How to Bypass the Single Sign On (SSO) Process
03/26/2020 201 16151
When SSO fails to authenticate a device, which is very common for servers and other network appliances that do not normally require authentication to the firewall, a device is put on a time out delay. All connections from that device are held/dropped until either that time out has passed or the device successfully authenticates. This time out is configurable, and by default is 1 minute in the current firmware. Furthermore, once a device has been timed out the sonicwall will reattempt the authentication again 1 minute later causing a repetitive failure cycle where web browsing can be very slow or function in quick bursts.
On the SSO configuration page, there is an option on the Enforcement Tab for Exclusions. Any device which is not going to respond to the SSO agent, such as Server, Routers, Printers, Voip Phones, ect. Should be identified and excluded from the SSO process. This will reduce the workload on your sonicwall and improve performance for the devices in question.
Step 1: Create an Address Object Group example: "SSO Bypass Group"
Step 2: Create an Address Object for the device you with to bypass, and make it a member of the bypass group from step 1.

Step 3: Under Users | Settings click Configure SSO... option
Step 4: On the Enforcement Tab, click Add select the group you created in step 1.
Step 5: Save at the bottom to finish the procedure, by clicking the OK button..
