Creating service account in AD - active-directory

I am creating a Service account for a domain in the AD. The user is created under Managed Service Accounts. But from any server, when the user is used to start a service, I get a logon failure.
What is the rigt procedure to create a Service user on AD with only logon as a service right?
What groups should the user belong to, to have logon as a service right?

Any AD user account can be a service account. It's how it's used that makes it a service account.
The "Log on as a service" privilege is a Group Policy setting that must be granted on each computer where it is needed. You can either do this in a Group Policy on the domain, or on the computer itself by running "gpedit.msc". You'll find "Log on as a service" under:
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment

Users from on-prem AD aren't synced to Azure AD as Guest

I have a setup where I have installed the Azure AD on-prem cloud provisioning agent on a Domain joined server. The setup was successful. I followed the documentation here:
https://learn.microsoft.com/en-us/azure/active-directory/cloud-provisioning/how-to-prerequisites
After configuring the agent in Azure AD, Users can only be synced as Member.
Is there a way to sync users as Guest using the provisioning agent?
Also, is there a Microsoft Graph API to validate the agent and do the configuration?
On-prem AD isn't synced to Azure AD as Guest and those synced users cannot be a Guest user and it's as per design.
You can invite guest users to the directory, to a group, or to an application. After you invite a user through any of these methods, the invited user's account is added to Azure Active Directory (Azure AD), with a user type of Guest. The guest user must then redeem their invitation to access resources. Any user sync via AD connect will not be a guest user.

What does "grant admin consent" button do in azure Azure Active Directory application?

We have configured an azure active directory application so that the users to our website can log in via their Microsoft accounts. The problem is that if we do not grant admin access then the Sign in to the application fails with the error code AADSTS650056:
Misconfigured application. This could be due to one of the following: The client has not listed any permissions for 'AAD Graph' in the requested permissions in the client's application registration.
We are skeptical to click on "Grant admin consent" fearing that it may expose any vulnerability. Is this the right way to proceed? If not what are the alternatives so that this kind of consent is bypassed?
Each application registers permissions it requires. Some permissions can be granted by users, some other only by the administrator.
Let's suppose you have only permissions that can be consented by users. The first time they use the application, they'll be prompted (each user) to consent those permissions to the application.
If in the same scenario you click on grant admin consent, it is the equivalent of accepting it for all users on the tenant.
Now let's suppose the application registers permissions that require admin consent, you have no choice but to click that button if you want the application to work and be able to request tokens.
These permissions that require admin consent are permissions that either allow access to more or sensitive data in the organization.

RDP Access for AD Service Account?

We're trying to lock down our service accounts as much as possible.
Does an Active Directory Service Account need Remote Desktop access?
What's the minimum permissions an AD Service Account would require?
The minimum permissions an AD service account needs are the minimum permissions to do the task that you've created the service account to perform.
If you created the service account so it can RDP into another machine and do something, then yes, it needs RDP access.
If you are not using it to RDP to another machine, then no, it doesn't need RDP access.
It's up to you to decide.

Azure Active Directory access denied

I am new to Azure and want to use "login with Microsoft" in one of my web apps.
For this I have created a new account on portal.azure.com.
When going to Azure Active Directory tab in account I am getting this error-
Access denied
You do not have access
Looks like you don't have access to this content. To get access, please contact the owner.
I found a similar question where they advice to login with Global Administrator permission for Azure AD.
Azure Active Directory - Access Denied in New Portal
But I don't know what is that Global Administrator permission for Azure AD is? I just signed up with my email and that's the one account all I have.
You need to create a "tenant" to do something with AD. Check the documentation
In short, login into azure portal, go here https://portal.azure.com/#create/Microsoft.AzureActiveDirectory and create new directory.
Global Administrator / Company Administrator: Users with this role have access to all administrative features in Azure Active Directory, as well as services that federate to Azure Active Directory like Exchange Online, SharePoint Online, and Skype for Business Online. The person who signs up for the Azure Active Directory tenant becomes a global administrator. Only global administrators can assign other administrator roles. There can be more than one global administrator at your company. Global admins can reset the password for any user and all other administrators.
Note: n Microsoft Graph API, Azure AD Graph API, and Azure AD PowerShell, this role is identified as "Company Administrator". It is "Global Administrator" in the Azure portal.
Details about the global administrator role
Assign a user to administrator roles in Azure Active Directory
You need to assign the co-admin as global administrator with using account admin user. Log in to new Azure Portal by using the account with Global Administrator permission for Azure AD. Navigate to the Azure Active Directory extension, from the Users and Groups tab, search for the external account, and change the Directory Role to Global Administrator.

Azure AD permissions for app only token

I need to create a service which gets messages from specific office 365 mail box user100#atenant.onmicrosoft.com/.
My understanding is that in this case I need to specify required permissions in application registration for my app in the Azure management portal for Microsoft Azure Active Directory.
Is it possible to provide mail.read permission to the particular account instead of mail.read.all?
No , you need to write your own code in app to restrict access to particular account , and you should grant mail.read.all application permission which allows the app to read mail in all mailboxes without a signed-in user.
And if you only wants to read emails from particular account in a service , you could try delegate permission with mail.read and use the Resource Owner Password Credentials Grant.
