How has the SQL Server Always On Availability Group (AG) synchronized the Security Objects Across Replicas (2012 - 2025)? -Part IV

4. SQL Server 2017 - Improved Linked Server Security

Enhancements:
Linked server logins now support better security delegation.
Support for Kerberos authentication across replicas.

Steps:
Use Kerberos Authentication for Linked Servers

EXEC sp_addlinkedserver 'SecondaryReplica';
EXEC sp_addlinkedsrvlogin 'SecondaryReplica', 'false', NULL, 'SQLUser', 'Password';

Advantages:
Stronger authentication methods reduce security vulnerabilities.
Improves login synchronization for linked servers.

Limitations:
No native automatic login replication for SQL logins.
