Can´t get Web authentication on HP Procurve 6200yl working

Hi,

I just got some new HP 6200yl (firmware 13.25) swtiches. I followed the steps (at least I thought so) to setup Web Authentication with RADIUS-Server an PEAP+MS-CHAPv2.

My problem is, that when I connect the test computer to the appropriate port, it doesn´t get the "public" IP address from the switch and therefore I can´t login on the web login page.

show port-security... says that that web authentication is enabled, but it simply doesn´t work.

I am just asking myself whether I forgot something to configure?

Re: Can´t get Web authentication on HP Procurve 6200yl working

hmmm...a 'show run' would help...

also, what "brand" of radius server are you running?

----------

here are minimal commands needed on the switch to make 802.1X auth work:
--
radius-server host 10.1.1.202

aaa authentication port-access eap-radius

aaa port-access web-based 13
aaa port-access authenticator active
--
the last command is quite often overlooked and is required to make 802.1X auth work...and if its not there, the result is basically what you are seeing...

Hi,

it´s a Windows 2003 Server with IAS/RADIUS on.
This is already working for weeks with Wireless LAN and 802.1X.

I´ll reset the switch and try it again with your instructions. Let´s see whether it will work then


thanks in advance

Re: Can´t get Web authentication on HP Procurve 6200yl working

you'll also need to have a remote access policy in IAS linked to the web-auth group for web-auth users if you don't already have it configured...

also2, the web-auth userid needs to have its password set for reverse encryption, so if you've already set the pw, you need to set the option for reverse encryption and then reset the password so it now stores it in reverse encrypted form...

finally, if you look at the event viewer/system/IAS log entries, this provides the best information for 802.1X operations troubleshooting...

I'm pretty sure that now MS-CHAPv2 is supported, you don't need to enable reversible encryption. It was only for CHAP/MD5 if my memory serves me correctly.

Re: Can´t get Web authentication on HP Procurve 6200yl working

i concur with matt's comments...

i was operating in the "old days mode", reversible encryption is not needed in K.13.xx code for web-auth/mac-auth...

it is needed for switch management authentication and for PEAP-MD5...


good catch matt :-)

Hi,

tried it again, but it doesn´t work. I don´t get an IP via the inbuilt dhcp service of the switch.

hmmm, as i see the config, it all looks good...

dumb question from me, the device connecting to one of the web-auth ports is set to dhcp an address - yes?

also, when you do a 'sh port-a web' the web-auth ports should be in closed state...


not sure what the deal is now...

Hi,

of course DHCP is enabled...
Has anyone another idea, what the problem could be?
