MacOS platform SSO deployment issues

Hello,

 

We tried to deploy MacOS platform SSO but the devices are having problems with their authentication. The devices are connected through company portal but keep asking for logins and authentication, especially on reboot. Some users are prompted to sign-in to their entra account several times per hour.

 

To Deploy it we used the configuration setting template:

Authentication > Extensible Single Sign On (SSO)

 

Settings:

 

Extension Identifier: com.microsoft.CompanyPortalMac.ssoextension

 

Authentication Method: Password

 

Token To User Mapping:

 

Account Name: preferred_username

 

Full Name: name

 

Use Shared Device Keys: Disabled

 

Team Identifier: UBXXXXXX

 

Type: Redirect

 

Has anyone here experienced similar issues or found a fix for these constant re-authentication prompts? Thanks!
