Centralized authentication with SSH

[olivier.dumonexodata.fr]

Hello everyone.

I'm looking for docs, tutorials or other requirements to setup a centralized SSH authentication on pfSense.
I found some docs to perform SSH authentication with AD directory for Linux or FreeBSD.
But each time, I have not managed to run authentication.

If anyone knows how to set up a centralized authentication for LDAP, Kerberos, RADIUS (or else!).

Thanks in advance !

Regards  :)
