hi all, never enabled/used SSO for Netsuite. Any pointers or anything to be careful about?

It's pretty foolproof, to be honest.

Admins can’t use SSO

@MGBC sorry could you add a bit more info?

It's in the documentation. https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/bridgehead_N3827426.html#SSO-Permission-Limitations

thanks both

Sorry yes as the documentation states if you have the administrator role you cannot use SSO
