To force kebros login, disable local passwords and require valid tickets on every host. You must also block fallback methods like NTLM or plain text keys. Teams often set up central key servers to manage these rules across their network. Still, broad domain roles often grant logged-in users too much power across many servers. Once a user gets a ticket, they can often run any command they want.
How to force kebros login in your network
A Kerberos setup uses a central key server to check user identities and issue tickets. First, you join every target server and database to the same central realm. Next, you create a service record for each host in the central directory. Each host gets a secret key file that matches its record in the directory.
When a user wants to log in, they ask the key server for a ticket. The user proves who they are, and the key server sends back a session ticket. The user client then sends this ticket to the target server to start a session. To force this flow, admins turn off local password checks in the host settings.
You also have to turn off older login protocols across the whole domain. Many systems fall back to weaker password hashes when a ticket check fails. If you leave fallback options on, attackers can bypass the ticket check. Turning off these fallbacks ensures every person and app uses a valid ticket.
Where a ticket check works and where it falls short
Enforcing ticket logins stops plain text passwords from moving across your network wires. It also lets your team cut off user access from one central place. When someone leaves the team, you disable their central account and revoke their tickets. You do not need to wipe local password files on fifty different hosts.
Still, a ticket check only decides who can open the door at the start. It does not check what commands or queries the user runs during the session. Most teams map central directory groups to broad host roles like admin or read-write. Anyone in that group gets full control once the host accepts their ticket.

Central key servers also cannot see inside database queries or shell sessions. The key server logs show that a user got a ticket for a database host. Those logs never show which tables the user read or which rows they deleted. If a query pulls emails, phone numbers, card numbers, or national IDs, Kerberos will not rewrite matched fields in results.
Why clock sync and service records matter
Ticket logins rely on strict time checks to stop attackers from reusing old tickets. Every host in the realm must keep its system clock within a small window. If a server clock drifts too far, the host rejects valid user tickets right away. Teams must run network time services on all hosts to prevent sudden login lockouts.
Service records also need careful upkeep as hosts change names or move across networks. A client checks the exact host name against the service record before sending a ticket. If a team connects through a load balancer with a different name, the check fails. Admins must match DNS records and service names so tickets work every time.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
Why do users still get a password prompt when tickets are required?
This usually happens when the client lacks a valid ticket or uses an IP address. Kerberos needs the exact domain name to match the host service record.
What happens if the central key server goes offline?
Users with active service tickets can keep working until those current tickets expire. Still, no one can request new tickets or start new sessions until a backup responds.
Does forcing ticket logins protect sensitive data inside a database?
No, ticket checks only verify identity at the start of the database session. Once inside, the user can still read any table their database role allows.
