modules instance name restrictions
by Thibault Le Meur 24 Mar '09

24 Mar '09

Hi, I recently came up with a small issue concerning modules instances name (especially when they set Auth-Type). * I defined my own pap module with the name 'pap-myorg' and expected it to set Auth-Type to PAP-MYORG, but in fact it wasn't setting the Auth-Type at all (moreover I saw no notice in the log about not beeing able to set the Auth-Type). * I changed the instance name to 'papmyorg' and now the module sets the Auth-Type to PAPMYORG. I tried to find in the doc where the restrictions on module instances names were defined, but didn't found any reference to this. And given the fact that some standard modules have specific chars such as '_' or '-', I thought there was little constraints. Is there any module instance naming convention written somewhere in the provided documentation (or online)? Maybe be it could be interresting to have a warning in the radius debug log in order to notice the administrator that Auth-Type wasn't set due to module naming restrictions? Best regards, Thibault

PAM-Radius authentication issue on Ubuntu 7.4: can not authenticate SSH users not present in /etc/passwd
by Hu, Fengliang (Procurve Networking) 24 Mar '09

24 Mar '09

Hi, I was trying to find a PAM-Radius mailing list and it seems that this is the best one. A Ubuntu 7.4 box needs to be configured such that SSH users will be authenticated against an external FreeRadius server. FreeRadius server version is 1.1.7-1build4. The Ubuntu box uses OpenSSH 4.3-p2 and /etc/ssh/sshd_config is set to "UsePAM yes". I downloaded PAM_Radius 1.3.17. Below is the procedure that I use Radius to authenticate a user in /etc/passwd (/etc/shadow doesn't have the password for that user). 1. FreeRadius server configures its clients.conf and user file to include a new user called "test1". 2. On my Ubuntu 7.4 box, add a user with command "useradd" to add a user "test1" but don't set a password. So the user "test1" on the Ubuntu box will be inactive. 3. Configure /etc/pam.d/ssh on the Ubuntu box to use "auth sufficient pam_radius_auth.so" 4. Also update the /etc/raddb/server on the Ubuntu box to point to the remote Radius server IP. 5. Try ssh test1@ubuntu box and it worked. Also monitored the Free Radius logging and it did show that the Access-Request packets went to Radius server. So step 1-5 worked well for me. Note that at step 2, the user account to be authenticated is added to /etc/passwd. The issue is: if step 2 is omitted, SSH login will fail. ACCESS_REQUEST packets with INCORRECT password were even sent to the Radius server. Further troubleshooting showed that PAM_Radius module got a bad password from PAM. I did some research from the website and some emails dated in 2006 said that PAM_Radius can only authenticate user accounts in /etc/passwd file. Is that right? Many thanks in advance, Feng

PAM module unknown
by Robert Svensson 24 Mar '09

Hi, I can compile the FreeRADIUS PAM module without any errors. But when I try to use it I always get a module unknown error. For example: AUTH-PAM: BACKGROUND: user 'john' failed to authenticate: Module is unknown This is how I compiled the module: gcc -fPIC -c pam_radius_auth.c gcc -shared -o pam_radius_auth.so pam_radius_auth.o -lpam What did I do wrong?

Expiration vs WISPr-Session-Terminate-Time
by Santiago Balaguer García 24 Mar '09

24 Mar '09

Hi, Today I did some test with radreply.WISPr-Session-Terminate-Time and radcheck.Expiration. It is supposed both attributes do the same, but Expiration is from AAA server side, meanwhile Session-Terminate-Time is from NAS side. However, there is a difference if you want to to set a username with Session-Timeout (johndoe, Session-Timeout, :=, 3600) since the NAS rewrite the Session-Timeout according to the Date in Session-Terminate-Time. This behaviour does not happen with Expiration attribute. Do you confirm this? _________________________________________________________________ ¿Quieres ver los mejores videos de MSN?

> Why are you developing something for a server version years out of date??? Why not use current version? Read doc/bugs about how to debug this.One of the products am working with is using FR 1.1.5The same .so library is working for another FR1.1.5 which is compiled.pamtester is displaying segmentation fault soon after invoking pam_start().Thanks,Sri.

How to log failed login attempts?
by bastardinho69 24 Mar '09

24 Mar '09

Hi, i am using FreeRADIUS 2.0.5. Successfull logins into cisco routers are logged great (using Accounting), but i need to log also the failed attempts. In /var/log/radius.log radius does log the failed attempts, BUT if in clients.conf i have created client as 10.0.0.0/8 (a network, not a host), then in the log file i will see the NAS ip address 10.0.0.0/8, which is not enough. I need to see the exact NAS ip address. It would be insane to add every single router into the clients.conf file, so i assume there is a way how to solve this. I hope u guys can help me, i will appreciate it ;) Thanks.

Logging the return code from the ldap authentication to SQL.
by Augusto G. Andreollo 23 Mar '09

23 Mar '09

Hello all. I have the need to log the return code from the LDAP authentication to our database (I'm adding it to the postauth table scheme). I've already modified the database scheme (ok), the attribute map, to create a new attribute called "reason" (ok) and the insert queries (ok). All of this is working fine, including the complete authentication, all the way thru Access-Accept and Accounting. My problem now is getting the return code into the variable, according to the LDAP module results. I've made two attempts so far, and neither gave me too much success: First, with a series of IFs and ELSIFs: authenticate { Auth-Type LDAP { redundant { ldap1 ldap2 } if (rejected) { update control { reason = "rejected" } } elsif (fail) { update control { reason = "fail" } } elsif (notfound) { update control { reason = "not found" } } elsif (ok) { update control { reason = "ok" } } else { update control { reason = "ERROR" } } } } Which gives: rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful [ldap1] user user@university authenticated succesfully +++[ldap1] returns ok ++- policy redundant returns ok ++? if (rejected) ? Evaluating (rejected) -> TRUE ++? if (rejected) -> TRUE ++- entering if (rejected) {...} +++[control] returns ok ++- if (rejected) returns ok ++ ... skipping elsif for request 0: Preceding "if" was taken ++ ... skipping elsif for request 0: Preceding "if" was taken ++ ... skipping elsif for request 0: Preceding "if" was taken ++ ... skipping else for request 0: Preceding "if" was taken +- entering group post-auth {...} (and then it goes on to successfuly add the string "rejected" to the database. Again, that part is working smoothly). My second attempt was with a switch statement, as follows: authenticate { Auth-Type LDAP { redundant { ldap1 ldap2 } switch "%{control:rcode}" { case ok { update control { reason = "ok" } } case rejected { update control { reason = "rejected" } } case notfound { update control { reason = "notfound" } } case fail { update control { reason = "fail" } } case { update control { reason = "ERROR" } } } } } Which gives me the following (Again, I've skipped what I believe to be unneeded): rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful [ldap1] user user(a)university.com authenticated succesfully +++[ldap1] returns ok ++- policy redundant returns ok expand: %{control:rcode} -> ++- entering switch %{control:rcode} {...} +++- entering case {...} ++++[control] returns ok +++- case returns ok ++- switch %{control:rcode} returns ok +- entering group post-auth {...} And then goes to successfully write "ERROR" the database. (to save room, i've already tried encasing the case options in quotes, as 'rejected', 'ok', etc.. that gives me the exact same results. So does putting it on double quotes, as "ok", "rejected", etc..) So, any ideas? btw: $ radiusd -v radiusd: FreeRADIUS Version 2.1.3, for host i386-portbld-freebsd7.0, built on Jan 9 2009 at 07:02:31 -- Augusto G.
