Kerberos Information Not Showing In NAC

Anonymous — Wed, 22 May 2019 21:21:44 GMT

Hi,

Have this working on another site, but trying to replicate it I cannot seem to get it working or find any step I'm missing?

The switch firmware is 22.4.1.4-patch1-2
XMC / Control is 8.2.4.55

The configuration on the switch is as follows:

code:

create xml-notification target nac-target_10.1.0.85 url https://10.1.0.85:8443/axis/services/event vr VR-Default
configure xml-notification target nac-target_10.1.0.85 user admin

Extreme@pp

configure xml-notification target nac-target_10.1.0.85 from 10.1.10.38
configure xml-notification target nac-target_10.1.0.85 add idMgr
enable xml-notification "nac-target_10.1.0.85"

enable ip-security dhcp-snooping vlan Staff ports all violation-action none
enable ip-security dhcp-snooping vlan Students ports all violation-action none

configure trusted-ports 51 trust-for dhcp-server

configure identity-management kerberos snooping add server 10.1.10.71
configure identity-management kerberos snooping add server 10.1.10.72
configure identity-management kerberos snooping add server 10.1.10.70
configure identity-management kerberos snooping add server 10.1.0.74
configure identity-management kerberos snooping add server 10.1.0.75
configure identity-management kerberos snooping add server 10.1.0.73

When you look at XML notification it looks fine:

code:

# show xml-notification statistics 

Target Name             : nac-target_10.1.0.85
Server URL              : https://10.1.0.85:8443/axis/services/event
Server Queue Size       : 100       
Enabled                 : yes       
Connection Status       : connected 
Events Received         : 16        
Connection Failures     : 0         
Events Sent Success     : 16        
Events Sent Failed      : 0         
Events Dropped          : 0

Idmgr also looks fine. I've replaced sensitive information with x's:

code:

# show identity-management entries 
ID Name/          Flags  Port        MAC/          VLAN            Role         
Domain Name                          IP
--------------------------------------------------------------------------------
xxxxxxxx        --k-  43     a4:4c:c8:a9:56:be  business(1)     authenticated
BUSINESS.xxxx.AC.UK              10.1.24.171(1)       
xxxxxxxx        --k-  13     a4:4c:c8:dd:fa:6c  business(1)     authenticated
BUSINESS.xxxx.AC.UK              10.1.24.82(1)        
xxxxxxxx             --k-  33     48:ba:4e:61:a4:23  business(1)     authenticated
BUSINESS.xxxx.AC.UK              10.1.27.80(1)        
xxxxxxxx            --k-  21     18:66:da:2b:92:cc  academic(1)     authenticated
BUSINESS.xxxx.AC.UK              10.0.25.151(1)       
xxxxxxxx          --k-  5      18:db:f2:44:b4:4e  business(1)     authenticated
BUSINESS.xxxx.AC.UK              10.1.24.170(1)

When I look up any of these end-system in XMC I should see the authentication as 'Kerberos' and the 'User Name' filled in with the username show in idmgr.

Currently I have MAC auth enabled on the ports only.

XMC Connect Extreme Control Module has the kerberos function enabled. When I enable debug mode I believe the below is showing me the process is working, but no mention of the devices and type of authentication:

code:

2019-05-22 10:23:30,295 DEBUG [com.enterasys.fusion.modules.NetSightHandler] ES Group Storage: Retrieved data for endsystem group [Web Authenticated Users]: com.enterasys.fusion.common.EndSystemGroup@2cc952ee[approvalRequired=false,description=End-Systems that have authenticated through the NAC web interface and been granted permission to access the network,lastUpdate=May 22, 2019 10:23:30 AM,name=Web Authenticated

I'm seeing all the end-system information like IP, Hostname, Device type & family, but not the user name.

Just wondering if anyone has any ideas.

Thanks in advance

Well perhaps it was just because I wasn't patient enough, but had to leave it at least an hour (I believe) and it started working!

There is probably a very logical explanation for that, but least I know the configuration works 

Hi Martin.

can be related to reauthentication? Some properties are updated only in end-system history and not in the end-system table. Not sure if it is the case with username.
