I have a number of VMs linked to Azure AD Domain services with LDAP and can authenticate and login correctly, however, those users cannot access sudo. I tried to add a user account to the sudoers file in the format used to login <firstname>.<lastname>@domainname.com, however it didn't work.
I found a Microsoft article about AD authentication on Linux and it recommended a series of steps including installing the Azure extension named AADLoginForLinux. After installing the extension, the account which was able to login previously was no longer able to login anymore. I had followed the steps to add the RBAC role Virtual Machine Administrator Loginfor that account.
Any guidance or suggestions would be welcome.
