User is experiencing an O365 SSO issue when attempting to log in via Citrix FAS
I recently set up Citrix FAS to improve the security of my OnPrem Citrix environment. When testing the login process with Citrix FAS, the user is redirected to Azure to sign in with their credentials, and the login is successful. However, I’ve noticed that SSO for O365 Apps isn’t working in the Citrix session.
when i using CMD and doing dsregcmd /status i get
