• Key Concepts: 
  The Login Module Stack is a component of the BC-SEC Security module in SAP. It is a set of authentication modules that are used to authenticate users when they log into the system. The Login Module Stack is composed of several different authentication modules, such as the User ID and Password module, the X.509 Certificate module, and the Kerberos module. Each authentication module has its own set of rules and requirements for authentication. 
  
  How to use it: 
  The Login Module Stack is used to authenticate users when they log into the system. When a user attempts to log in, the Login Module Stack will check each authentication module in order until it finds one that can successfully authenticate the user. Once authenticated, the user will be granted access to the system. 
  
  Tips & Tricks: 
  When configuring the Login Module Stack, it is important to ensure that all authentication modules are configured correctly and that they are in the correct order. This will ensure that users are authenticated correctly and securely. Additionally, it is important to keep the Login Module Stack up-to-date with any security patches or updates that may be released by SAP.
