Does my Linux host need to be joined to AD in order for me to use KeyTab files for Kerberos authentication

Hello,

Can someone please help with the following

If I have an App/WEB site etc. on a standalone Linux host (Kerberos aware), e.g. no realm trusts of any kind

Then I have an Active Directory domain with my Users and I create a KeyTab file on Windows using KTPass with the relevant information, SPNs of Linux Service and AD user this information is to be associate with (to request a service ticket) 

I then take the KeyTab file and import/setup on the Linux host

Do I also need to join the Linux Host to Active Directory (using SSSD or Centrify for example) in order to the KeyTab file to work?

I would be very grateful for any help on this please

Thanks
