When connecting to the PresSTORE user interface, a login is required. The validation of username and password, (the authentication) is not done by PresSTORE itself but passed on to the operating system. This implies that usernames and passwords are accepted in the same way as they are accepted by the operating system.
On Mac and Linux, PresSTORE supports the so called PAM (Pluggable authentication module) interface. This means that the authentication scheme used by PresSTORE can be customized by adapting a simple configuration file to fit your needs.
The PresSTORE PAM configuration is stored in the file /etc/pam.d/nsd. Please note that the default configurations installed on Mac and Linux are different.
Please understand that we cannot offer further support in how to modify the PAM configuration, the file however is very simple and there is lot of information on the Internet about PAM and the according configuration file, e.g. on the following links:
