Situation

The registration process of a Client against a SMT server is an interactive procedure, but in larger environments login into each Client is not longer an option, so a non-interactive registration is needed.

Resolution

The SMT Client registration script includes an option to pass it the certificate fingerprint of the SMT Server in order to avoid interaction during registration, so the first step is to get the fingerprint by login as root into the SMT server and run the following command :
# openssl x509 -noout -in /srv/www/htdocs/smt.crt -fingerprint -sha1

The SHA1 fingerprint output should look similar to this :
 DE:B8:F6:7F:13:30:FB:A5:D1:63:3F:9F:93:85:E1:17:B6:0A:60:17

The next step is to login as root into the Client you want to register and get the registration script from the SMT server with:
# wget http://YOUR-SMT-FQDN-HERE/repo/tools/clientSetup4SMT.sh

Set the proper permissions to be able to execute the script:
# chmod 755 clientSetup4SMT.sh

And finally, run the registration process like this:
# ./clientSetup4SMT.sh --host <YOUR-SMT-FQDN-HERE> --fingerprint <YOUR-SMT-CERTIFICATE-FINGERPRINT-STRING-HERE> --yes

And that is it, registration will be performed without any user interaction.

Cause

After a Subscription change, Organization change or as a consequence of an issue on the SMT server side, all Clients must be re-registered.

Additional Information

This procedure could be adapted as an automated method to be deployed remotely on many SMT Clients via SSH or any job/batch scheduling tools.
