I have recently implemented Zammad and successfully set up SAML authentication to Google Suite.
I’d be willing to help add the instructions to the Documentation resource in github, however I wasn’t sure if it would be accepted or in which area would be best for contribution.
I have attached a word document rough draft (I apologize if external links aren’t allowed) if anyone would like to try to implement.
