Is my config

auth_method:
  - external
extauth_program: "/xmpp/auth" 
extauth_cache: 0
extauth_instances: 10
auth_use_cache: false

[licaon-kter]

that /xmpp/auth is a script? in which language?

[licaon-kter]

which guide you followed when you wrote that?

eg. I've seen https://www.ejabberd.im/files/doc/dev.html#htoc9 but not sure how current it is

I tried to translate Python into a Golang version and compile it into an executable file， convenient for it to run directly on my Centos 7.9

Yes but your script is called with certain params and must answer with certain codes
