Appion

h1. Deciding on Enforcing User Authentication

Purpose of optional user authentication system in combination of Project Management in the Leginon/Appion Database Tools on the webserver is to provide different levels of user privileges at institution where the webserver is available to all.  In addition, by assigning project owners, users in the lower privileged group will not see projects from others.  It makes finding an experiment session easier once data are accumulated.  Enabling of the system is not required, but is recommended if the web server can be accessed freely outside the intended group.  Once enabled, all myamiweb pages cannot be accessed without login.

Four levels of group privileges are included with the installation, and four user groups are created by default to reflect them, respectively

|All at administration level|administrators|

|View all but administrate owned|power users|

|Administrate/view only  owned projects and view shared experiments|users|

|View owned projects and shared experiments|guests|
