yes you will. You will be able to use a combination of two splunk configuration files, authentication.conf and authorization.conf to configure ldap authentication for Splunk and create/map splunk roles to security groups in Active Directory. Here are two good references covering the ways Splunk can integrate with Active Directory/LDAP, all at the application level, so it won't matter what operating system you are running it on.
Hey thank you for your response. I am asking bout the service account at a linux level to install splunk with. So when I install splunk on linux I am not going to use the linux root account, i want to use a splunk account that is on an ldap server. Is this possible and/or even possible?
Since you are referring to an operating system level account and not one within the Splunk application, you will need to use a samba-client component on your Linux server such as winbind. You will install those components and configure it to participate in Active Directory. This will allow you to create an Active Directory synced account on your operating system. Then you can use that account and follow the Splunk installation procedure for installing with a no privileged account.
