(How) can I get two client certificates in one APM session?
I have a customer with iPads that need to authenticate to APM with a user certificate. This has been working fine, but there is also now need to read a field from a per-device certificate on each iPad and make use of this within the access policy. The two certificates are issued by different authorities. Maybe I am wrong, but it seems impossible to change the client SSL profile by renegotiating SSL during the session, so as to let me check the user cert and then the device cert. Does anyone know of a way? TMOS V16.1
client and server ssl profiles
I am new to f5 asm, in our environment we have set up a website behind WAF in transparent mode, We have installed a wildcard certificate on real web server and replicated it on waf using client and server ssl profiles. However, when we attach this created custom profiles to virtual server site doesn't work. Interestingly, when we replace it with client/server-insecure-compatible ssl profiles site works properly. Furthermore, site works normally when we bypass waf. What steps should we take to address this issue?
Create client-ssl profile with tmsh error

I try: create ltm profile client-ssl /Part_123/clientssl_123.xyz.com_1 { app-service none cert /Part_123/clientssl_123.xyz.com_1.crt cert-key-chain add { clientssl_123.xyz.com_1 { cert /Part_123/clientssl_123.xyz.com_1.crt key /Part_123/clientssl_123.xyz.com_1.key chain /Common/Int-CA.crt }} chain /Common/Int-CA.crt key /Part_123/clientssl_123.xyz.com_1.key defaults-from /Common/clientssl_onlyECDHE server-name 123.xyz.com } All partitions and cert and so one exist.

Custom cihper suite for ClientSSL Profile
Hello Folks, I want to use a custom set of ciphers in my ClientSSL Profile. I have gone through the document of F5, how can disallow ciphers by putting ! However I have a requirement that I need to use only 2 cipher suites such as AES128-SHA256 & AES256-SHA256 and rest should be deny. How can I deny remaining cipher suites by allowing only the required one? Any help is appreciated. Cheers! Darshan
Client SSL profiles using SNI not able to use the subject alternative name
We have a clientssl profile using a *.domain.com wildcard SSL certificate. This profile is set as the default for SNI. We also have specific clientssl profiles using the application specific SSL certificate. The application specific certs have their subject as www.application.com with the subject alternative name with application.com. There may also be several other SAN listed depending on the web app. In testing everything works great when accessing the site via https://www.application.com. However when using https://application.com we receive a cert error and the *.domain.com wildcard SSL certificate is used. This is the same for any domain listed as a SAN. My main question is can SNI use subject alternative names? My testing indicates no, but I wanted to put this out to the group. Here is my sanitized config: ltm profile client-ssl domain.com_wildcard { app-service none cert domain.com_wildcard.crt chain ComodoCA.crt defaults-from clientssl key domain.com_wildcard.key sni-default true } ltm profile client-ssl prod-www_application_com { app-service none cert prod-www_application_com.crt chain prod-www_application_com.intermediate.ca.crt key prod-www_application_com.key } ltm virtual vs-x.x.x.x_443 { destination x.x.x.x:https ip-protocol tcp mask 255.255.255.255 pool site-x.x.x.x_443 profiles { http-x-forward { } domain.com_wildcard { context clientside } prod-www_application_com { context clientside } serverssl-insecure-compatible { context serverside } tcp { } websecurity { } } source 0.0.0.0/0 source-address-translation { pool snat_pool type snat } vs-index 2539 }Support dynamic CRL check for clientSSL profile (BIG-IP 15.1)
Hi, Did anyone tested (dynamic) CRL validator object for client SSL profile? (BIG-IP v15.1): It should work in v 15.1 (fixed bug 743758 - https://cdn.f5.com/product/bugtracker/ID743758.html ) I'm getting following errors for all client certificates: err tmm1[21207]: 01a40008:3: Unable to build certificate trust chain for profile /clientssl_profile tmm1[21207]: 01260009:4: clientIP:62042 -> VIP:443: Connection error: ssl_hs_do_crl_validation:6014: alert(46) unknown certificate error With CRL File it works ok, but file does not automatically fetch, check, and cache CRL files… Kr, EPXTCL error: _cgc_pick_clientside
Hi, in an ASM-LTM (Perimeter) Setup I see frquently the following logs: ***err: tmm3[19962]: 01220001:3: TCL error: _cgc_pick_clientside - unknown cgc sni: f5-bei1.xxxx.xx (line 49) invoked from within "CGC::sni $tls_servername"*** Any idea what this TCL error causes? The clientssl is quite Basic: one certificate chain, no Server Name set. Thanks, Rolf
Unique identification of client in SSL Mutual auth
Hi, I have been using SSL Mutual Authentication via LTM. IN previous implementation A single client certificate was used to multiple clients, now I need to identify clinet uniquely by client Certificate via mutual auth. and have to make sure that single client certificate can not be reused by other client. What are the possibilities to achieve this via LTM or by any other BigIP module and how.?
