KB 775235 - Kerberos Authentication – Overview
What is Kerberos?
Kerberos is a secure authentication method used in our Active Directory (AD) environment (mbuzztech.com).
It allows users to:
- Access multiple systems without re-entering passwords (Single Sign-On – SSO)
- Log in once
Where We Use It
Kerberos is used for:
- Windows domain login
- Access to shared folders
- Internal applications
- Network resources (printers, servers, etc.)
How It Works
- User Login
User logs in using domain credentials (mbuzztech.com) TGT Request (Ticket Granting Ticket)
System contacts the Domain Controller
A TGT (Ticket Granting Ticket) is issued after successful authentication
TGS Request (Service Ticket)
When accessing a service (file server, app, etc.), system uses the TGT
Requests a TGS (Service Ticket) for that specific service
- Access Resource
Service ticket is presented to the target system
Access is granted without asking for password again
Key Components
- User Device – Employee laptop/desktop
- Active Directory (Domain Controller) – Authentication server for mbuzztech.com
- TGT (Ticket Granting Ticket) – Initial authentication ticket
- TGS (Service Ticket) – Ticket used to access specific services
Why We Use Kerberos
- Single Sign-On (SSO)
- Secure authentication (no repeated password transmission)
- Centralized control via Active Directory
- Seamless access to internal systems
