SSB – Connection handshake failed
SSB – Connection handshake failed
The following shows you some kinds of SSB exception when enabling Transport Security and Dialog Security in the cross-server Service Broker conversation.
1. Connection handshake failed. The certificate used by the peer is invalid due to the following reason: Certificate not found.
HINT: Usually this error is related to the EndPoint authentication, so the problem is from the certificates in MASTER DBs in two SQL SERVER instances. Please make sure that the right certificates are deployed and referenced. Look into master.sys.certificates in two respectively SQL SERVERS and validate the certificate cert_serial_number or thumbprint matches between two instances.
2. Connection handshake failed. The certificate used by the peer is invalid due to the following reason: The database principal has no mapping to a server principal..
HINT: You are using certificates for adjacent transport security. The certificate used by the peer belongs to a user in master DB who is not mapped to a login. This could happen for the following cases:
(1) You created a user in master without login.
(2) You created a user in master with login, but later dropped that login, thus orphaning that user.
The fix would be to create a SQL login, then create a user in master for this login and alter authorization of the peer’s certificate to be owned by this user. Next grant connection permission on the service broker endpoint to the newly created login.
You can refer to the following SQL SCRIPT for help.
-- Create a new login & user in the MASTER system database
Create Login Demo_Login
With password=’YOURPASSWORD’
GO
Create User Demo_User
For Login Demo_Login
GO
-- Give authorization permissions
Create Certificate YOURCERTIFICATENAME
Authorization Demo_User
From File=’THE PEERS CERTIFICATE FILE’
GO
-- Grant CONNECT permissions to the associated endpoint
Grant Connect on EndPoint::DB_ENDPOINT to Demo_Login
GO
