FORTIGATE FSSO Problems

Hi Experts,

please can you help me with the SSO agent ?
The agent is installed on each DC in my network and in sync mode.
For the IT department I use a webfilter in my FORTIGATE with SSO.

But for some users I always get messages from my FORTIGATE like this :

Message meets Alert condition

the info on "subtype=violation  pri=warning status=deny vd="root" " looks like there is attempt to login via root and using "service=443/udp proto=17 " trigger the "rule=79 policyid=79 " - maybe good to use diagnose debug flow to show traffic hitting this policy id 79...
see http://docs-legacy.fortinet.com/cb/html/index.html#page/FOS_Cookbook/Firewall/cb_fw_verifytraffic.html

there is forum talking on FSSO alert too and eventually is the version support (initially they suspect the "group filters") though but it does have some debug steps which may be useful

this is the strange part : service=443/udp

root means here VDOM:root

if you reference the guide in reading the FG log, as per "Log header", and also as you mentioned, vd=(root) is the name of the virtual domain where the action/event occurred in. The key is in the policy for cases the FG does not have any virtual domains exist (or configured), this field always contains root.

For the "Log  Body", the service=(https) refers the IP network service that applies to the session or packet. The services displayed correspond to the services configured in the firewall policy. Will have to check the policy per se as it is configured to detect this as well.

Indeed it is strange as typically it should be TCP 443 instead of UDP 443 (which is why it did not state as "https"). I am suspecting some service is transacting using 443 port but it is not adhering to the perceived HTTPS services..
