Hello, First post ever on devcentral so I ask that you take it easy on me haha. Anyways, recently stood up some new R-series F5s and F5OS is a new world for me. Currently running iSeries appliances. Going through some of the basic configurations and I've made my way to authentication. I've added radius as one of my accepted authentication options and created my server group with the clearpass server attached in that group. Selected radius, put in the correct IP, radius secret, etc. Per the documentation it looks good. Going into clearpass for those familiar - Created my new F5 device, put in the shared secret, added new device to my existing F5 device group. Essentially all I've ever had to do when working with other vendors. Attempting logins with my user account I get hit with "Permission Denied" at the login screen. This is where I am lost. I check clearpass, my access tracker says I successfully authenticated. Clearpass shows no obvious issues. I log back into F5OS with my local admin and I check the login activity. Shows my user account and a big ole "Success" for the login attempt. I apologize for the word salad. I was trying to put my process out there including that both F5OS and Clearpass seem happy with my attempt but the F5OS login page says denied. Anyone have any R-series appliances using clearpass for radius and authentication? I'm curious what I'm missing.318Views1like2CommentsR-Series after upgrading to 1.8 - RADIUS Auth stopped working
Radius user authentication was working just fine while running v1.40. After upgrading to 1.80 any attempt is "Failed authentication." Running tcpdump does not show any traffic going to the RADIUS server and the RADIUS server has not entry of the failures in it's log. I have deleted and recreated the radius server group - that did not help. I have deleted and recreated users - that did not help. Any guidance for what to try next is appreciated.

We currently have a Radius authentication in our access policy on F5 APM. Sometimes the user may mis-input the token received from SMS and we would like the Radius authentication page to ask the user to input again instead of redirecting back to logon page on first mis-input, in other words to have a second attempt for token input with the same token from SMS. Can we achieve this function in F5 APM? Thanks a lot.196Views0likes7CommentsAPM Domain/Username for RADUIS Auth
Hello community, could you help me with the following?. I've a simple per session AD Authentication policy -> working fine 2nd. I've a per-request-policy for specific paths which are secured with a 2FA Radius auth -> working also fine For user simplicity I would take over the username (domain\username) from per session AD Logon Page to per-request Logon Page. This only works in part :-/ At the moment I can pre-fill the username via session variable "session.logon.last.logonname" in the Logon Page. Username in Logon Page set to "Ready Only" After generating an OTP the APM log is showing the following error: "RADIUS Agent: Failed to read Username Source session variable:" Obviously, the variable is empty, despite pre-filling. I experimented a little with Variable Assign (implemented after Logon Page) but nothing changed. -> "RADIUS Agent: Failed to read Username Source session variable:" session.logon.last.username = expr { "[mcget {session.logon.last.domain}]\\[mcget {session.logon.last.username}]" } or session.logon.last.logonname = expr { "[mcget {session.logon.last.domain}]\\[mcget {session.logon.last.username}]" } Everything is working fine with a manual input of the domain\username in the Logo Page. Does someone have an idea to solve the issue/problem? Thanks a lot.221Views0likes2CommentsFreeradius auth for LTM V11.5.1
Guys am running out of inspiration here and hoping you may be able to help. I have set up a FreeRadius server which is successfully authenticating Linux systems and Cisco devices. I have added the config for F5 to the radius server and verified it's triggering correctly for my test user. e.g. (radiusd log extract) Mon Feb 22 14:39:35 2016 : Debug: rlm_perl: Added pair Auth-Type = PAP Mon Feb 22 14:39:35 2016 : Info: ++[perl] = ok Mon Feb 22 14:39:35 2016 : Info: +} group post-auth = ok Sending Access-Accept of id 161 to 192.168.1.90 port 27260 Cisco-AVPair = "shell:priv-lvl=15" F5-LTM-User-Shell = "tmsh" F5-LTM-User-Info-1 = "F5-admin" F5-LTM-User-Role = Administrator F5-LTM-User-Partition = "Common" Mon Feb 22 14:39:35 2016 : Info: Finished request 25. I've then followed the recipe at https://support.f5.com/kb/en-us/solutions/public/14000/300/sol14324.html and believe I have things set right. tmsh sows this when list the auth section: auth radius system-auth { servers { system_auth_name1 } } auth radius-server system_auth_name1 { secret $M$q5$0UFrYg9zh5kLp7xkZOb2vZpgAPggyDPoWmjeIgF5F1I= server 192.168.1.56 } auth remote-role { role-info { F5-admin { attribute F5-LTM-User-Info-1=F5-admin console %F5-LTM-User-Shell line-order 1001 role %F5-LTM-User-Role user-partition %F5-LTM-User-Partition } } } Trying to log in as my test user sadly yields no good outcome, in spite of the the log from the radius server showing it sending an Access-Accept packet with the relevant F5 attributes included. So I guess my question is if there is log file I've been unable to find on the LTM itself which might let me know what I'm doing wrong. This or any other thoughts would be greatly appreciated.

Hi Everyone, Am wating to implement radius auth of our BIG-IP administrators (GUI and SSH), radius is a supported auth method so we would like to use the Microsoft NPS services. Has anyone successfully implemented GUI / SSH authentication of BIG-IP Administrators via radius to Microsoft NPS? Would be great to hear of your learnings and any advice you can provide. TIA (currently running v16.1.3.1)1.1KViews0likes3CommentsRadius Authentication role not working
Hi Guys, We setup authentication setup using this article: https://support.f5.com/csp/article/K14324#3 But when we logged in using the accounts on the radius, f5 sets the user as admin account even the account should be read only. Are we missing some configurat2.4KViews0likes13CommentsBIG-IP APM: RADIUS and SSO mapping broken
Hi All I think that using a combination of RADIUS authentication (with one-time token) and SSO credential mapping within APM is broken. Credentials entered on the logon page are stored in the username & password session variables. If you do a RADIUS authentication with one-time token, the password variable will be overwritten with the token. So an SSO credential mapping after the RADIUS authentication will get a wrong password. You can prevent this with either putting the SSO credential mapping before the RADIUS block, or "caching" the initial password in a separate variable with variable assign before ( password2 = password ) and after ( password = password2 ) the RADIUS block. However, this fix will not work if the user enters the wrong password initially. The RADIUS block will reload the login page and show you the "wrong credential" warning as often as you define, but the SSO credential mapping or variable assign defined BEFORE the RADIUS authentication won't be updated with the correct password. I know that I could set the "max. attempts allowed" to 1 and have a completely new APM session after every wrong credential or I could build a loop and lose the "wrong credential" message, but those 2 options are not that pretty in my opinion. I'm just wondering if someone has a nice solution to this problem. Cheers PatrickSolved1.8KViews1like4CommentsUse debug on health monitor to retrieve lost radius secret
Hi Is it possible to use debug function on health monitors to retreive the radius secret? Found this old blogpost http://socpuppet.blogspot.com/2016/11/how-to-recover-lost-big-ip-f5-secret.html and followed the steps 1) Created a health monitor with a random username and password plus a random secret. Enabled debug 2) Edit the health monitor and entered the hashed secret from the radius setup 3) Added the health monitor to a pool and attached the pool to a new virtual server used to test 4) Check in /var/log but no debug log is created Is something missing or is it not possible to do this anymore?

Simple configuration on the F5 LTM with a UDP Virtual Server listening on all ports. For one particular client, VS is returning ICMP Destination Unreachable (port unreachable) to the client. The request came on UDP 1812. Any help in understanding what could be wrong?514Views0likes1Comment
