GlobalProtect portal user authentication failed

For globalprotect I have a radius server profile with two servers in it.  I have noticed that all authentication goes to the first server in the list all the time.  And that works.  However, in testing, I have shut off the first server and the firewall never tries to send authentcation to the second server.  If I use the "test authentication" command on the firewall CLI, it does fail over to the second server and authentication succeeds.  If I go back to the globalprotect client and try again, the firewall only tries the first server and authentication fails.  I have verified this with packet captures on the actual radius servers.

 

This seems to be incorrect behavior.  Is it possible that there is a known bug about this?  I'm using the same authentication profile in the globalprotect portal configuration as I am on the test CLI command.

@howardtopher,

To know if you are hitting a known bug, we would need to know your PAN-OS version and GP agent version ;-)

 

I recall this issue a while ago this issue was brought up and the fix was modifying the retries and timout values lower; something with that agent version was timing out the authentication on the agent side of things before getting a response. That particular issue if I recall correctly had much higher values in both fields however.

Our PAN-OS is 8.0.10.  Maintenance night is next Friday, we'll jump to 8.0.13 at that point unless 8.0.14 gets released before then.

 

Globalprotect is 4.1.5.

 

I tried setting the timeout to 1 second and retries to 1 in the server profile, but that didn't make a difference.  The globalprotect client says "connecting..." for a good 30 seconds before giving up (I haven't timed it, but it's feels long).  The CLI fails over to the second server in the 1 second timeout that's configured.

@howardtopher,

I don't think it's your PAN-OS version, nothing in the release notes point towards a fix for anything to do with RADIUS between those versions. You could be running into GPC-7215 if you are using SSO.

yes @BPry i remember that post too!

 

unfortunately the poster never updated so still hanging...

 

the main pont to remember is that the max retries is 5.

 

so if you have 2 servers then only set retries to 3. (or less)

 

I have just tested 4.15, i have radius server profile with 2 laptops running wireshark.

the timeout is 3 and retries is 3.

 

i see the first laptop get 3 radius requests with about a 3 to 3.5 second interval.

 

i then see laptop 2 get 2 radius requests (total 5) with similar intervals.

 

as soon as the second one times out my GP client re prompts for username and password so all looking OK.

 

i cannot think why you would have such an issue...   i have tested this on V7.1x and 8.08
