+----+ | id | username | attribute | value | op | +----+----------+--------------------+------------------------------------+----+ | 7 | test | Crypt-Password | $1$WXkDxOPI$hZadd2xez2Xl7k4asVqOG. | := | | 9 | test | Session-Timeout | 28800 | := | +----+----------+--------------------+------------------------------------+----+ radgroupcheck table: +----+-----------+----------------------+-------+----+ | id | groupname | attribute | Value | op | +----+-----------+----------------------+-------+----+ | 1 | test | Session-Timeout | 14400 | := | +----+-----------+----------------------+-------+----+ radusergroup table: +----------+-----------+----------+ | username | groupname | priority | +----------+-----------+----------+ | test | test | 1 | +----------+-----------+----------+ sqlcounter: sqlcounter noresetcounter { counter-name = sess_timeout check-name = Session-Timeout reply-name = Session-Timeout sqlmod-inst = sql key = User-Name reset = never query = "SELECT SUM(AcctSessionTime) FROM radacct WHERE UserName='%{%k}'" } I have tested this with version 2.0.5 and got same result. Is this the expected behavior in version 2.x.x? Thanks, Abraham

>DEFAULT Auth-Type:= Accept > >in users file. > >Ivan Kalik >Kalik Informatika ISP Thanks for your reply but it's not working, this is my users file: =====BOF===== # # Please read the documentation file ../doc/processing_users_file, # or 'man 5 users' (after installing the server) for more information. # # This file contains authentication security and configuration # information for each user. Accounting requests are NOT processed # through this file. Instead, see 'acct_users', in this directory. # # The first field is the user's name and can be up to # 253 characters in length. This is followed (on the same line) with # the list of authentication requirements for that user. This can # include password, comm server name, comm server port number, protocol # type (perhaps set by the "hints" file), and huntgroup name (set by # the "huntgroups" file). # # If you are not sure why a particular reply is being sent by the # server, then run the server in debugging mode (radiusd -X), and # you will see which entries in this file are matched. # # When an authentication request is received from the comm server, # these values are tested. Only the first match is used unless the # "Fall-Through" variable is set to "Yes". # # A special user named "DEFAULT" matches on all usernames. # You can have several DEFAULT entries. All entries are processed # in the order they appear in this file. The first entry that # matches the login-request will stop processing unless you use # the Fall-Through variable. # # If you use the database support to turn this file into a .db or .dbm # file, the DEFAULT entries _have_ to be at the end of this file and # you can't have multiple entries for one username. # # You don't need to specify a password if you set Auth-Type += System # on the list of authentication requirements. The RADIUS server # will then check the system password file. # # Indented (with the tab character) lines following the first # line indicate the configuration values to be passed back to # the comm server to allow the initiation of a user session. # This can include things like the PPP configuration values # or the host to log the user onto. # # You can include another `users' file with `$INCLUDE users.other' # # # For a list of RADIUS attributes, and links to their definitions, # see: # # http://www.freeradius.org/rfc/attributes.html # # # Deny access for a specific user.

Joker character to allow everyone in a SQL table
by via.lej＠free.fr 10 Sep '08

Hello all ! I'm using a FreeRadius server 1.1.3. It is configured to use a SQL table (which contains some mac addresses to allow user to access to the network or not). This night the SQL table has flushed. Is there some joker characters I can put in the SQL table to allow everyone while I build up the table again ? Or any other way to do that ? Regards, Dav

using sqlcounters
by Alexandre Chapellon 10 Sep '08

10 Sep '08

Hello, I want to setup sqlcounter to prevent users to login once they have reached traffic quota. So i added a new specific sqlcounter in raddbb_dir/sql/mysql/counter.conf, and the name of that counter in the authrorize section. All is as follow: #####counter.conf##### sqlcounter bytesQuota { counter-name = traffic_quota check-name = Max-Traffic sqlmod-inst = mysqldb key = User-Name reset = hourly query = "SELECT SUM(acctinputoctets + acctoutputoctets) FROM radacct WHERE UserNmae='%{%k}'" } #####virtual_server##### authorize { ... bytesQuota } #####users file##### scott Mana-Traffic = 101, Cleartext-Password := "tiger" whenever i launch freeradius -X I get the folloawing error: /etc/freeradius/users[205]: Parse error (check) for entry scott: Invalid octet string "101" for attribute name "Max-Traffic" Line 205 is the line where user scott is defined in users files. I have tryed setting up my own dictionnary (which i think shouldn't be needed) with the Max-Traffic attribute defined as interger VENDOR ME ATTRIBUTE Max-Traffic 1 integer But that doesn't help. I have read all over the web that sqlcounter with mysql are considered as stable enough for production , so am quite surprised of this issue... Any idea?
