SDP+ login

SDP+ login

Randomly, SDP+ logins won't work. We are using NTLM SSO and for the most part it works. (planning on switching to SAML SSO this week). Randomly it will not work though, and the user is required to enter their credentials. Sometimes it works and sometimes it doesn't even though the user has entered the correct credentials. When it doesn't work, the user has to reboot their computer, and then they are able to login. Anyone else experiencing this issue? We are on the latest build and use Chrome ver. 94
