User names must come from a common source. You must define the source before you can add users to Serena Dashboard. Users can come from any of the following:
Serena Single Sign-on: use Serena SSO if you have installed and configured SSO as part of your SBM implementation.
LDAP Server: if your organization uses LDAP to centrally manage all users, you can connect to the LDAP server and then choose which users from the LDAP server to add to Dashboard.
Dashboard user database: You can optionally choose to store all users locally in the Dashboard database.
You can choose the login source and define settings for each from the Administration view in Serena Dashboard.
