Hmm, there is a PAM authentification plugin in mysqlnd[1] for
years – I wonder if it's just broken.

Thank kstan! I got your gist working in a docker container after a few modifications. I would still
prefer mysqlnd supporting PAM auth though.

I have also been able to reproduce this using mysqlnd with PDO and mysqli on php versions 7.0, 7.1,
7.2. I have not yet got around to recompiling PHP to use libmysqlclient to see if that also fails.

Yes, wish mysqli support PAM authentication. I'm wish to use pam_krb.so

Description:
------------
PHP fails to authenticate against MariaDB using PAM authentication. 

You can find all details in https://bugs.php.net/bug.php?id=68281, which has
been reported against mysql extension and closed only because that extension has been deprecated
meanwhile, however exactly same problem exists in MySQLi as well.

I've checked current git and the dialog plugin is still not there, so this applies to all PHP
versions so far.
