# 17.8. User Identification

When a user logs into a system, they are assigned a user name and a corresponding UserID. This user name is used by the LPRng software when transferring jobs to identify the user.

When we look into the problem of authentication, we will possibly have a more global user identification to deal with, the authentication identifier (AuthID). One way to deal with this problem is to give LPRng intimate knowledge of the UserID and AuthID relationship. While this is possible it is difficult to deal with in a simple and extensible manner. An alternate solution is to provide a mapping service, where the authentication procedure provides a map between the UserID and AuthID.
