Creating, Deleting, Inactivating User Accounts

Creating, Deleting, Inactivating User Accounts

A user account includes a unique identifier, password, and one or more permissions. The Administrator account is created during the initial login to a new DAC installation.
After a user account is created, the Administrator must distribute the DAC repository authentication file to users in order for the users to be able to log into the DAC Client (and access the DAC repository) using their own user name and password.
