freeradius-pre2 - hostname lookup
by Edvin Seferovic 10 Dec '07

10 Dec '07

Hi, my freeradius does always a hostname lookup although hostname_lookup = no AND if the client is not found in the clients.conf... Mon Dec 10 05:29:43 2007 : Error: Trying to look up name of unknown client 172.19.10.160. Mon Dec 10 05:29:43 2007 : Auth: Login OK: [00:09:34:14:ad:57] (from client UNKNOWN-CLIENT port 24 cli 00-09-34-14-ad-57) The client is entered in the virtual server config => server my_server { client clientname { ... } } ! Bug or just a random feature ? Regards, E:S

HELP! testuser works, but local unix user dosn't! - WPA/WPA2 PEAP

Hi, I use freeradius 1.1.7, and my client pc runs windows Vista. I've set up a testuser with a clear-text password in the users file - which works:-). I can connect using the testuser with WPA/WPA2, PEAP, TTLS without problems. But when I try to connect using the local unix users it dosnt work:-((, what am I doing wrong?

You don't do attribute mappings.

FW: MS-CHAP-v2 and CHAP with different passwords in LDAP
by Edvin Seferovic 08 Dec '07

08 Dec '07

Hello list members, before somebody yells "not again" - I just wish to ask if it is possible to use MS-CHAP and CHAP authentication with a LDAP backend which contains clear-text passwords as well as NT-Password ( used for MS-CHAP ) ??? Alan - yes/no answer please :) If positive - can somebody give me an example of attribute mapping to ldap for both ( MS-CHAP and CHAP ) to work ? My setup with LDAP as backend is working with a mapping of NT-Password to sambaNTPassword like this : checkItem NT-Password sambaNTPassword MS-CHAP works just fine ! For CHAP I added password_header = "{clear}" password_attribute = "userPassword" password_radius_attribute = "User-Password" to the LDAP module configuration. But unfortunately chap module doesn't like my clear-text password ( stored in userPassword ) for authentication :( How else can I say CHAP where to look for the clear-text password. Any hints please ? TIA ! Regards, E:S

Newbie question
by Monah Baki 07 Dec '07

07 Dec '07

Hi all, I am new to freeradius and I want to know if it's possible to perform the following. I provide for multiple people access to the internet via a proxy server with authentication (htpasswd), server is FreeBSD. I want to deny them access after 1 month. I was wandering if freeradius can work with the htpasswd password file, and then deny them access after 1 month. Thank you
