PAM enables a system to use a standard interface to access various kinds of authentication methods, such as Unix passwords or an LDAP directory.
Cleartext Client-Side Authentication Plugin
client-side plugin can be used to send the password to the server in clear text. There is no corresponding server-side plugin.
I have read documentation but could not get enough help, PAM authentication is supported only in MySQL Enterprise edition but cleartext authentication is applicable to all MySQL servers as it's a client who invokes this kind of authentication mechanism.
Has anybody practically tried using PAM authentication or Cleartext authentication plugin?
If so please explain how to configure and setup with an example?
