Community Members I have been unable to use UPN (User Principal Name) when entering credentials for Win10 client VPN. The AD connected PCs accept UPN without issue but client VPN requires sAMAccountName. Basically, client VPN requires this format Domain\Username But any other connection to the DC can use the Username@DomainName format. Has anyone else experienced this and if so were you able to fix it? Best Regards, Stach53
